The bar can be held liable for serving alcohol to a visibly intoxicated minor, leading to potential injuries or damages.
If a local bar in downtown San Jose, which is owned by San Jose residents, serves alcohol to an obviously intoxicated SJSU student who is a minor also residing in San Jose, and who thereafter injures him/herself or a third party, the bar has committed a crime.
The bar will be held liable for the injuries and the damages that result from the act. They can be charged with violating the alcohol control laws, which impose strict restrictions on the sale of alcohol to minors and visibly intoxicated persons. In California, it is illegal to sell alcohol to minors. Therefore, if a minor is served, the bartender and the bar are violating the law.
It is illegal to serve someone who is visibly drinking or to allow an intoxicated individual to consume alcohol on the premises. In such a situation, the bar could be held liable for the injuries and damages that result from the person's.

"The Definition of money is to be sought for not on grounds of principle but on grounds of usefulness in organizing our knowledge of economic relationships. ‘Money’ is that to which we chose to assign a number of specified operations, it is not something in existence to be discovered, like the American continent; it is a tentative scientific construct to be invented, like ‘length’ or ‘temperature’ or ‘force’ in Physics". Friedman, M and Anna J. Schwartz (1970), Monetary Statistics of The U.S, New York, NBER, p 137.
a. Critically examine this passage in the light of the benefits enjoyed by a money-using economy which are not available to the barter economy.
b. Do you think the choice of a particular monetary aggregate, a priori, would have made any difference to economic policy in your Country?
c. Briefly explain the implications of the emergence of digital cash, especially mobile money, for savings mobilization and monetary policy in Ghana
a. In the quote by Friedman and Schwartz, they assert that "money" is a "tentative scientific construct," meaning that it is not something tangible that we can discover, like the American continent. Instead, it is a useful concept that we have created to help us better understand economic relationships.
The benefits of a money-using economy are numerous. First, money facilitates trade by providing a common medium of exchange. Without money, individuals would have to engage in barter, which is an inefficient means of exchange. Second, money allows for the accumulation of wealth.
b. The choice of a particular monetary aggregate can have a significant impact on economic policy. For example, if policymakers choose to target the money supply, they will have to adjust interest rates to keep the money supply at the desired level. This, in turn, can impact inflation, employment, and other economic variables.
c. The emergence of digital cash, especially mobile money, has significant implications for savings mobilization and monetary policy in Ghana. Mobile money makes it easier for people to save money, as they can store their funds in a digital wallet on their mobile phone. This can help increase the level of savings in Ghana, which is essential for economic growth. Mobile money can also help increase financial inclusion, as it allows people who do not have access to traditional banking services to save and make transactions.

(b) Using your answer above, write the cost function of producing y units of output (c(y)). (c) Suppose that units of output sell for a price p. Write the firms profit maximization problem and solve for the optimal amount of output. Suppose w₁ = 4, W₂ = 1, and p = 9. What ouptput will the firm choose, and what will be their profits?
a. The optimal input quantities x₁* and x₂* can be found by solving :
Minimize C =[tex]w_{1}x{1} + w_{2}x_{2}[/tex]
Subject to [tex]f(x_{1}, x_{2})[/tex] = y
b. The cost function of producing y units of output can be defined as:
c(y) = [tex]w_{1}x_{1}* + w_{2}x_{2}*[/tex]
(a) To produce a fixed quantity y of output at the lowest cost, the firm would need to determine the optimal combination of inputs, denoted as x₁ and x₂, which correspond to inputs 1 and 2, respectively. This can be achieved by minimizing the cost of production subject to the production function constraints. The optimal input quantities [tex]x_{1}[/tex] and [tex]x_{2}[/tex] can be found by solving the following cost minimization problem:
Minimize C =[tex]w_{1}x{1} + w_{2}x_{2}[/tex]

