Ist die Katharsis-Theorie zu retten?

Catharsis theory is regarded as refuted. This widespread belief can be questioned for two reasons. First, most test films used in experimental studies do not meet the requirements of catharsis theory; second the social consequences of catharsis were not measured. Two films were produced for our experiment, one which meets the requirements of catharsis theory and should reduce aggressiveness and one which, according to alternative theories, should increase aggressiveness. A control group saw a neutral film. As dependent variables (a) level of general aggression, (b) aggressive inclinations in social situations, and (c) willingness to use aggressive stereotypes were measured. The film that was assumed to reduce aggressiveness increased aggressiveness even more than the film that was assumed to increase it. This surprising finding and its consequences are discussed.     

An Examination of Entry and Competitive Performance in Rural Banking Markets

This article explores the change in the level of competition in rural banking markets after the deregulation that occurred following passage of the Riegle‐Neal Act of 1994. Using an empirical model that utilizes both the number of banks and the value of deposits in a cross‐section of 278 rural markets, we decompose the impact of the entry of new banks into resulting changes in per capita demand and the costs/profits of local banks in 1994 and 2004. The results support the view that local banking markets have become more competitive since the mid‐1990s.     

Do international shocks affect small wholesalers and retailers?

Previous research has suggested that the smallest firms are those most vulnerable to international competition, as measured by exchange rate fluctuations and import shares. However, that work—and the overwhelming bulk of the empirical literature on determinants of exit or firm survival—dealt entirely with the manufacturing sector of the economy. This paper analyzes annual US data for 1989–2005 for about 50 wholesale and retail sectors to explain small firm exit rates in several employment size categories. The main result is that wholesalers respond negatively to a stronger currency in a manner similar to that of manufacturers, while retailers are generally unaffected.     

International Rent Sharing and Domestic Labour Markets: A Macroeconomic Analysis

Compared to international trade relations relatively little is known about the role foreign direct investment linkages play in the transmission of disturbances from one country to the next. Inspired by the microevidence on profit sharing within multinational corporations and within industries, we investigate for six countries whether a cross-border rent-sharing phenomenon can be identified at the macroeconomic level. The rent-sharing hypothesis implies that an increase in foreign profitability should boost wages and/or employment in the domestic economy. We find corroborative evidence for Belgium, France, Germany, the Netherlands and the United Kingdom. US labour market conditions, by contrast, are not affected by changes in profitability in other countries. JEL no. E32, F23, F40, J23, J31     

On the relationship between migration and fertility

The relationship between migration and fertility is examined. The author proposes an alternative model to those used previously and applies it to data from the 1973 National Demographic Survey of the Philippines. The model assumes that although the fertility of migrants declines initially because of economic and psychological hardships, it rises subsequently as migrants become settled in their new environment.     

Prospects for international maritime shipping

The world’s energy supplies are dependent not only on the producer countries’ production capacities and policies but also on adequate transport facilities. In fact, a shortage of vessels able to carry coal is widely expected to be a major bottleneck for the substitution of oil by coal on a large scale. Shipowner Peter M. Nomikos holds a different view.     

Smuggling and price disparity

This paper proposes a model of smuggling consistent with the coexistence of smuggling, legal trade and price disparity, defined as a domestic price which exceeds (is less than) the return from legal export (import). These phenomena have been found to characterize Indonesian smuggling. A framework is presented in which legal trade is used to cloak smuggling activity with the implication that the greater the volume of legal trade, the less the costs of smuggling. This model is then used to explain the observation noted above and to show that smuggling may be welfare increasing vis-à-vis the non-smuggling situation, and that even if the suppression of smuggling is costless, tax revenue maximization may require a positive level of smuggling. In addition, the model is applied to coffee and rubber exports from Indonesia.
