Firm location choice in cities: Evidence from China,India, and Brazil

This paper contributes to the industrial location literature by examining why industry locates or refrains from locating in large, medium and small cities of India, China and Brazil using firm-level data from the World Bank. Results from ordered logistic regressions indicate that capital cities are not attractive for firms to locate, when they are large. In India and China, labor intensive firms do not locate in large cities. Proximity to inputs has a positive impact on firm location in China. While availability of inputs has a positive impact on firm location in India, the availability of raw materials has a negative impact on firm location in Brazil. Firms established in post-reform period in India tend to locate in large cities; in China, these firms avoid medium and large cities. The implications for urban governance in these countries are discussed.     

Least squares model averaging by Mallows criterion

This paper is in response to a recent paper by Hansen (2007) who proposed an optimal model average estimator with weights selected by minimizing a Mallows criterion. The main contribution of Hansen’s paper is a demonstration that the Mallows criterion is asymptotically equivalent to the squared error, so the model average estimator that minimizes the Mallows criterion also minimizes the squared error in large samples. We are concerned with two assumptions that accompany Hansen’s approach. The first is the assumption that the approximating models are strictly nested in a way that depends on the ordering of regressors. Often there is no clear basis for the ordering and the approach does not permit non-nested models which are more realistic from a practical viewpoint. Second, for the optimality result to hold the model weights are required to lie within a special discrete set. In fact, Hansen noted both difficulties and called for extensions of the proof techniques. We provide an alternative proof which shows that the result on the optimality of the Mallows criterion in fact holds for continuous model weights and under a non-nested set-up that allows any linear combination of regressors in the approximating models that make up the model average estimator. These results provide a stronger theoretical basis for the use of the Mallows criterion in model averaging by strengthening existing findings.

Liquidity constraint,uncertainty and household consumption in China

This paper investigates the changing roles played by liquidity constraint and uncertainty in accounting for the dynamism of Chinese household consumption behaviour. Starting from the Euler equation-based model of Robert Hall, a framework encompassing an array of consumption models is developed and applied to Chinese data over the period 1961?1998. Empirical results reveal a regime shift in the early 1980s and imply that increases in the proportion of liquidity constrained consumers and increased uncertainty in the post-reform period are responsible for the extremely low consumption or high savings in China. Moreover, it is found that interactions between liquidity constraint and uncertainty reinforce each other's effects and lead to declines in both the level and growth of consumption.     

Interpersonal Relationship,Service Quality,Seller Expertise: How Important Are They to Adolescent Consumers?

Drawing upon social capital theory and psychosocial development theory, this paper argues that a true buyer–seller relationship is a key determinant of favorable consumer behaviors for adolescent consumers of hairstylist services. Other important determinants include quality of the service delivery process (i.e., service quality as measured by the five SERVQUAL factors) and quality of the core service (in this case, the hairstylist's expertise). A survey of 350 adolescent consumers confirms these predictions. It shows that a true interpersonal relationship negatively moderates the positive effects of service quality on consumer satisfaction with, and overall assessment of the hairstylist. This negative moderating effect is labeled resource substitution benefit and the argument made that this is the fourth social capital benefit. The theoretical and practical implications of these findings are discussed. © 2012 Wiley Periodicals, Inc.     

Assessing the role of components of life satisfaction

Factors affecting subjective well-being and their gross effect measurement have been widely studied. However, how people derive utility from these factors has not been fully explored. This article provides a way to decompose the gross effect of major determinants on life satisfaction into direct and indirect effects and make inference for the latter. Because the indirect effect is nonlinear in parameters associated with different models in an equation system, it creates a problem in estimating the standard error. Besides, the categorical nature in survey data further introduces bias to the covariance estimation even asymptotically. To address these issues without knowing the form of heteroskedasticity under the null hypothesis, we propose to extend the wild bootstrap procedure in this particular context. Its robustness against various data properties is validated via several simulation experiments. Using three recent waves of World Values Survey, we find that the relative importance of life control has significantly increased recently, and endowing citizens with the right to enjoy their freedoms and liberties is a more effective policy in raising life satisfaction than promoting national income.
