Monopsonistic Labour Markets and the Gender Pay Gap: Theory and Empirical Evidence
Boris Hirsch
Lecture Notes in Economics and Mathematical Systems,
Nr. 639,
2010
Abstract
This book investigates models of spatial and dynamic monopsony and their application to the persistent empirical regularity of the gender pay gap. Theoretically, the main conclusion is that employers possess more monopsony power over their female employees if women are less driven by pecuniary considerations in their choice of employers than men. Employers may exploit this to increase their profits at the detriment of women’s wages. Empirically, it is indeed found that women’s labour supply to the firm is less wage-elastic than men’s and that at least a third of the gender pay gap in the data investigated may result from employers engaging in monopsonistic discrimination. Therefore, a monopsonistic approach to gender discrimination in the labour market clearly contributes to the economic understanding of the gender pay gap. It not only provides an intuitively appealing explanation of the gap from standard economic reasoning, but it is also corroborated by empirical observation.

Openness and Income Disparities: Does Trade Explain The 'Mezzogiorno' Effect?
Claudia M. Buch, P. Monti
Review of World Economics,
Nr. 4,
2010
Abstract
We use Italian regional data to answer the question whether trade affects within-country income differentials. In Italy, the more affluent Northern regions trade more with the rest of the world than the poorer ones in the Southern “Mezzogiorno” regions. Prima facie, there is a positive correlation between external trade and per capita income. Studying this relationship empirically requires taking into account the endogenous component of trade. We argue that panel cointegration models can complement instrumental variables techniques to account for the endogeneity of trade in a panel context. Both methods show a positive link between trade openness and the level of income per capita.

Margins of international banking: Is there a productivity pecking order in banking, too?
Claudia M. Buch
Bundesbank Discussion Paper 12/2009,
2009
Abstract
Modern trade theory emphasizes firm-level productivity differentials to explain
the cross-border activities of non-financial firms. This study tests whether a
productivity pecking order also determines international banking activities. Using
a novel dataset that contains all German banks’ international activities, we
estimate the ordered probability of a presence abroad (extensive margin) and the
volume of international assets (intensive margin). Methodologically, we enrich the
conventional Heckman selection model to account for the self-selection of banks
into different modes of foreign activities using an ordered probit. Four main
findings emerge. First, similar to results for non-financial firms, a productivity
pecking order drives bank internationalization. Second, only a few non-financial
firms engage in international trade, but many banks hold international assets, and
only a few large banks engage in foreign direct investment. Third, in addition to
productivity, risk factors matter for international banking. Fourth, gravity-type
variables have an important impact on international banking activities.

The Gender Pay Gap under Duopsony: Joan Robinson meets Harold Hotelling
Boris Hirsch
Scottish Journal of Political Economy,
Nr. 5,
2009
Abstract
This paper presents an alternative explanation of the gender pay gap resting on a simple Hotelling-style duopsony model of the labour market. Since there are only two employers, equally productive women and men have to commute and face travel cost to do so. We assume that some women have higher travel cost, e.g., due to more domestic responsibilities. Employers exploit that women on average are less inclined to commute and offer lower wages to all women. Since women's firm-level labour supply is for this reason less wage-elastic, this model is in line with Robinson's explanation of wage discrimination.

Organization and Financing of Innovation, and the Choice between Corporate and Independent Venture Capital
Paolo Fulghieri, Merih Sevilir
Journal of Financial and Quantitative Analysis,
Nr. 6,
2009
Abstract
This paper examines the impact of competition on the optimal organization and financing structures in innovation-intensive industries. We show that as an optimal response to competition, firms may choose external organization structures established in collaboration with specialized start-ups where they provide start-up financing from their own resources. As the intensity of the competition to innovate increases, firms move from internal to external organization of projects to increase the speed of product innovation and to obtain a competitive advantage with respect to rival firms in their industry. We also show that as the level of competition increases, firms provide a higher level of financing for externally organized projects in the form of corporate venture capital (CVC). Our results help explain the emergence of organization and financing arrangements such as CVC and strategic alliances, where large established firms organize their projects in collaboration with external specialized firms and provide financing for externally organized projects from their own internal resources.