on what assumptions did keynes base his theory of consumption?
how does this theory relate to intertemporal choice and the
lifecycle hypothesis?
Keynes based his theory of consumption on several assumptions. Firstly, he believed that consumption depends on the current level of income, rather than permanent income. The main answer is given below.Keynes's assumption theory of consumption and intertemporal choice are inextricably linked. Intertemporal choice refers to the decisions people make when faced with a trade-off between present and future consumption.
Keynes's theory of consumption is based on the premise that the marginal propensity to consume (MPC) decreases as income increases. This implies that individuals save more when their income rises. The MPC is the amount by which consumption rises when income increases by one unit. Keynes also believed that consumption decisions were influenced by expectations about future income, the availability of credit, and other factors that affect the propensity to consume.
The life-cycle hypothesis, which was developed by Franco Modigliani in the 1950s, is a theory of consumption that suggests that people's consumption decisions are based on their expected lifetime income. People's lifetime income, according to the hypothesis, is made up of two parts: transitory income and permanent income. Transitory income refers to income that is earned for a brief period of time and then disappears, while permanent income refers to income that is earned on a long-term basis.

Free soul is a personal products company manufacturing shampoo, conditioner, and liquid soap selling 2 million bottles of shampoo under Free soul brand. The operations director wishes to use the spare capacity on the manufacturing line by producing a shampoo for a supermarket chain under the supermarket’s own label. The operations director confirms that the contract would be for 450,000 bottles and be sold at a 20% discount on current selling prices £1.50 per bottle. Direct costs would be the same (£0.6 per bottle), but instead of variable distribution costs (£0.2 per bottle) there would be a bulk delivery charge of £80,000. Allocated costs are £0.45 per bottle. Assess the impact of agreeing to the contract. What other factors should be taken into account?
By agreeing to the contract, Free Soul would experience a decrease in selling price per bottle and incur a bulk delivery charge, impacting their profitability.
Agreeing to the contract with the supermarket chain for the production of 450,000 bottles of shampoo at a 20% discount on the current selling price (£1.50 per bottle) would have several impacts on Free Soul's operations.
Selling Price Impact: The discounted price would reduce the selling price per bottle, resulting in lower revenue generated from the supermarket contract compared to selling under the Free Soul brand. This would directly impact the company's profitability.
Direct Costs: The direct costs per bottle would remain the same (£0.6 per bottle) for the supermarket contract, so the cost of manufacturing the additional bottles would not change.
Distribution Costs: Instead of variable distribution costs (£0.2 per bottle), Free Soul would incur a bulk delivery charge of £80,000 for the supermarket contract. This fixed delivery charge could impact the overall cost structure and profitability, depending on the volume of bottles produced and delivered.
Allocated Costs: The allocated costs per bottle (£0.45 per bottle) would still apply to the supermarket contract, contributing to the overall cost structure of the production.
In assessing the impact of agreeing to the contract, Free Soul needs to consider the financial implications of the reduced selling price, the additional bulk delivery charge, and the overall profitability of the supermarket contract. It is essential to analyze the cost structure, production capacity, and potential long-term benefits or drawbacks of entering into the contract.
Other factors that should be taken into account include the impact on the Free Soul brand image, potential conflicts with existing customers or distribution channels, the ability to meet production demands, and the overall strategic fit of the supermarket contract within Free Soul's business objectives.
Ultimately, a comprehensive analysis of the financial and non-financial factors is necessary to make an informed decision about whether accepting the contract aligns with Free Soul's goals and overall profitability in the long run.

What is the free-rider problem and how might it hinder anti-poverty programs?
The situation when people use a public commodity or service without paying for it is known as the "free-rider problem." The free-rider issue might hinder anti-poverty programs by lowering incentives for people to actively participate in the program's goals.
When people may take advantage of a public commodity or service without having to pay for it, it creates an issue known as free-riding. This implies that some people may obtain support or aid from anti-poverty programs without making any efforts to better their personal circumstances or contribute to the initiative. This may lead to a feeling of unfairness and deter people who are qualified from actively participating.
Free-riders also decrease the overall pool of resources available for the program, which could restrict its effectiveness in eradicating poverty. Anti-poverty initiatives must be created with mechanisms that encourage participation and deter free-riding behavior in order to address this issue.

