Determinants of violent and property crimes in England and Wales: a panel data analysis 总被引:1,自引:0,他引:1
We examine various determinants of property and violent crimes by using police force area level (PFA) data on England and Wales over the period of 1992–2008. Our list of potential determinants includes two law enforcement variables namely crime-specific detection rate and prison population, and various socio-economic variables such as unemployment rate, real earnings, proportion of young people and the Gini Coefficient. By adopting a fixed effect dynamic GMM estimation methodology we attempt to address the potential bias that arises from the presence of time-invariant unobserved characteristics of a PFA and the endogeneity of several regressors. There is a significant positive effect of own-lagged crime rate. The own-lagged effect is stronger for property crime, on an average, than violent crime. We find that, on an average, higher detection rate and prison population leads to lower property and violent crimes. This is robust to various specifications. However, socio-economic variables with the exception of real earnings play a limited role in explaining different crime types. 相似文献

Abstract. This paper provides a review of the theoretical literature on rural–urban migration in contemporary LDCs. The paper begins with a brief discussion of the Lewis model before going on to discuss the Todaro and the Harris–Todaro models and the large literature which these models have spawned. The question of job search in the context of migration and the role of family members in migration decisions are considered next. The paper then takes a closer look at the Informal sector and also sets out alternative migration functions to the ones usually employed in the literature. The paper concludes with a brief note on some of the important implications arising from our study. 相似文献

Abstract. The paper analyses the competitive process and performance behaviour of Japanese manufacturing between 1985 and 1997. Technological changes, international competition and reducing barriers in domestic and international markets are playing a significant role to speed up the performance behaviour in Japanese manufacturing. Scale economies, product differentiation and openness of the economy are used in explaining profit behaviour of manufacturing firms. Findings are compared with existing studies from Japan as well as from other developed countries such as Australia and the USA. 相似文献

Supply chains are large, complex, and often unpredictable. Purchasing and supply managers and supply chain risk managers need methods and tools to enable them to quickly understand how unexpected disruptions in the supply chain start and grow and to what extent will they negatively impact the flow of goods and services. This paper introduces a methodological approach that can be used by both researchers and managers to quickly visualize a supply chain, map out the propagation path of disruptive events from the supply side to the end customer and understand potential weaknesses in the supply chain design; taking into account the structure, connectivity, and dependence within the supply chain. The approach incorporates a Petri net and Triangularization Clustering Algorithm to offer insights into a supply chain network's vulnerabilities and can be used to efficiently assess supply chain disruption mitigation strategies, especially in complex and difficulty to analyze supply chain systems. 相似文献

The paper attempts to examine whether there is price convergence across various regions in India. Using panel unit root tests
that are robust to cross-sectional dependence, it is found that relative price levels among various regions in India are mean-reverting.
Further, we decompose each series into a set of common factors and idiosyncratic components. The decomposition enables us
to test stationarity and estimate half-lives of the common factors and the idiosyncratic components separately. Both these
components are found to be stationary. Idiosyncratic price shocks, however, are found to be more persistent as compared to
the common factor. Results also indicate that transportation cost proxied by distance can explain a part of the variation
in prices between two locations in India.

We study the properties of two-period monetary cycles in simple pure exchange overlapping generations economies in which the households live for three periods. We demonstrate that these economies can support cycles under a much broader—and, arguably, more plausible—range of assumptions than the analogous two-period economies. We show that economies that fail the well-known Grandmont (Econometrica 53 (1985) 995) condition can have cycles, and that economies that satisfy the condition can fail to have cycles. In addition, we show that economies can have monetary cycles when they do not have conventional monetary steady states, and when aggregate demand for assets is not decreasing in the real return rate at a gross real rate of unity. 相似文献

Published statistics on short sales of stock are used by investors as a technical indicator of market timing. Research on this topic is mixed. Findings in this article rely on causality tests that use white noise residuals generated from time-series analysis of short sales. Results indicate that specialists' short sales lead short sales of other investors, but these other investors are unable to take advantage of the information because a time lag exists in the published data. 相似文献

It is widely believed that successful bargaining helps consumers increase their surplus. We present evidence from a field experiment showing that bargaining over price reduces buyer surplus in a marketplace where sellers cheat on the weight whose value may more than offset the price discount. Our results show that bargaining entails hidden costs since sellers cheat significantly more when buyers bargain than not and they cheat significantly more when bargaining succeeds than fails. Overall bargaining reduces buyer surplus than not bargaining. Our result is relevant for credence goods markets where bargaining over prices may induce sellers to “undertreat” more. 相似文献
