Characteristics and behavior of newly listed firms: Evidence from the Asia-Pacific region

We examine the size, profitability and delisting experience during 1980–1999 of new lists in the Pacific Basin countries. We also examine the impact of the legal environment on post-listing behavior. We find that new lists are more numerous in common law countries. They are smaller than seasoned firms, regardless of legal regime. New lists are more profitable in civil law countries, but this is due to the high profitability of Japanese new lists. Asian new lists have lower rates of delisting compared to U.S. firms. The delisting frequency of seasoned firms exceeds that of new lists for our sample countries.     

Discrete-time bond and option pricing for jump-diffusion processes

This paper provides a methodology for numerically pricing generalized interest rate contingent claims for jump-diffusion processes. The method enhances the standard finite-differencing approach to deal with partial differential-difference equations derived in a jump-diffusion setting. Numerical illustrations compare jump-diffusion and pure-diffusion models.I am especially grateful to Darrell Duffie, who provided me immensely valuable input on the paper. I would also like to thank Dilip Madan and Rangarajan Sundaram for alleviating my confusion with helpful comments.     

Specification tests based on the heterogeneous generalized gamma model of duration: With an application to Kennan's strike data

In this paper, tests for neglected heterogeneity and functional form misspecification of some commonly used parametric distributions are derived within a heterogeneous generalized gamma model. It is argued that the conventional test of heterogeneity may not be valid when the underlying hazard function is misspecified. Hence, if the estimated hazard function is deemed restrictive, tests for functional form misspecification should accompany any test of heterogeneity. An empirical illustration based on Kennan's (1985) model of strikes is used to show that incorrect inferences may be drawn, as in a number of previous analyses, if the relevant restrictions are not tested jointly.     

Did CDS trading improve the market for corporate bonds?

Financial innovation through the creation of new markets and securities impacts related markets as well, changing their efficiency, quality (pricing error), and liquidity. The credit default swap (CDS) market was undoubtedly one of the salient new markets of the past decade. In this paper we examine whether the advent of CDS trading was beneficial to the underlying secondary market for corporate bonds. We employ econometric specifications that account for information across CDS, bond, equity, and volatility markets. We also develop a novel methodology to utilize all observations in our data set even when continuous daily trading is not evidenced, because bonds trade much less frequently than equities. Using an extensive sample of CDS and bond trades over 2002–2008, we find that the advent of CDS was largely detrimental. Bond markets became less efficient, evidenced no reduction in pricing errors, and experienced no improvement in liquidity. These findings are robust to various slices of the data set and specifications of our tests.     

Fee Speech: Signaling, Risk-Sharing, and the Impact of Fee Structures on Investor Welfare

The fee structure used to compensate investment advisers iscentral to the study of fund design, and affects investor welfarein at least three ways: (i) by influencing the portfolio-selectionincentives of the adviser, (ii) by affecting risk-sharing betweenadviser and investor, and (iii) through its use as a signalof quality by superior investment advisers. In this paper, wedescribe a model in which all of these features are present,and use it to compare two popular and contrasting forms of feecontracts, the "fulcrum " and the "incentive " types, from thestandpoint of investor welfare. While the former has some undeniablyattractive features (that have, in particular, been used byregulators to justify its mandatory use in a mutual fund context),we find surprisingly that it is the latter that is often moreattractive from the standpoint of investor welfare. Our modelis a flexible one; our conclusions are shown to be robust tomany extensions of interest. The results are also extended toconsider unrestricted fee structures and competitive marketsfor fund managers.     

An approximation algorithm for optimal consumption/investment problems

This article develops a simple approach to solving continuous-time portfolio choice problems. Portfolio problems for which no closed-form solutions are available may be handled by this technique, which substitutes the numerical solution of partial differential equations with a non-linear numerical algorithm approximating the solution. This paper complements the wide literature in economics on the solution of dynamic problems in discrete time using projection methods. Our approach extends the approximation function to power forms, which are shown to fit finance type problems well. The algorithm is parsimonious, and is first illustrated by solving two basic examples, first, the standard Merton problem, and second, a jump-diffusion problem. Then, we demonstrate that the model is easy to implement on a larger scale, by optimizing a portfolio of six stock indexes, and stochastic volatility driven by two correlated state variables.

Incentives for creativity

We investigate whether piece-rate and competitive incentives affect creativity, and if so, how the incentive effect depends on the form of the incentives. We find that while both piece-rate and competitive incentives lead to greater effort relative to a base-line with no incentives, neither type of incentives improve creativity relative to the base-line. More interestingly, we find that competitive incentives are in fact counter-productive in that they reduce creativity relative to base-line condition. In line with previous literature, we find that competitive conditions affect men and women differently: whereas women perform worse under competition than the base-line condition, men do not.     

Political Party Affiliation of the President,Majority in Congress,and Sin Stock Returns

We find that in contrast to the stock market, which performs better during Democratic presidencies, “sin” stocks—publicly traded producers of tobacco, alcohol, and gaming—perform better during Republican presidencies and even more so when the Republican presidency is accompanied by a Republican majority in at least one chamber of Congress. We examine whether sin firms use contributions to establish connections with politicians and find that sin firms contribute more to Republican candidates and that these contributions are greater when Republicans are in power. We also find a positive relation between political contributions and future returns. The relation is stronger for contributions to Republicans.
