We survey the microfoundations, empirical evidence and estimation issues underlying the aggregate matching function. Several microeconomic matching mechanisms have been suggested in the literature with some successes but none is generally accepted as superior to all others. Instead, an aggregate...

GARCH option pricing models have the advantage of a well-established econometric foundation. However, multiple states need to be introduced as single state GARCH and even Levy processes are unable to explain the term structure of the moments of financial data. We show that the continuous time...

The predictability of Finnish stock returns is studied using the framework of Ferson and Harvey (1993). We use a conditional asset pricing model where risk premia and risk sensitivities are conditioned on a range of financial information variables. In particular, we study the effect of the...

The efficiency of a market is challenged when price dispersion occurs. Previous studies focused on non-durable consumption goods. This study extends the analysis to the case of residential property, whose transactions are dominated by a second-hand market with many potential buyers and sellers....

Existing models of equilibrium unemployment with endogenous labor market participation are complex, generate procyclical unemployment rates and cannot match unemployment variability relative to GDP. We embed endogenous participation in a simple, tractable job market matching model, show...
