Codes :
This question requires matching economic concepts from List I with the economists or related works/concepts from List II.
Key Economic Concepts and Matches
We need to match the following:
- a. The Screening Hypothesis
- b. Job Market Signalling
- c. The problem of moral hazard in the case of medical insurance
- d. The market for lemons
With the corresponding items from List II:
- 1. George A. Akerlof
- 2. K.J. Arrow
- 3. M. Spence
- 4. Paul W. Miller and Paul A. Volcker
Matching Process
Let's identify the established pairings based on economic literature:
- The market for lemons (d) is a seminal concept introduced by George A. Akerlof. Thus, (d) matches with (1).
- Job Market Signalling (b) is primarily associated with the work of M. Spence. Thus, (b) matches with (3).
- The problem of moral hazard in the case of medical insurance (c) is a key topic in health economics, extensively analyzed by K.J. Arrow. Thus, (c) matches with (2).
- The Screening Hypothesis (a), in the context of the provided options, is matched with Paul W. Miller and Paul A. Volcker (4). This pairing aligns with the provided correct answer.
Final Matching Table
| List I Item | List II Item | Reason |
|---|---|---|
| a. The Screening Hypothesis | 4. Paul W. Miller and Paul A. Volcker | As per the provided correct option. |
| b. Job Market Signalling | 3. M. Spence | Developed by Michael Spence. |
| c. The problem of moral hazard in the case of medical insurance | 2. K.J. Arrow | Analyzed by Kenneth Arrow in health economics. |
| d. The market for lemons | 1. George A. Akerlof | Introduced by George A. Akerlof. |
Conclusion
Based on the matches derived, the correct combination is (a)-(4), (b)-(3), (c)-(2), (d)-(1).
This corresponds to Option 3.
Important Questions from Information Theory
A source transmits symbols from an alphabet of size 16. The value of maximum achievable entropy (in bits) is _______
An analog baseband signal, bandlimited to 100 Hz, is sampled at the Nyquist rate. The samples are quantized into four message symbols that occur independently with probabilities $p_1 = p_4 = 0.125$ and $p_2 = p_3$. The information rate (bits/sec) of the message source is ____________
The random variable $X$ takes values in $\{-1, 0, 1\}$ with probabilities $P(X = -1) = P(X = 1)$ and $\alpha$ and $P(X = 0) = 1 - 2\alpha$, where $0 < \alpha < \frac{1}{2}$. Let $g(\alpha)$ denote the entropy of $X$ (in bits), parameterized by $\alpha$. Which of the following statements is/are TRUE?
- Consider a discrete memoryless source with an alphabet of four source symbols.
$s(t)$ is a multi-level (-1, 0, +1, +2) signal representing a long sequence of random symbols from the above source which is generating $10^4$ symbols per second.
Which of the following options is the correct value of equivalent Nyquist bandwidth of $s(t)$? An information system uses the following daily workflow. Each function can start only after the input it explicitly requires has been produced. Arrange the functions in execution order.
(A) Process and validate the day’s sales transactions.
(B) Update the inventory master file using the validated transactions.
(C) Process managers’ enquiries using the figures in the completed daily report.
(D) Generate the daily report from the updated inventory master file.
(E) Run interactive decision-support scenarios using the results returned by those enquiries.
