Temporary Separations and Firm Size in the German Labour Market

We estimate the duration of out-of-work periods in the German labour market from 1980–90 and their relationship with employment protection legislation. We distinguish between Employment Interruptions that are legally protected and ordinary Layoffs. We investigate the question of whether the size of employer has an impact on the choice of the type of temporary separation. We find that firm size does matter, in both the type and the duration of temporary separations, and we examine the complex re-hiring process.     

The effect of raising deposit insurance coverage in times of financial crisis – Evidence from Croatian microdata

Typically, depositors in transition countries react very sensitively to the safety of deposits. Faced with rising deposit outflows in October 2008, many transition countries were forced to extend the limits of deposit insurance coverage. Has this calmed private agents? Or has it caused more uncertainty? We analyze these questions by employing household survey data for Croatia from exactly the time deposit insurance was extended. First, we provide evidence how the financial crisis has affected trust in banks and trust in the local currency. Then, we show that the increase in deposit insurance coverage had an immediate and positive impact on how people perceived the safety of deposits and the credibility of the local currency. Therefore, our results suggest that this policy measure helped to prevent a more serious and dangerous meltdown of deposits and a further shift towards foreign currency denominated assets. However, despite this effect the perceived safety of deposits remained lower than it was before the financial crisis. We also consider this finding to be of relevance for other countries of Central, Eastern and Southeastern Europe.     

The euro and its consequences: What makes a currency strong?

The creation of the Economic and Monetary Union (EMU) and the introduction of the euro was one of the great events in economic history after World War II. The basic attractiveness of the euro is its large and expanding transaction size and the independent central bank which pursues price stability as its primary goal. The basic strength of the dollar is the hysteresis effect based on economies of scale and network externalities. The conclusion in the paper is that at present the hysteresis effect dominates the sheer size effect and the dollar remains the key vehicle currency while the euro has established itself as the second most widely used currency in the world. The euro depreciated against the dollar in the first three years after its introduction. In the paper the euro weakness is explained by the positive growth differential in favor of the U.S. economy caused by the advance in IC-technology and a pick-up in total factor productivity. In the medium run, the outlook for the euro is favorable. The U.S. current account deficit is unsustainable and improvements require a substantial depreciation of the dollar.Distinguished Address presented at the Fifty-Fourth International Atlantic Economic Conference, Washington D.C., October 10–13, 2002.     

Delegation and incentives

This article analyzes the relation between authority and incentives. It extends the standard principal‐agent model by a project selection stage in which the principal can either delegate the choice of project to the agent or keep the authority. The agent's subsequent choice of effort depends both on monetary incentives and the selected project. We find that the consideration of effort incentives makes the principal less likely to delegate the authority over projects to the agent. In fact, if the agent is protected by limited liability, delegation is never optimal.     

Exports and Productivity Growth: First Evidence from a Continuous Treatment Approach

A recent survey of 54 micro-econometric studies reveals that exporting firms are more productive than non-exporters. However, previous empirical studies show that exporting does not necessarily improve productivity. One possible reason for this result is that most previous studies are restricted to analysing the relationship between a firm’s export status and the growth of its labour productivity, using the firms’ export status as a binary treatment variable and comparing the performance of exporting and non-exporting firms. In this paper, we apply the newly developed generalised propensity score (GPS) methodology that allows for continuous treatment, that is, different levels of the firms’ export activities. Using the GPS method and a large panel data set for German manufacturing firms, we estimate the relationship between a firm’s export-sales ratio and its labour productivity growth rate. We find that there is a causal effect of firms’ export activities on labour productivity growth. However, exporting improves labour productivity growth only within a sub-interval of the range of firms’ export-sales ratios. JEL no.  F14, F23, L60     

Die Agenda — ein Konstrukt des Rezipienten?

The objective of this study is to integrate schema theory into the agenda-setting model. We examined the influence of cognitive schemas on the perception of political issues presented in the media. We used a multi-method-design to scrutinize 25 young adults’ perception of the television debates between chancellor Schröder and his challenger during the 2002 German election campaign. Before the debates took place, participants were interviewed, using a standardized questionnaire. After having watched the debates in familiar surroundings, participants were asked to reproduce the discussed issues by a non-standardized, open questionnaire. Additionally, the debates were analyzed and the issues discussed were ranked. Results indicate that recipients pay more attention to political issues already clearly anchored in their issue schemas, and remember those issues better than others. Our results underline that a further inclusion of schema theory into the agenda-setting model is necessary to better reconstruct the process of political information processing.     

How Do Debit Cards Affect Cash Demand? Survey Data Evidence

This paper analyzes how EFT-POS payments and ATM withdrawals affect cash demand. In particular, survey data about Austrian individuals are employed to estimate a purse cash demand equation, which takes account of sample selection effects. The results reveal that purse cash demand is significantly and sizably affected by debit card usage and that there are significant differences in cash demand for individuals with different debit card usage frequencies. In addition, the effect of EFT-POS payments on cash use at the point-of-sale is discussed on the basis of data from a consumer transaction survey.     

A web-based system architecture for ontology-based data integration in the domain of IT benchmarking

In the domain of IT benchmarking (ITBM), a variety of data and information are collected. Although these data serve as the basis for business analyses, no unified semantic representation of such data yet exists. Consequently, data analysis across different distributed data sets and different benchmarks is almost impossible. This paper presents a system architecture and prototypical implementation for an integrated data management of distributed databases based on a domain-specific ontology. To preserve the semantic meaning of the data, the ITBM ontology is linked to data sources and functions as the central concept for database access. Thus, additional databases can be integrated by linking them to this domain-specific ontology and are directly available for further business analyses. Moreover, the web-based system supports the process of mapping ontology concepts to external databases by introducing a semi-automatic mapping recommender and by visualizing possible mapping candidates. The system also provides a natural language interface to easily query linked databases. The expected result of this ontology-based approach of knowledge representation and data access is an increase in knowledge and data sharing in this domain, which will enhance existing business analysis methods.

On the different “worlds” of intra-organizational knowledge management: Understanding idiosyncratic variation in MNC cross-site knowledge-sharing practices

This qualitative field study investigated cross-site knowledge sharing in a small sample of multinational corporations in three different MNC business contexts (global, multidomestic, transnational). The results disclose heterogeneous “worlds” of MNC knowledge sharing, ultimately raising the question as to whether the whole concept of MNC knowledge sharing covers a sufficiently unitary phenomenon to be meaningful. We derive a non-exhaustive typology of MNC knowledge-sharing practices: self-organizing knowledge sharing, technocratic knowledge sharing, and best practice knowledge sharing. Despite its limitations, this typology helps to elucidate a number of issues, including the latent conflict between two disparate theories of MNC knowledge sharing, namely “sender–receiver” and “social learning” theories (Noorderhaven & Harzing, 2009). More generally, we develop the term “knowledge contextualization” to highlight the way that firm-specific organizational features pre-define which knowledge is considered to be of special relevance for intra-organizational sharing.
