Using U.S. data from 1950 to 2010, we analyze to what extent inflation raises the incidence of property crime. To match our theoretical predictions, we consider different types of property crime (larceny, burglary, motor vehicle theft, and robbery) and broad and narrow definitions of inflation separately. We control for the state of the business cycle and demographic changes over time explicitly. Unobserved or difficult‐to‐measure determinants of property crime are captured through a stochastic‐trend specification within a state‐space framework. We find a robust statistical link between inflation and each of the four property crime rates. Our findings are robust to alternative definitions of inflation and the inclusion or exclusion of different control variables. In terms of policy, our findings suggest that monetary policy that creates inflation has costly spillover effects. (JEL J10, J11)  相似文献

We point to deficits in current global institutional arrangements in support of agricultural development and food and nutrition security. A framework for global institutional arrangements proposed here is the set of essential international public goods for a well‐functioning world food system. These public goods include international natural resource management; trade and transboundary competition policy; research and innovation; handling large scale food emergencies; and transboundary food safety. Based on the framework, and institutional economics considerations, causes of current malfunctioning of global food governance are analyzed. It is proposed to redesign global food governance by establishing an international platform with policy clusters mapped along the set of global public goods. To support the platform with needed research‐based evidence an International Panel on Food, Nutrition and Agriculture (IPFNA) is suggested, partly following the design of the Intergovernmental Panel on Climate Change (IPCC). Existing organizations and mechanisms would form building blocks of the strengthened and redesigned governance system. A gradual approach toward redesign is proposed. Some redesign in the suggested direction was triggered by the food crisis of 2008, as demonstrated by the reform of the Committee on Food Security (CFS) with its high level panel of experts, but more is needed.  相似文献

This article studies repeated entry and bidding decisions in construction procurement auctions. I find evidence in the data that suggests the presence of significant cost savings from entering contracts of the same type. I estimate a dynamic auction model to measure the gains to experience for bidders. I allow for endogenous entry, synergies in entry, and unobserved auction heterogeneity. I find that a bidder can halve entry costs by focusing on specific contract types. An auctioneer can increase competition by awarding contracts of the same type in sequence. As a result, procurement costs for each contract can be lowered by 7%, a saving of $110,000.  相似文献

Abstract. From a model by Hopenhayn, three hypotheses can be derived: (H1) Firms that exit in year t were less productive in t− 1 than firms that continue to produce in t. (H2) Firms that enter in year t are less productive than incumbent firms in year t. (H3) Surviving firms from an entry cohort were more productive than non-surviving firms from this cohort in the start year. This paper uses unique newly available panel datasets for all manufacturing plants from Germany (1995–2002) to test these hypotheses. All three hypotheses are supported empirically for West and East Germany.  相似文献

We use a novel classification scheme to identify three stages of production in the manufacturing sector: parts, components and final goods. In particular, we offer evidence on the revealed comparative advantage of the EU-27 countries concerning the three vertically separated stages of production. Moreover, we investigate whether, and if so how, imports of parts, and components can work as a predictor for the exports of final goods. We find that countries specialize at different stages of production, and that components are Granger causal for the export of final goods in many countries with a lag of 3 months.  相似文献

This article examines evidence for the private rationality of decisions to choose bottled water using a large, nationally representative sample. Consumers are more likely to believe that bottled water is safer or tastes better if they have had adverse experiences with tap water or live in states with more prevalent violations of EPA water quality standards. Perceptions of superior safety, taste, and convenience of bottled water boost consumption of bottled water. Blacks and Hispanics are more likely to drink bottled water due to their relatively greater exposure to unsafe water and greater risk beliefs. The coherent network of experiences, beliefs, and actions is consistent with rational consumer choice. (JEL D12, D80, Q50)  相似文献

Export sophistication and economic growth: Evidence from China   总被引:3,自引:0,他引:3  
We consider the effect of export sophistication on economic performance by appealing to regional variation within one single country (China) over the 1997-2009 period. We find evidence in support of Hausmann, Hwang and Rodrik (2007), in that regions specializing in more sophisticated goods subsequently grow faster. We find substantial variation in export sophistication at the province and prefecture level, controlling for the level of development, and that this sophistication in turn drives growth. Our results suggest that these gains are limited to the ordinary export activities undertaken by domestic firms: no direct gains result from either processing trade activities or foreign firms, even though these are the main contributors to the global upgrading of China's exports. As such, the extent of assembly trade and foreign entities should be distinguished in order to measure the true movement in a country's technology and the contribution of exports to economic growth.  相似文献

Surveys of consumption expenditure vary widely across many dimensions, including the level of reporting, the length of the reference period, and the degree of commodity detail. These variations occur both across countries and also over time within countries, with little current understanding of the implications of such changes for spatially and temporally consistent measurement of household consumption and poverty. A field experiment in Tanzania tests eight alternative methods of measuring household consumption, finding significant differences between consumption reported by the benchmark personal diary and other diary and recall formats. Under-reporting is particularly apparent for illiterate households and for urban respondents completing household diaries; recall modules measure lower consumption than a personal diary, with larger gaps among poorer households and for households with more adult members. Variations in reporting accuracy by household characteristics are also discussed and differences in measured poverty as a result of survey design are explored.  相似文献
