The option pricing model has been the work horse in the development of financial economics ever since the seminal papers by Black and Scholes (1973) and Merton (1973). Here, the arbitrage free prices of equity options were derived in closed form. Apart from the price of the underlying asset and contractual terms (strike

Statistical analysis of the job-search model has isolated the role played by the minimum observed wage in identifying and estimating behavioral parameters. Estimators based on order statistics, however, are influenced by measurement error in ways that estimators based on averages are not, and there is ample evidence that wage data contain measurement errors. We propose a model in which worker behavior is captured by the prototypal search model but wages are observed with error.

Recent empirical evidence demonstrates the presence of an important long-memory component in realized asset return volatility. We specify and estimate multivariate models for the joint dynamics of stock returns and volatility that allow for long memory in volatility without imposing this property on returns. Asset pricing theory imposes testable cross-equation restrictions on the system that are not rejected in our preferred specifications, which include a strong financial leverage effect. We show that the impact of volatility shocks on stock prices is small and short lived, in spite of a positive risk-return tradeoff and long memory in volatility.

The article structually estimates an on‐the‐job search model of job separations. Given each employer pays observably equivalent workers the same but wages are dispersed across employers, an employer's separation flow is the sum of an exogenous outflow unrelated to the wage and a job‐to‐job flow that decreases with the employer's wage. Using data from the Danish Integrated Database for Labour Market Research, the empirical results imply, as predicted by theory, that search effort declines with the wage. Furthermore, the estimates explain the employment effect, defined as the horizontal difference between the distribution of wages earned and the wage offer distribution.
