The aim of this investigation is to analyze the evolution of the spatio-temporal distribution of foreign direct investment (FDI) across Mexican states. The literature that analizes foreign direct invesment in Mexico is numerous and diverse; however, it is argued that the analysis of the spatio-temporal distribution of FDI conditioned to spatial interaction effects in Mexico, is still absence. In this sense, by applying the spatial Markov chain approach as proposed by Rey (2001), we found a divergence process in the FDI inflows among mexican states that seems to get stronger over time. In particular, during the period from 2006 to 2013, the process of divergence towards higher-FDI-inflows quantiles occurs among states spatially associated with neighbors in lower-FDI-quantiles.  相似文献

This paper examines the association between monitoring and earnings management by property-casualty insurers. Prior literature has evaluated the impact of auditors and actuaries on insurer reserving. We extend this work by considering the nonrandom nature of monitor assignment. We model the insurer decisions regarding choice of auditor and actuary jointly using a Heckman selection model. Consistent with prior literature, we account for potential loss reserving incentives that may confound these decisions. We find that the use of internal actuaries is significantly related to higher reserve errors, but this is reduced, but not fully offset, when the internal actuary is an officer of the insurer. We find lower reserve error for auditors from a Big N firm. However, the use of an auditor and actuary from the same Big N firm is significantly related to higher reserve errors.  相似文献

During the last 25 years, co-operation within the Dutch container transport industry has served in various ways as Q means of reducing rkk. Co-operation has been aimed chiefly at reducing financial risks, pooling financial resources, and regulating com- petition. In most cases, a direct solution of the problem of match- ing supply and demand has not been an important motive for CO- operation. In the early days of containerisation, industry culture was facilitating co-operation in liner shipping more than in the stevedoring and road haulage industries.  相似文献

We compare different methodological approaches to predicting the welfare effects of trade policy experiments. We focus on studies that estimate the economic effects of the Transatlantic Trade and Investment Partnership (TTIP). Methodologically, the studies can be divided into those employing computable general equilibrium (CGE) models and structural gravity (SG) models. We compare and critically discuss differences in the estimated trade cost reductions and in the economic models employed, and how these can explain the relatively wide range of economic effects found in the different TTIP studies. We conclude that reasonable estimates of the welfare effects for the TTIP partners are between 0.5% and 2%.  相似文献

Using the identification strategy proposed by Graham and Hahn (2005), we estimate the magnitude of classmate effects on math scores using Brazilian data from 2005. In addition, we provide a detailed discussion about the identification of endogenous peer effects in the linear in means models. Our results show that both peer characteristics (exogenous peer effects) – like race, socioeconomic status and gender – and peer actions (endogenous peer effects) are important determinants of students’ outcomes in the fifth grade of elementary school. Our estimates of endogenous peer effects are about 0.008 of 1 SD of math test scores, which can be interpreted as evidence of a so-called ‘conformist’ individual behaviour, under which students face large costs to exert effort levels that are distant from what is believed to be the norm in the classroom. Those estimates of endogenous peer effects imply a social multiplier of about 1.67.  相似文献

A model is developed of the relation between adoption of an innovation by firms and firm size. Decision making is represented as a group assessment of the perceived ratio between expected returns after succesful introduction, and the risk that implementation will fail or will last too long to makc adoption worth while. In view of differences in thc assessment of uncertainty and corresponding demands on the perceived return-to-risk ratio, among influencers of decisions in the firm, decision making is taken as stochastic, with a probability of adoption related to (objective) net benefits, and probability of non-adoption related to risk. The model gives a new way of looking at the fact that small firms lag behind in the adoption of new technology. In contrast with previous models proposed by David and Davies the explanation has nothing to do with there being some critical size below which adoption is not profitable. The present model explains the adoption lag for smaller firms as the result of expected returns being proportional to size while risk of failed implementation is independent of size. The model is tested and estimated empirically on data for the adoption of computers in small scale retailing, in the Netherlands.  相似文献
