Our paper aims to analyze the effectiveness of different risk-sharing mechanisms in providing stability to a monetary union. We select two stylized tools with extreme and opposite features. The first is an expansionary but conventional monetary policy that is used to help EMU’s most fragile member states manage their public debts; the second is a centralized fiscal policy that allows for the transfer of a portion of these public debts from EMU’s most fragile member states to those considered EMU’s “core”. By a stylized periphery-core model of a monetary union, we compare the strengths and weaknesses of these two tools in order to reach some welfare implications in terms of union stability. 相似文献

We apply graphical modelling (GM) theory to identify fiscal policy shocks in SVAR models of the US economy. Unlike other econometric approaches – which achieve identification by relying on potentially contentious a priori assumptions – GM is a data based tool. Our results are in line with Keynesian theoretical models, being also quantitatively similar to those obtained in the recent SVAR literature à la Blanchard and Perotti (2002) , and contrast with neoclassical real business cycle predictions. Stability checks confirm that our findings are not driven by sample selection. 相似文献

In the extensive job search literature, studies assume either sequential or non‐sequential search. This article introduces a novel method to test the hypothesis that firms search sequentially based on the relationship between the number of rejected job applicants and the number of filled vacancies. We distinguish between ten different search methods. For most search methods, including methods that rely on social networks and temporary help agencies, we find that sequential search cannot be rejected. However, when firms use advertising or public/private employment agencies, sequential search is rejected. Hence, we find that both forms of search are relevant for our understanding of the labour market. Further, the form of search is closely related to the search method used. 相似文献

This article investigates the costs of transport regulation using the example of agricultural markets in the US. Using a large database of prices by state of agricultural commodities, we find that dispersion fell for many commodities until the First World War. We demonstrate that this reflected changes in transport costs which in turn in the long run depended on productivity growth in railroads. The year 1920 marked a change in this relationship, however, and between the First and Second World Wars we find considerable disintegration of agricultural markets, ultimately as a consequence of the 1920 Transportation Act. We argue that this benefited railroad companies in the 1920s and workers in the 1930s, and we put forward an estimate of the welfare losses for the consumers of railroad services (that is, agricultural producers and final consumers). 相似文献

In this work we propose a new model for the analysis of telecommunications (Tlc) networks production. This represents an extension of the fund-flow model by Georgescou-Roegen originally applied to the manufacture and agriculture sectors. The adopted framework enables us to describe the functioning of a Tlc network - and the technique underlying the different types of Tlc traffic - by means of a system of multi-production where the production time profile has been clearly defined. One of the most innovative elements of our analysis is the ability to analytically represent the qualitative features of technological options. It also signals new productive options connected to new Tlc services and the introduction of new network facilities. In this way we hope to both further a theoretical understanding of the technological dynamics of the Tlc sector, and provide guidance as to the strategic choices of the economic actors involved. 相似文献

This paper identifies different strategic types of internationalised SMEs, in so doing providing managers and entrepreneurs with a much better understanding of the main strategic options and their relationship with the international performance of firms. We provide a theoretical analysis of strategic orientations and strategic behaviour in international SMEs, followed by an empirical investigation based on a sample of Italian SMEs. The SMEs are grouped into strategic types using cluster analysis, and the link between strategic type and international performance is subsequently analysed using logistic regression. The empirical data suggest that there are four broad strategic types, namely an entrepreneurial/growth-oriented group of firms, a customer-oriented group, a product/inward-oriented cluster, and a further group of firms that lacks strategic orientation. The characteristics of the strategic clusters are discussed, and the regression results show that a clear and proactive strategic orientation and its consistency with business strategy leads to improved international performance. This confirms the positive and highly significant role of strategic types. 相似文献

This paper examines equilibrium trade policies when firms have better information than governments about the profitability of the industry. Contrary to the intuition that the policymakers' lack of information should reduce their incentives to engage in strategic trade intervention, the analysis suggests that information asymmetries may increase trade policy distortions in equilibrium and ultimately worsen the "prisoner's dilemma" between governments. 相似文献

The paper analyzes the relationship between stock prices and fundamentals for a large sample of US stocks in the last 10 years
using a random coefficient model. Heterogeneity and omitted variable bias are properly taken into account with model coefficients
being allowed to vary across time and industries. The random coefficient model allows to track waves of reliance on analysts’
forecasts and nonfundamental stock price components across time and clearly identifies the growth of the nonfundamental component
in the long 1991–2000 swing.
