Gender Differences in Entrepreneurial Propensity*

Using data from representative population surveys in 17 countries, we find that the lower rate of female business ownership is primarily due to women's lower propensity to start businesses rather than to differences in survival rates across genders. We show that women are less confident in their entrepreneurial skills, have different social networks and exhibit higher fear of failure than men. After controlling for endogeneity, we find that these variables explain a substantial part of the gender gap in entrepreneurial activity. Although, of course, their relative importance varies significantly across countries, these factors appear to have a universal effect.     

The “ugly twins”: Failed low-wage-country sourcing projects and their expensive replacements

International sourcing and sourcing from low-wage countries remain topics of high priority for firms in industrialized countries. Lower factor costs, particularly in low-wage countries, have led to high expectations of savings from both managers and academics. All too often, scientific and particularly practitioner publications present international sourcing as a conditio sine qua non for becoming a (more) successful company. However, research has shown that these extensive savings do not materialize automatically, particularly when sourcing customer-specific items, such as automotive components. This paper analyzes the operational and financial implications and real effects of cost-oriented sourcing from China, based on the specific example of a European automotive OEM. Furthermore, it sheds light on the ambivalent and often overrated savings impact of sourcing from low-wage countries. Our analysis of a comprehensive set of secondary data from a company data warehouse reveals that more than three quarters of the analyzed China-sourcing projects do not reap the expected benefits. Moreover, each failed low-wage-country sourcing project has its so-called “ugly twin”, the need to resort back to suppliers from high-wage countries at a higher cost. Implications for managerial practice include the suggestion to employ extended calculation methods, entailing influence factors other than from procurement, particularly for low-wage-country sourcing. Furthermore, we recommend creating an awareness of potentially biased decision-making among purchasing personnel who follow standard industry recipes.     

Existence of valuation equilibria when equilibrium strategies cannot differentiate between equal ties

This paper reconsiders the valuation equilibrium concept (Jehiel and Samet, 2007) and proposes an additional regularity condition concerning the players? equilibrium strategies. The condition, which requires equilibrium strategies to induce the same local behaviour at all nodes with “similar” optimal actions, increases both the predictive power and the internal consistency of the concept — especially when used as a tool to study boundedly rational behaviour in games with imperfect information and/or imperfect recall. It is shown not to conflict with existence.     

On the speed and boundaries of structural adjustment when fiscal policy is tight

Governments of transition economies are subject to fiscal constraints (e.g. credit constraints). However, exaggerated fiscal discipline might feed into the structural adjustment process. The government designs and times the privatisation programme, yet may find itself in a fiscal squeeze because restructuring moves costs from firms to the public budget. This paper models this problem in a simple dynamic set-up. Several distinct reform strategies, which differ in the speed and level of structural adjustment, are identified. Tight fiscal discipline in early stages of transition may delay or halt privatisation. A different sequencing of policy or different taxation, benefits, and privatisation sales rules, can rectify this problem.     

A model of money with multilateral matching

We develop a model of decentralized monetary exchange to examine the distributional effects of inflation across heterogeneous agents. The agents have private information about their productivity, preferences, or money holdings. Matching is multilateral and each seller is visited by a stochastic number of buyers. The good is allocated according to a second-price auction in money. In equilibrium, homogeneous buyers hold different amounts of money leading to price dispersion. We find the closed-form solution for the distribution of money holdings. Entry of sellers is suboptimal except at the Friedman rule. Inflation acts as a regressive tax.     

Der deutsche Strommarkt im Umbruch: Zur Notwendigkeit einer Marktordnung aus einem Guss

The German electricity market is changing fundamentally as renewable energy replaces conventional sources. Simultaneously, regional imbalances between generation and consumption are appearing. The authors sketch a new market design for the German electricity market, jointly taking into account the efficient expansion of renewables and the grid’s stability. A premium paid in addition to the spot market price promotes renewable electricity. Furthermore, they propose to split the German electricity market into a small number of price zones to cope with insufficient transmission capacities. By systematically strengthening regional and temporal price signals, the authors expect a notable cost reduction of the energy transition to be achieved.     

On the Private Provision of Intertemporal Public Goods with Stock Effects

The provision of public goods is often hindered by a lack of powerful institutions that can sanction free riders or otherwise enforce private contributions to the public good. The simple deposit based solution introduced by Gerber and Wichardt (J Public Econ 93:429–439, 2009) solves this problem, but may require prohibitively large deposits, in particular in the context of intertemporal public goods. In this paper, we propose a modification of the deposit solution that relies only on comparably small deposits. The proposed modification improves the applicability of the procedure, most notably as it also allows to reduce deposits in static public goods problem by transforming them into dynamic ones with small per period contributions.     

What do we know about real exchange rate nonlinearities?

Nonlinear modeling of adjustments to purchasing power parity has recently gained much attention. However, a huge body of the empirical literature applies ESTAR models and neglects the existence of other competing nonlinear models. Among these, the Markov Switching AR model has a strong substantiation in international finance. Our contribution to the literature is fivefold: First, ESTAR and MSAR models from a unit root perspective are compared. To this end, a new unit root test against MSAR is proposed as the second contribution. Thirdly, the case of misspecified alternatives in a Monte Carlo setup with real world parameter constellations is studied. The ESTAR unit root test is not indicative, while the MSAR unit test is robust. Fourthly, the case of correctly specified alternatives is considered and low power of the ESTAR but not for the MSAR unit root test is observed. Fifthly, an empirical application to real exchange rates suggests that they may indeed be explained by Markov Switching dynamics rather than ESTAR.     

Fiscal Consolidations in the Central and Eastern European Countries

We study fiscal consolidations in the Central and Eastern European countries and what determines the probability of their success. We define consolidation events as substantive improvements in fiscal balances adjusting for the impact of cyclical effects. We use logit models for the period 1991–2003 to assess the determinants of the success of a fiscal adjustment. The results seem to suggest that for these countries expenditure based consolidations have tended to be more successful. By contrast, revenue-based consolidations have a tendency to be less successful. JEL no. C25, E62, H62
