I show that the seller can verify her precision by employing a non-linear contract. I derive the equilibrium fee for information as a function of the seller's incentives, the sales volume, and buyers' trading intensity. I also analyse the implications of allowing the seller to trade on her own account for truthfulness and precision choice.

I show that the incumbent's optimal access strategy balances her demand for positive coverage with the public's demand for credible coverage. The media's access increases with the competence of politicians over issues under public focus. Controlling media's access can be instrumental in influencing public opinion, especially in the hands of popular incumbents. Persistence of key election issues, however, decreases the effectiveness of media access control by incumbents.

We show that the board’s monitoring intensity and the equilibrium pay-performance sensitivity of CEO’s pay are increasing in the board’s independence from the CEO. JEL Classification: G30, G32

The analysis shows that, as well mitigating a moral hazard problem on the issuer's side, skin in the game requirements can also improve the rating accuracy of a CRA involved in the sale. The results also link the accuracy of the CRA's ratings to the severity of the issuer's moral hazard problem. A more nuanced skin in the game rule that accounts for the specifics of the underlying security class can be more desirable rather than the proposed "one size fits all" rule.

The collaborative behavior varies starkly depending on the shape of marginal effort cost, or project's "difficulty." In the unique (interior) equilibrium, higher ability collaborators work less and thus receive lower credit and payoff for "easy" projects, while the reverse holds for "difficult" projects. Despite free-riding, the team equilibrium may involve over-investment. Social efficiency requires over-rewarding collaborative work and under-rewarding solo work. The incentives to team up and the impact of effort monitoring on credit attribution are also investigated.

While an incumbent prefers positive bias, granting access improves her re-election probability only if coverage is sufficiently credible in the eyes of the public. Information gatekeeping can induce a quid pro quo relationship: media provides coverage with positive bias in exchange of future access, thereby affecting electoral outcomes in favor of incompetent incumbents. The degree of access media enjoy increases with competence of incumbents over those issues under public focus.

The available media outlets differ in their ''toughness'' towards the politician. An interview with a tougher media outlet is more informative, but is also more likely to yield a negative outcome. The choice of the media outlet determines the accuracy of the information that flows to the public and the volume of citizens who consume that information. The analysis shows that (1) politicians who enjoy sufficient popularity are likely to avoid tough media outlets, (2) when seeking approval for controversial agendas, politicians are more likely to appear in tougher outlets.

In a setting where a public disclo-sure of the central bank's target is not desirable for effective interven-tion, we show that selectively disclosing the target to another informed market participant, such as another central bank or a large currency trader, may result in better targeting relative to a regime of complete secrecy. In particular, if the market's uncertainty over the bank's tar-get is sufficiently high and if the central bank is leaning against the wind -attempting to move the exchange rate in the opposite direction of where the fundamental based trade takes it -selective disclosure is the preferred intervention regime.

An issuer solicits a rating from a CRA to sell a loan portfolio. The sale is subject to a retention requirement to mitigate a moral hazard problem. The CRA's optimal rating accuracy is shown to be increasing in the issuer's skin. The analysis relates the optimal retention rule to the CRA's information acquisition problem. The issuer's skin in the game and the CRA's rating accuracy are shown to be substitute mechanisms for eliciting effort from the issuer.

This paper analyzes the implications of the manager's hedging ability on her optimal compensation scheme, incentives and firm value. We allow the manager to adjust her systematic risk exposure by trading the market portfolio. We find that (i) the manager's optimal hedge depends on the liquidity of the market. With imperfect liquidity, the manager's optimal hedge is not complete and she bears some systematic risk. (ii) The equilibrium pay-performance sensitivity is decreasing in the company's beta and increasing in the market liquidity. (iii) Since better hedging ability increases the manager's equilibrium incentives, the firm value increases in the liquidity of the market where systematic risk is traded. This last result contrasts with previous studies that suggest a negative relationship between stock market liquidity and production efficiency.

The main results are as follows: Without any hedging ability, the manager underinvests in risk at the firm level to diversify his own compensation risk. If the manager can trade a security correlated with firm specific risk, the underinvestment in risk is reduced, optimal managerial share ownership and equilibrium effort increase. If the manager can hedge by simulating the sale of his shares, however, he can completely undo any incentive scheme. The model predicts that a higher degree of financial market development implies higher managerial share ownership and more efficient risk taking at the firm level.

If so, how? From a global perspective, does the presence of incomplete information weaken or strengthen the case for MFN? We examine these questions in a model of imperfect competition with two asymmetric exporters and a single importing country who is imperfectly informed about exporters' costs. Despite the lack of complete information, the importing country prefers discrimination to MFN. However, equilibrium tariff dispersion is lower under incomplete information. As a result, the global welfare gain from MFN, while still positive, is smaller under incomplete information relative to the case of complete information.

We show that an exclusive financing relationship arises endogenously in equilibrium due to initial lender's superior information on the project's progress. The analysis also identifies a novel distortionary effect of exclusivity and the consequent loss of future rents on the ex-ante choices of the borrower. When she chooses the amount of funds to be initially invested in the project, the borrower chooses to overinvest making the future rent extraction by the initial lender as costly as possible.

In a binary message and state space, I show that the analyst's reward scheme essentially provides him with a portfolio endowment traded in the market. Regardless of the true signal, the analyst issues the report that corresponds to the portfolio endowment with maximum market value, given security prices. The analyst's information acquisition incentive is driven only by private portfolio considerations: he acquires information only if he will be holding a large enough position in the stock he covers.

Once the venture is started, the entrepreneur chooses an action that determines the riskiness of the venture's payoff. When action choice is contractible, the optimal risk sharing consideration under limited liability calls for a pure debt contract and the low risk action is adopted. When the action choice is not contractible, due to the risk shifting problem implementing the low risk action requires a deviation from the optimal risk sharing. I focus on situations where despite this deviation, the risk averse investor prefers to implement the low risk action and show that a convertible debt contract is superior to pure debt, pure equity and any mixture of debt and equity.

I show that increasing the manager's portfolio share increases her demand for precise information. This result contrasts with the existing irrelevance results where the manager's portfolio share does not affect her precision choice. The irrelevance result relies on the manager facing a constant asset price, regardless of her demand. In a noisy rational expectations framework, increasing the manager's share decreases her demand and results in a less informative asset price. Thus, the manager gathers more precise information when offered a larger fraction of portfolio returns.