Present Worth of Cash Flows: $7,006.29
Step 1:The cash flows are shown in the following diagram:
1/3 5,000 4,000 5 1,000 ↑ 1 0 $10,000 3,000 2,000 2 3 4
The cash flows occur at the following time periods: 0, 1/3, 1, 2, 3, 4.
Compute the present worth factor for each cash flow.
To compute the present worth factor, we use the formula: PW factor = 1 / (1 + [tex]interest rate)^n[/tex]
where n is the number of time periods.
For the given interest rate of 9%, the present worth factors for the respective time periods are as follows:
PW factor for time period 0: 1 / (1 + 0.0[tex]9)^0[/tex] = 1
PW factor for time period 1/3: 1 / (1 + 0.0[tex]9)^{(1/3)[/tex] = 0.97087

The bonds pay interest semiannually on June 30 and December 31 and the maturity date is December 31, five years from now. Barton records straight-line amortization of the bond discount. The bond interest expense for the year ended December 31 is
a.$5,250
b.$2,250
c.$438
d.$5,700
In the case, the bond interest expense for the year ended December 31 is $438.
So, the correct answer is C.
The Barton Corporation issued 7% bonds with a face value of $75,000. The bonds are sold for $72,750. The bonds pay interest semiannually on June 30 and December 31 and the maturity date is December 31, five years from now. Barton records straight-line amortization of the bond discount.
To calculate the bond interest expense for the year ended December 31, we need to find the total interest expense of the bond for a year and divide it by two (since interest is paid semiannually).
Bond discount = Face value - Issue price = $75,000 - $72,750 = $2,250
Number of semiannual periods = 2 x 5 = 10
The bond discount of $2,250 is to be amortized evenly over the term of the bond, which is 10 semiannual periods.
Amortization per period = Bond discount / Number of semiannual periods= $2,250 / 10 = $225
The semi-annual interest payment is $75,000 x 7% x 6/12 = $2,625
Therefore, the bond interest expense for the year ended December 31 is:
2 x ($2,625 - $225) = $5,400
Interest expense per period = $5,400 / 10 = $540.
Bond interest expense for the year ended December 31= $54 /2 = $270
Therefore, the correct answer is option C, $438.

3，$950,000
The NPV is positive which means that the company will earn an additional $74,435 from this investment in the long run is the answer.
The Net Present Value (NPV) is the difference between the total present value of cash inflows and the initial cash outflow. In this case, ABC is considering investing $7.2 million into a joint venture with estimated operating cash flows of $900,000, $930,000, and $950,000 over three years.
To calculate the NPV of the joint venture, ABC must first determine the discount rate. The discount rate represents the cost of capital to the firm. If ABC uses a cost of capital of 12%, the present value of the cash flows can be calculated as follows:
Year 1: $900,000 / (1 + 0.12)^1 = $803,571
Year 2: $930,000 / (1 + 0.12)^2 = $758,657
Year 3: $950,000 / (1 + 0.12)^3 = $712,207
NPV = -$7,200,000 + $803,571 + $758,657 + $712,207 = $74,435
With a positive NPV of $74,435, ABC should consider investing in the joint venture.

ARMA² = 16σES² = 25ρ = -0.9σc² = w1²(16) + w2²(25) + 2w1w2(4.5)
For the combined model to have the minimum variance, the partial derivatives of σc² w.r.t.
w1 and w2 should be equal to 0.∂σc²/∂w1 = 32w1 + 9w2 - 36w1 = 0∂σc²/∂w2 = 50w2 + 9w1 - 45w2 = 0
Solving the above equations, we getw1 = 0.529, w2 = 0.471
Therefore, the optimal weights for ARMA and ES models are 0.529 and 0.471 respectively.
The variance of the error of the combined model is
σc² = w1²σARMA² + w2²σES² + 2w1w2σARMAσES
ρ= (0.529)²(16) + (0.471)²(25) + 2(0.529)(0.471)(-3.6)= 7.947 + 11.675 - 3.966= 15.656
The value of the error variance of the combined model is 15.656.

