African elephants: the effect of property rights and political stability

African elephant populations have declined by more than 50% over the past 20 years. International outrage over the slaughter led to a worldwide ban on ivory sales beginning in 1989, despite the objections of many economists and scientists, and of several southern African countries that have established systems of property rights over elephants. Far from declining, elephant populations in many of these countries have increased to levels at or above the carrying capacity of the ecosystem. This article estimates the determinants of changes in elephant populations in 35 African countries over several time periods. The authors find that, controlling for other factors, countries with property rights systems of community wildlife programs have more rapid elephant population growth rates than do those countries that do not. Political instability and the absence of representative governments significantly lower elephant growth rates.     

Smoking laws and their differential effects on restaurants, bars, and taverns

This article examines the effect of restrictive smoking laws on restaurants, bars, and taverns. Supporters of these laws often argue that they do not harm firms and may even raise profits. Opponents argue that owners cater to customer smoking preferences, and laws mandating specific policies will negatively impact profits. This article provides a framework for examining the distribution of effects that smoking laws exert on businesses, and demonstrates that changes in total sales or tax revenues do not provide a meaningful understanding of the economic implications because smoking laws exert different effects on different firms. The distribution of these effects is examined using data from a nationwide survey of 1,300 restaurant, bar, and tavern owners. While some subsets of firms are predicted to suffer revenue declines, bars are predicted to be more than twice as likely to experience losses as restaurants. An important implication is that the increasing level of governmental restrictions on smoking in the hospitality sector could gradually impact the types of service available to the public.     

Were Modern Capital Structure Theories Valid in Belgium Before World War I?

Abstract:  This study investigates whether modern theories can explain capital structure in a historical environment which was characterized by poor investor protection, booming stock markets and strong banks, and in which taxes did not affect leverage. Our results, based on a unique, hand-collected sample of 556 firm-year observations for 129 listed companies in Belgium before World War I, are remarkably similar to findings for present-day samples. Leverage was positively related to asset tangibility, firm size and firm age, and it was negatively related to profitability and prior stock returns. Bank relationships were associated with lower leverage.     

Transactions, volume, and volatility

We show that the positive volatility-volume relation documentedby numerous researchers actually reflects the positive relationbetween volatility and the number of transactions. Thus, itis the occurrence of transactions per se, and not their size,that generates volatility; trade size has no information beyondthat contained in the frequency of transactions. Our resultssuggest that theoretical research needs to entertain scenariosin which (i) both the frequency and size of trades are endogenouslydetermined, yet (ii) the size of trades has no information contentbeyond that contained in the number of transactions.     

Do universal banks create value? Universal bank affiliation and company performance in Belgium, 1905-1909

We investigate the impact of universal bank relations on the performance and the risk of listed companies in Belgium in the period 1905-1909. Our results are consistent with the view that universal banks are efficient institutions which overcome problems of asymmetric association inevitably associated with external finance. We find that universal bank affiliation was positively linked with market-to-book ratio and return-on-assets. Performance was also positively related to the degree of bank involvement. Universal bank relations were significant and negatively correlated with volatility of return-on-assets. Finally, stock return performance, measured by the Sharpe ratio, was also significantly better for affiliated corporations.
