This paper develops and implements a semiparametric estimator for investigating, with panel data, the importance of human capital and time nonseparable preferences to females when aggregate shocks are present. It provides a set of conditions for making statistical inferences about agents' expectations of their correlated future choices, from a short panel. Under the assumption that observed allocations are Pareto optimal, a dynamic model of female labour supply and participation is estimated, in which experience on the job raises future wages, and time spent off the job in the past directly affects current utility (or, indirectly through productivity in the nonmarket sector).

This paper analyzes a monopolist that markets successive generations of new and improving nondurable products. Prices, research intensity, and product innovations are derived as sequential equilibrium outcomes to a dynamic game with incomplete information. Asymmetric information is an important feature of the model. The monopolist is fully aware of the current product's quality, as are consumers who have tried it. However, the beliefs of other people are characterized by a probability distribution that depends on the monopolist's marketing strategy and the product's popularity. The analysis illustrates a new context in which price signaling might serve as a mechanism for ensuring that only high-quality products are marketed. More important, it shows how product life cycles are generated in the absence of signaling and how a reputation for producing high-quality goods becomes established in such cases.

This paper presents a model of job matching the generalizes the existing literature by allowing for different jobs types, or occupations. Such differences affect the value of job-specific experience, inducing a career profile where certain types are sampled before others. More specifically, the analysis shows that it is optimal for the young and inexperienced to gravitate toward jobs exhibiting a certain kind of risk. Then, after deriving the equilibrium job turnover rate for an economy in which people do not switch occupations, panel data are used to estimate its underlying parameters. The hypothesis that people do not switch occupations is rejected against the alternative that they do, thus providing empirical support for the theoretical extension undertaken here.

The bank financial management process involves assets, liabilities, and factors external to the bank and thus is multivariate. Because variables such as deposits, loans, or interest rates are often related with a time lag to another variable such as investments, the process is also dynamic. Although the research work of Aigner [1], Aigner and Bryan [2], Anderson and Burger [3], Bryan [6], Bryan and Carleton [7], Fraser and Rose [10], Hester and Pierce [13], and Melnik [14] has dealt with the multivariate aspect of the process, the consideration of dynamic properties in empirical work has been limited.

This paper is an empirical investigation of equilibrium restrictions on household consumption and male labor supply. It exploits a simple factor structure, rationalized by two assumptions, that household allocations are Pareto optimal and that the labor market is competitive. The paper estimates household preferences, and tests how well this parsimonious factor structure represents panel data on married couples and time series data on asset returns. Most of the estimates are roughly comparable to those found in previous work; no evidence against the simple factor representation is found and the intertemporal capital asset pricing model is not rejected.

We develop a pure moral hazard model, and a closely related hybrid one, where there are both hidden actions and hidden information, to derive the restrictions from optimal contract theory that characterize set identification. In pure moral hazard models, the expected utility of managers is equalized across states, whereas in a hybrid model the optimal contract equates the expected utility of truth telling with the expected utility of lying. These restrictions are testable. Our identi…cation analysis establishes sharp and tight bounds on the identified set. Our tests and estimators are based on these bounds. We apply semiparametric methods to test the models, estimate the structural parameters, and quantify the effects of hidden actions versus hidden information. The pure moral hazard model is rejected on a large panel data set measuring the compensation of chief executive officers and the …financial and accounting returns of the publicly traded …firms they manage. We do not, however, reject the restrictions of the hybrid model, and our structural estimates for that model show the degree of private information varies considerably across sectors and over fi…rm size.

Fewer women than men become executive managers. They earn less over their careers, hold more junior positions, and exit the occupation at a faster rate. We compiled a large panel data set on executives and formed a career hierarchy to analyze mobility and compensation. We find, controlling for executive rank and background, that women earn higher compensation than men, experience more income uncertainty, and are promoted more quickly. Among survivors, being female increases the chance of becoming chief executive officer. The unconditional gender pay gap and job-rank differences are primarily attributable to female executives exiting the occupation at higher rates than men.

We provide empirical restrictions of a model of optimal order submissions in a limit order market. A trader's optimal order submission depends on the trader's valuation for the asset and the trade-offs between order prices, execution probabilities and picking off risks. The optimal order submission strategy is a monotone function of a trader's valuation for the asset. We test the monotonicity restriction in a sample of order submissions and their realized outcomes from the Stockholm Stock Exchange. We do not reject the monotonicity restriction for buy orders or sell orders considered separately, but reject the monotonicity restriction for buy and sell orders considered jointly.