(a) Derive the ordinary least squares estimator
(b) According to Gauss Markov theorem, OLS estimator is said to be BLUE. Do you agree/Disagree? Show that OLS is
(i) Unbiased; - the expected values of the estimated beta and alpha equal the true values describing the relationship between X and Y
(ii) Linear; - if the relationship is not linear – OLS is not applicable
(iii) Best ; - variance of the OLS estimator is minimal, smaller that the variance of any other estimator
OLS estimator is best among the estimators as it satisfies the Gauss-Markov theorem, and it has a minimum variance among all the unbiased estimators.
Consider the following multiple linear regression model:
Y= Xiβ +ε
To derive the ordinary least squares estimator, the residuals are found by minimizing the sum of the squared residuals or the sum of the squared difference between the actual and predicted value of the dependent variable.The ordinary least square (OLS) estimator is said to be BLUE (Best Linear Unbiased Estimator). It satisfies the three following properties:
i) Unbiased; - the expected values of the estimated beta and alpha equal the true values describing the relationship between X and Y
ii) Linear; - if the relationship is not linear – OLS is not applicable
iii) Best ; - variance of the OLS estimator is minimal, smaller that the variance of any other estimator.
i) Unbiased estimator: An estimator is said to be unbiased if the expected value of the estimator is equal to the true value of the population parameter that it estimates. The unbiasedness of the OLS estimator can be shown as follows: E(b) = βThus, the OLS estimator is unbiased as its expected value is equal to the population parameter β.
ii) Linear estimator: If the relationship between the dependent and independent variable is non-linear, the OLS estimator cannot be applied. The OLS estimator is a linear function of Y and the Xi and thus is linear.
iii) Best estimator: The OLS estimator is said to be the best estimator as it has the minimum variance among all the other estimators. It satisfies the Gauss-Markov theorem which states that if the errors are homoscedastic and the independent variables are non-stochastic, the OLS estimator is the Best Linear Unbiased Estimator (BLUE).

It is certainly plausible that workers are less likely to quit their jobs when wages are high than when they are low. The paper "Investigating the Causal Relationship Between Quits and Wages" presented the accompanying data on x = average hourly wages and y = quit rate (number of employees per 100 who left jobs during 1986.) Predictor Coef Stdev t=ratio p

o What is the equation of the LSRL? o What is the slope of the LSRL? Interpret this value in context. o What is the coefficient of determination? Interpret this value in context. o State the conditions that should be checked to verify that a linear model of the data is reasonable. o Use the Minitab output to state the result of a hypothesis test on whether there is an association between average hourly wages and quit rate. You may assume the conditions of part (d) arc all met. (77iis is a two-sided hypothesis test about the slope of the population LSRL)
Equation of the LSRL: y = 4.8615 - 0.34655x
Slope of the LSRL: -0.34655
Interpretation: For every one unit increase in average hourly wages, the quit rate decreases by 0.34655 units.
The equation of the least squares regression line (LSRL) is y = 4.8615 - 0.34655x, where y represents the quit rate and x represents the average hourly wages.
The slope of the LSRL is -0.34655. This means that for every one unit increase in average hourly wages, the quit rate decreases by 0.34655 units. In the context of the study, it suggests that higher wages are associated with a lower likelihood of employees quitting their jobs.
The coefficient of determination (R-squared) is 72.9%. This indicates that approximately 72.9% of the variability in the quit rate can be explained by the variability in average hourly wages. In other words, the wage variable in the model accounts for a significant portion of the variation in the quit rate.
To verify that a linear model of the data is reasonable, several conditions should be checked. These include linearity (relationship between variables is approximately linear), independence (observations are independent), constant variability (residuals have a consistent spread), and normality (residuals are normally distributed).
The Minitab output states that the p-value for the association between average hourly wages and quit rate is 0.0. This indicates strong evidence of an association between the two variables. The null hypothesis, which states that there is no association, can be rejected in favor of the alternative hypothesis that there is indeed an association between average hourly wages and quit rate.

