Reconsidering the role of money for output, prices and interest rates

New Keynesian models of monetary policy downplay the role of monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. This paper evaluates the empirical validity of this prediction by studying the effects of shocks to monetary aggregates using a vector autoregression (VAR). Shocks to monetary aggregates are identified by the restrictions suggested by New Keynesian monetary models. Contrary to the theoretical predictions, shocks to broad monetary aggregates have substantial and persistent effects on output, prices and interest rates.     

International strategy and performance—Clustering strategic types of SMEs

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.     

Tariff‐tax Reforms in Large Economies

This paper studies tariff‐tax reforms in a two‐region global New Keynesian model composed of a developing and an advanced region. In our baseline calibration, a revenue‐neutral reform that lowers tariffs in developing countries can reduce domestic welfare. The reason is that the increase in developing countries welfare due to higher output is dominated by the welfare losses stemming from the deterioration of the terms of trade. On the other hand, the reform increases output and welfare in the advanced countries and in the world as a whole. The effects that we highlight have not been studied in previous contributions to the literature, which looks at tariff‐tax reforms using a small open economy framework. Nominal rigidities have important implications for adjustment dynamics in our model. In the case of a ‘point‐for‐point’ reform, for example, price stickiness implies that the international dynamics of output is reversed compared to a revenue‐neutral reform.     

Regulating Public Transit Networks: How do Urban‐Intercity Diversification and Speed‐up Measures Affect Firms’ Cost Performance?

Abstract Empirical studies on the cost structure of Public Transit Networks are mainly based on specialized firms providing urban or intercity services. In this study we estimate a translogarithmic variable cost function to assess the behaviour of returns to scale and the impact of network characteristics. The analysis is based on a sample of 45 Italian municipal companies observed from 1996 to 1998 and including both specialized and mixed transit operators. Results confirm previous evidence on the existence of natural monopoly in the industry and support a regulation introducing competitive tenders to access to the market. In addition, we provide insights about the advantages associated with urban‐intercity diversification and with the improvement of network commercial speed. Cost benefits can then be achieved by promoting mergers between neighbouring firms, so as to create new companies operating on integrated local networks and supplying in combination urban and intercity public transport. Implications of such a strategy for the design of tender mechanisms are also underlined, together with the need for a regulatory policy which takes more care of speed‐up measures.     

Joint-search theory: New opportunities and new frictions

The job-search problem of couples differs in significant ways from that of singles. We characterize the reservation wage strategies of a couple that perfectly pools income to understand the ramifications of joint search for individual labor market outcomes. Two cases are analyzed. First, when couples are risk averse and pool income, joint search yields new opportunities relative to single-agent search. Second, when spouses receive job offers from multiple locations and incur a cost when living apart, joint search features new frictions and can lead to worse outcomes than single-agent search.
