Public expenditure, international specialisation and agglomeration

It is widely recognised that public-sector purchasers tend to favour domestic suppliers. We study the consequences of such home-biased public procurement on international specialisation. Using a general-equilibrium model with a monopolistically competitive sector, we find that a country will specialise in that sector if it has relatively large home-biased procurement (the “pull” effect). Furthermore, home-biased procurement can counter agglomeration forces in that sector and thereby attenuate the overall degree of international specialisation (the “spread” effect). Our empirical analysis, conducted on input-output data for the European Union, yields supporting evidence for the pull effect and some support for the spread effect.     

Social Security,Unemployment, and Growth

The paper develops an overlapping generations model that highlights interactions between social security, unemployment and growth. The social security system has two components: old age pensions and unemployment insurance. Pensions have a direct effect on economic growth. Both pensions and unemployment benefits influence equilibrium unemployment caused by wage bargaining. Since unemployment deteriorates growth, both types of social security have an indirect negative effect on growth.JEL Code: E24, H55, J51     

News Shocks in the Data: Olympic Games and Their Macroeconomic Effects

We examine the macroeconomic effects of bidding for the Olympic Games using panel data for 188 countries during the period 1950–2009. Our findings confirm that economies react to news shocks: investment, consumption, and output significantly increase 9 to 7 years before the actual event in bidding countries. Hosting countries also experience significant increases in investment, consumption, and output 5 to 2 years before the hosting of the Games. Mapping the Olympics into a macroeconomic model, we show that we can match our empirical findings if we assume that an Olympic bid represents news about increases in government investment.     

Network Support and the Success of Newly Founded Business

The "network approach to entrepreneurship" is a prominent theoretical perspective within the literature on entrepreneurship. This literature assumes that network resources, networking activities and network support are heavily used to establish new firms (network founding hypothesis). Further, those entrepreneurs, who can refer to a broad and diverse social network and who receive much support from their network are more successful (network success hypothesis). Based on a study of 1,700 new business ventures in Upper Bavaria (Germany), the article gives an empirical test of the network success hypothesis. It is argued that one reason, why previous studies did not consistently find positive network effects, may be that social capital (network support) is used to compensate shortfalls of other types of capital (human capital and financial capital). This compensation hypothesis, however, does not find empirical confirmation. On the other hand, however, the network success hypothesis proves to be valid in our analyses, i.e. network support increases the probability of survival and growth of newly founded businesses.
