We exploit a comprehensive new panel dataset on retailbank branch locations in 233 neighborhoods (local markets) in the metropolitan area of Antwerp to describe (i) how between 1991 and 2006 the patterns of bank presence, entry, exit and choice deeply evolve and (ii) whether and how changes in these “on the ground” patterns systematically diverge across Antwerp’s different, highly segregated neighborhoods. We show that over the 15-year period under study entry and exit dynamics substantially intensify, the level change in branch desert grows significantly, and bank choice markedly declines; and that between 1996 and 2001, these changes are robustly associated with the neighborhood average income. In doing so, we advance a new technique for generating spatial measures that both minimize the discretization bias and can be reliably linked to neighborhoods. We demonstrate that the resulting measures are indeed more precise than traditional count measures.  相似文献

This paper provides an estimate of the contribution of the ecosystem to the provisioning services generated by agriculture. This is achieved by valuing the changes in productivity generated by a marginal alteration in ecosystem inputs. As an example, we consider the variation in rainfall and temperature projected by the recent UK Climate Impacts Programme. The analysis implements a spatially explicit, econometric model of agricultural land use based on the methodology recently developed by Fezzi and Bateman (Am J Agric Econ 93:1168–1188, 2011). Land use area and livestock stocking rates are then employed to calculate farm gross margin estimates of the value of changes in provisioning ecosystem services. Findings suggest that the variation in ecosystem inputs induced by climate change will have substantial influence on agricultural productivity. Interestingly, within the UK context climate change generates mainly positive effects, although losses are forecasted for those southern areas most vulnerable to heat-stress and drought.  相似文献

Empirical estimates of monetary policy reaction functions feature a very high estimated degree of monetary policy inertia. This evidence is very hard of reconcile with the alternative evidence of low predictability of monetary policy rates. In this paper we examine the potential relevance of the problem of weak instruments to correctly identify the degree of monetary policy inertia in forward-looking monetary policy reaction function of the type originally proposed by Taylor [1993. Discretion versus policy rules in practice. Canergie-Rochester Conference Series on Public Policy, 39, 195–214]. After appropriately diagnosing and taking care of the weak instruments problem, we find an estimated degree of policy inertia which is significantly lower than the common value in the empirical literature on monetary policy rules.  相似文献

We describe a model of trade with skills-based product differentiation and non-proportional trade costs that predicts a positive correlation between firms' export intensity, the price of their exports and the wages they pay to their workers. In equilibrium, firms that employ workers with comparatively scarcer skills export a larger proportion of their output, pay higher wages and charge higher prices. In line with empirical evidence, the model predicts that trade liberalization can cause the distribution of earnings to become more polarized, with patterns that reflect the heterogeneous effects of trade liberalization on firms' export performance.  相似文献

We study the impact of ultra-broadband (UBB) internet connections on firm entry and exit dynamics. These connections are based on optical fiber cables that link telecommunication operators to final users, allowing a significantly higher performance compared with traditional copper-line networks. We leverage on a unique comprehensive dataset collecting municipality-level information on broadband diffusion and firm turnover in Italy for the period of 2012–2019. Our empirical strategy exploits the staggered roll-out of UBB, starting from 2015. Our identification strategy is based on an instrumental variable approach that exploits plausibly exogenous variation in the physical and geographical peculiarities of the telecommunication infrastructure. Results suggest that UBB increases firm exit, particularly for small firms. On the contrary, firm entry rises only in digital intensive sectors and in the most developed geographical areas. Our findings have important implications for the ongoing debate around the massive investments in high-speed digital infrastructures, as they argue against the conventional idea that business activities equally benefit from last-generation broadband technologies.  相似文献