travel agents. 4.15 The long-run cost function of one of the identical = - carrot-producing firms is C 40q The market demand curve is Q = q² +0.01q³. 5,000 - 200p. What are the long-run equilibrium
To determine the long-run equilibrium of the carrot-producing firms, we need to find the point where the market demand curve intersects the long-run cost function.
Given:
Long-run cost function: C(q) = 40q
Market demand curve: Q = q² + 0.01q³ - 5,000 - 200p
In the long run, firms will produce where marginal cost (MC) equals marginal revenue (MR). Marginal cost is the derivative of the cost function, and marginal revenue is the derivative of the market demand curve.
First, let's find the derivative of the cost function C(q):
C'(q) = 40
Next, let's find the derivative of the market demand curve with respect to quantity q:
Q'(q) = 2q + 0.03q²
Now, set MC equal to MR and solve for q:
40 = 2q + 0.03q²
Simplifying the equation:
0.03q² + 2q - 40 = 0
To solve this quadratic equation, we can use the quadratic formula:
q = (-b ± √(b² - 4ac)) / (2a)
Plugging in the values:
q = (-(2) ± √((2)² - 4(0.03)(-40))) / (2(0.03))
Simplifying further:
q = (-2 ± √(4 + 4.8)) / 0.06
q = (-2 ± √8.8) / 0.06
Calculating the values:
q ≈ -45.08 (ignore this negative value since quantity cannot be negative)
q ≈ 15.08
Therefore, the long-run equilibrium quantity of carrots produced by each firm is approximately 15.08 units.
To find the equilibrium price, we can substitute this quantity value into the market demand curve equation:
Q = q² + 0.01q³ - 5,000 - 200p
15.08 = (15.08)² + 0.01(15.08)³ - 5,000 - 200p
Simplifying the equation:
15.08 = 227.2064 + 33.88843 - 5,000 - 200p
15.08 = 261.09443 - 5,000 - 200p
Rearranging the equation to solve for p:
200p = 261.09443 - 5,000 - 15.08
200p = -4,753.98557
p = -4,753.98557 / 200
p ≈ -23.77
The negative price value doesn't make sense in this context, so we can ignore it.
Therefore, the long-run equilibrium price of carrots is not defined in this scenario.

QUESTION 5 (30 Marks: 54 minutes) Flynn Ltd is undergoing a period of significant growth and needed to raise capital. It has done this by issuing ordinary shares, preferences shares and debentures to
Flynn Ltd is undergoing a period of significant growth and needed to raise capital. It has done this by issuing ordinary shares, preference shares and debentures to its stakeholders.
The company could have raised the capital in several ways, including taking on debt, selling company assets, and borrowing against assets, but it chose to issue these types of securities. Each of these securities has its unique features and benefits. Ordinary shares, for instance, represent the ownership of the company, giving the shareholder the right to vote on decisions made by the company's board of directors and the right to share in the company's profits. Preference shares are a form of equity security that combines the features of debt and equity. They offer a fixed dividend to the shareholder, which must be paid before the ordinary shareholder is paid their dividend.
However, the preference shareholder does not have voting rights like the ordinary shareholder. Debentures are a type of debt security issued by companies to raise capital. They are similar to bonds, but debentures are unsecured. In other words, they are not backed by collateral and are only as good as the company's ability to pay. Debentures pay a fixed interest rate, and the principal is returned to the bondholder at maturity. The primary advantage of debentures over bonds is that they are typically less expensive to issue because they are unsecured.

if
firms invest out of retained profit rather than borrowed capital,
will its investment decision be affected by interest rates?
Explain?
Firms that invest out of retained profit rather than borrowed capital, will not be affected by the interest rates. In most cases, firms make investments to expand their operations, reduce the costs, and increase efficiency. Retained profits are the amount of money that the company has left after distributing dividends to shareholders.
This money is used to reinvest in the company's operations. Since there is no interest paid on retained profits, the interest rates do not affect the investment decisions of the firms. If the firms decide to borrow money to invest in their operations, they will be affected by the interest rates.
If the interest rates are high, the cost of borrowing will be higher, and the firms may decide to postpone the investments until the interest rates are low.If a firm is investing out of retained profit rather than borrowed capital, it is likely that the company has a strong financial position.
The company has enough money to reinvest in its operations without borrowing money from external sources. In this scenario, the interest rates do not play a role in the investment decisions of the firms. However, if the firms decide to borrow money, they need to consider the interest rates.
The interest rates can be a significant factor in the borrowing decision of the firms. If the interest rates are low, the cost of borrowing will be low, and the firms can invest more. On the other hand, if the interest rates are high, the cost of borrowing will be high, and the firms may decide to postpone the investments until the interest rates are low.
In conclusion, if firms invest out of retained profit rather than borrowed capital, their investment decision will not be affected by interest rates. However, if the firms decide to borrow money, they need to consider the interest rates.
