Ecological-economic modeling of pollination complexity and pesticide use in agricultural crops

Journal of Bioeconomics - Recent years have witnessed a substantial decline of both managed and wild bees in Europe due to the increase of pesticides use. Hence, many European agricultural systems...     

Hercules and Penrose

Penrose's The Theory of the Growth of the Firm is one of mostimportant modern contributions to the theory of the firm. Inthis paper we are concerned with her analysis of the HerculesPowder Company published separately in Business History Review.The Hercules paper is important because it provides a uniquecase analysis of Penrosean growth processes, and indeed becausethere is reason to believe that it may have had a strong influenceon the development of the book itself. Since Hercules is stilloperating today, it also constitutes an interesting living laboratorythat may allow us to explore whether it has continued to pursuePenrosean growth processes over the intervening years.     

Quantifying Price Liberalization in Russia

We seek to quantify the success of Russia's attempt to achieve price-liberalization initiatives as part of the reforms established under the Big Bang of January 1992. We do so by studying the time-series behavior of commodity prices between 1992–1995 and focusing on the relationship between the behavior of prices of similar goods within and across cities. We supplement this analysis by examining city-level surveys that seek to quantify the extent to which firms are currently able to set and adjust commodity prices in accordance with market conditions. Our evidence suggests that price liberalization gradually gained momentum following the Big Bang and that prices generally reflected market conditions by the first quarter of 1995. However, regional pockets of resistance to price-reform efforts continue to persist, indicating that Russia has yet to achieve full market integration.J. Comp.

The demand for money during a period of inflationary expectations. Some FIML based estimates for Greece

This paper estimates and tests a model of the demand for money function, which uses the public's expectations of future inflation as a proxy of the opportunity cost of holding money. The hallmark of the paper is that expectations are rational inMuth sense. The cross-equation rational expectations restrictions are derived and then tested, using quarterly Greek data of the high inflation period 1973I to 1981 IV. The paper concludes that the evidence is consistent with the rational expectations assumption and supports the adopted specification of the money demand function.     

Under the AEGIS of knowledge-intensive entrepreneurship: employment growth and gender of founders among European firms

An increasing number of theoretical and empirical analyses address the role of innovation as one of the main sources of firm growth. More recently, studies have looked at the role of gender diversity as a possible determinant of innovation and entrepreneurial performance. However, the relationship between gender and employment growth—a dimension of entrepreneurial performance—still remains unexplored to a large degree. This paper contributes to the empirical literature on gender and entrepreneurial performance in several ways. First, it examines the role played by both innovation and gender ownership as determinants of employment growth rates of young, knowledge-intensive entrepreneurial (KIE) firms. Second, it investigates the indirect impact of contributing factors—such as the characteristics of the market, knowledge-based capital, and human capital—on employment growth. And third, it relies on a rich new cross-sectional data set on young, KIE firms across European Union (EU) countries. The data set contains information not only on the gender of the firm’s founders but also on the market environment, business strategy, and innovative and economic performance of firms.
