Extrapair fertilizations (EPFs) are frequently documented in songbirds; however, the extent to which this reproductive tactic contributes to variance in male reproductive success and hence the strength of sexual selection on males remains little studied. Using 2 approaches, intraspecific and...

This article uses the European Patent Office Worldwide Patent Statistical Database to examine the geographic distribution and global diffusion of inventions in thirteen climate-mitigation technologies since 1978. The data suggest that until 1990 innovation was driven mostly by energy prices....

Recent studies of search theory examine how employers use a wage-setting mechanism - either by bargaining or through the posting of a non-negotiable wage offer in a job ad - to facilitate search. We contribute to this literature by examining wage posting in job ads in the US, the UK, and...

An analysis of US and Slovenian vacancy data sets reveals that an employer who is searching to fill a job vacancy is more likely to fill the vacancy by hiring an under-qualified worker when the search costs are higher; when, at the start of the search, the employer has less time to search at low...

The article attempts to quantify determinants influencing the dynamics of employment decisions on agricultural holdings in Slovenia and to test specific aspects of labor reallocation during the transition period by the application of an agricultural household model. Through the use of a...

Goodness-of-fit tests are proposed for the skew-normal law in arbitrary dimension. In the bivariate case the proposed tests utilize the fact that the moment-generating function of the skew-normal variable is quite simple and satisfies a partial differential equation of the first order. This...

In a stochastic volatility model, the no-free-lunch assumption does not induce a unique arbitrage price because of market incompleteness. In this paper, we consider a contingent claim on the primitive asset, traded in zero net supply. Given a system of Arrow-Debreu state prices, we provide...

The paper investigates places of residential segregation and separation in Czech cities and discusses them in the context of new socio-spatial divisions that are emerging in the context of post-socialist transformations in the Czech Republic. It is argued that in post-socialist countries, where...