The Economic Optimality of Sanction Mechanisms in Interorganizational Ego Networks – A Game Theoretical Analysis –
Muhamed Kudic, Marc Banaszak
IWH Discussion Papers,
Nr. 15,
2009
Abstract
Even though small- and medium-sized firms (SMEs) were believed not to proceed beyond exporting in their internationalization routes, we can observe new types of co-operation intensive entrepreneurial firms – so-called “micromultinational enterprises” (mMNEs) – entering the global landscape. These firms face the challenge to manage and control a portfolio of national and international alliances simultaneously (ego network). The aim of this paper is to provide game theoretically consolidated conditions in order to analyze the effectiveness and efficiency of interorganizational sanction mechanisms in an alliance portfolio setting. A game theoretical framework is developed over three stages with increasing complexity. Results show that two out of six analyzed sanction mechanisms do not fulfill the game theoretical condition for effectiveness. The efficiency analysis sensibilizes for discretionary elements in governance structures and demonstrates that not one single sanction mechanism but rather the right choice and combination of different types of sanction mechanisms leads to efficient results. We contribute to the international business, alliance, and network literature in several ways by focusing on alliance portfolios held by mMNEs. In doing so, we move beyond the dyadic level and analyze sanction mechanisms from an ego network perspective, a still widely under-emphasized topic in the literature.

Barriers to Internationalization: Firm-Level Evidence from Germany
Claudia M. Buch
IAW Discussion Paper No. 52,
2009
Abstract
Exporters and multinationals are larger and more productive than their domestic
counterparts. In addition to productivity, financial constraints and labor market
constraints might constitute barriers to entry into foreign markets. We present new
empirical evidence on the extensive and intensive margin of exports and FDI based on detailed micro-level data of German firms. Our paper has three main findings. First, in line with earlier literature, we find a positive impact of firm size and productivity on firms’ international activities. Second, small firms suffer more frequently from financial constraints than bigger firms, but financial conditions have no strong effect on internationalization. Third, labor market constraints constitute a more severe barrier to foreign activities than financial constraints. Being covered by collective bargaining particularly impedes international activities.

Financial constraints and the margins of FDI
Claudia M. Buch
Bundesbank Discussion Paper 29/2009,
2009
Abstract
Recent literature on multinational firms has stressed the importance of low productivity as a barrier to the cross-border expansion of firms. But firms may also need external finance to shoulder the costs of entering foreign markets. We develop a model of multinational firms facing real and financial barriers to foreign direct investment (FDI), and we analyze their impact on the FDI decision (the extensive margin) and foreign affiliate sales (the intensive margin). We provide empirical evidence based on a detailed dataset of German multinationals which contains information on parent-level and affiliate-level financial constraints as well as about the location the foreign affiliates. We find that financial factors constrain firms’ foreign investment decisions, an effect felt in particular by large firms. Financial constraints at the parent level matter for the extensive, but less
so for the intensive margin. For the intensive margin, financial constraints at the affiliate level are relatively more important.

A Multidimensional Evaluation of the Effectiveness of Business Incubators: An application of the PROMETHEE outranking method
Michael Schwartz, Maximilian Göthner
Environment and Planning C: Government and Policy,
2009
Abstract
Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that focused on the effectiveness of incubator initiatives and how to measure incubator performance, there is still a lack of understanding of how to determine incubators that are more effective than others. Based on data from 410 graduate firms, the present article concentrates on this crucial question and compares the long-term effectiveness of five BIs in Germany by applying the multi-criteria outranking technique PROMETHEE. In particular, we investigate whether PROMETHEE is a well suited methodological approach for the evaluation and comparisons in the specific context of business incubation.

Low Skill but High Volatility?
Claudia M. Buch
CESifo Working Paper No. 2665,
2009
Abstract
Globalization may impose a double-burden on low-skilled workers. On the one hand, the relative supply of low-skilled labor increases. This suppresses wages of low-skilled workers and/or increases their unemployment rates. On the other hand, low-skilled workers typically face more limited access to financial markets than high-skilled workers. This limits their ability to smooth shocks to income intertemporally and to share risks across borders. Using cross-country, industry-level data for the years 1970 - 2004, we document how the volatility of hours worked and of wages of workers at different skill levels has changed over time. We develop a stylized theoretical model that is consistent with the empirical evidence, and we test the predictions of the model. Our results show that greater financial globalization and development increases the volatility of employment, and this effect is strongest for low-skilled workers. A higher share of low-skilled employment has a dampening impact.
