Energy for the future

The Eleventh World Energy Conference 1980 was held in Munich from the 8th to the 12th of September. “Looking ahead to 2020”—the title of the energy survey published for this conference—indicates that the long-term trend was in the centre of interest. Oil is a finite resource and has to be substituted in the long run. It is the period in between which causes much concern because during this time we cannot do without oil. It is against this background that we have asked Senator Wolfgang Oehme, chairman of the board of Esso A.G., to present to us his views on this critical period of time.

Effort maximization in asymmetric contest games with heterogeneous contestants

Contest rules are set up by administrators who frequently have discretionary power in specifying the details of these rules, i.e., they can bias the contest rules toward specific contestants in order to further their prime objective. We derive the optimal bias of the contest rule for a contest administrator, who is interested in maximizing the total efforts expended in the contest. The solution is obtained in closed form for a widely used class of n-person contest games. Setting the optimal bias has important implications: (i) there is never exclusion of strong players, instead there is (endogenously induced) inclusion of weak contestants; (ii) the contest administrator will optimally level the playing field by encouraging weak contestants, but he will not equalize the contestants’ chances unless they are identical; and (iii) at least three contestants will be active in equilibrium of the optimal contest, irrespective of heterogeneity.     

Labour‐market institutions and their impact on trade partners: A quantitative analysis

Recent theoretical literature studies how labour market reforms in one country can affect labour market outcomes in other countries, thereby rationalizing widely held policy beliefs and empirical evidence. But what is the quantitative relevance of such spillover effects? This paper combines two recent workhorse models: the canonical search‐and‐matching framework and the heterogeneous firms international trade model. Qualitatively, the framework confirms that labour market reforms in one country benefit its trading partners, replicating the stylized facts. However, when wages are bargained flexibly, the model quantitatively underestimates the correlation of structural unemployment rates across countries. Introducing some degree of real wage rigidity remedies this problem.     

Two implications of habit formation for international trade

A country's choice set of trade policies becomes very constrained when its consumers are subject to habit formation. Free trade may, in fact, lie outside the choice set. Furthermore, the rise in import elasticities' values over time can be attributed to habit formation.     

Assessing the employment effects of the German welfare reform – an integrated CGE-microsimulation approach

The purpose of this article is to quantify the employment effects of the recent German welfare reform. The key element of this reform was to merge the coexisting transfer systems Social Assistance (SA) and Unemployment Assistance (UA) into one unified benefit (Arbeitslosengeld II – ALG II). We also consider a second reform scenario that is intended to further improve the labour supply incentives of low-skilled workers. Our methodological contribution is to use an integrated CGE-microsimulation model. In adopting such an approach, we are able to combine the advantages of microsimulation studies by accounting for the large amount of heterogeneity in terms of households’ preferences and budget constraints with the advantages of an applied general equilibrium model. The latter permits us to identify potential general equilibrium repercussions through changes in wages and unemployment. The simulations indicate that the introduction of ALG II results in a negligible increase in employment of only 45?000 individuals. In contrast, a cut in benefit levels combined with a decrease in transfer withdrawal is shown to produce somewhat larger employment effects of about 190?000 individuals.     

On the determinants of household debt maturity choice

This article jointly analyses a behavioural and a cultural concept to explain household debt portfolio choice. The behavioural approach explores the role of time preferences on household debt maturity in a theoretical model and a numerical analysis. We derive a positive relationship between the long-term discount factor δ and the optimal maturity of household loans. The cultural approach examines whether national culture is a reasonable predictor for household debt maturity. We show that culture is an important factor for households’ borrowing decisions and has even more predictive power than time preferences. Countries with higher scores on the Hofstede dimension of long-term orientation tend to have shorter household debt maturity. Time preferences incur a primarily mediating role, because the effect of national culture on the borrowing decision is reduced, as the long-term discount factor δ increases.     

Advancing into the 21st Century: Visions and Challenges Facing the Downunder Economy

Long-term visions serve to focus on essentials for sustained economic and social welfare. We now have to face up to the challenge of globalisation (growing international capital mobility), at a time when we are undoing our historic, self-imposed protectionism. This also creates new opportunities, in particular in the dynamic Asia-Pacific economies.
There still is a 'window of opportunity' before an aging population will become a dominant problem. In the next 25 years, business will have to cope with high real interest rates and major uncertainties that now surround environmental policies.
If we are to take on these challenges in constructive and beneficial ways, we have to develop an institutional order that enables the utilisation of knowledge by enterprising people. This requires a simple, transparent and reliable legal and regulatory framework, which supports competitive market processes, and the defence of openness to international trade and capital flows against particular interest groups.
It seems plausible that the Downunder economy can grow over the next 25 years at about 3.5 per cent per capita if the right institutional conditions are created. If we fail to do so, a growing share of the capital, the skills and the enterprise made Down-under will move to offshore locations which encourage a better use of knowledge and capital by enterprising people. This would deprive many of economic opportunity. The central challenge therefore is to develop a system of government and labour relations which makes the Downunder economy internationally attractive.
