An empirical analysis of self-employment in the U.K.

The paper formulates a self-employment/paid-employment choice problem that draws upon Knight's notion that the individual responds to the risk-adjusted relative earnings opportunities in each sector. Based on a development of such choice-theoretic considerations, an econometric model is developed with the purpose of empirically examining the determinants of self-employment. The model features simultaneous determination of employment status and earnings, which allows for self-selectivity. The model is estimated using a sample of 4762 individuals from the General Household Survey for 1978. The estimation of the earnings equation enables a calculation of the self-employment/paid-employment earnings differential and the estimated probit equation for self-employment/paid-employment status facilitates the prediction of the probability of self-employment. The paper finds that there is positive selection bias in the observed earnings of employees, that the probability of self-employment depends positively on the earnings difference between the two sectors and that education and age are significant determinants of self-employment.     

Navigating the Impact of Globalization on Bank Efficiency in China

The paper provides for the first time empirical evidence on the impact of economic globalization on bank efficiency in a developing economy. Using the data envelopment analysis method, we compute the efficiency of the Chinese banking sector during 2000–2007. The empirical findings suggest that the inefficiency of the Chinese banking sector stems largely from scale rather than pure technical inefficiencies. Examining different components of economic globalization, we find that greater economic integration through higher trade flows, cultural proximity and political globalization have significant and positive influence on bank efficiency levels. The empirical findings suggest that liberalization (restrictions) of the capital account exerts a negative (positive) influence on bank efficiency levels in China.     

Do men and women really shop differently? An exploration of gender differences in mall shopping in India

‘Men Buy and Women Shop’ proclaims a new Wharton Research on shopping habits of the American consumer (2007). There is found to be considerable difference in the way men and women shop in the West. Is this true across cultures? Indian retailing is generating considerable interest within the country and abroad. India has been rated as the fifth most attractive emerging retail market and was ranked first in a Global Retail Development Index of 30 developing countries drawn up by A T Kearney. Organized retail, best represented by the mushrooming malls, has come to play a defining role in building and supporting this veritable base of retail consumers. Therefore, it is of utmost interest to retailers and academia alike to understand the consumer dynamics behind the newly evolving consumption culture. This study explores mall‐shopping habits in India and attempts to identify and contrast possible differences between genders using a sample of 2721 mall consumers across seven cities. While the findings suggest that in India there are significant differences in shopping behaviour that can be ascribed to gender, there are fundamental questions about stereotyping of shopping as a feminine activity. To do this, discriminant analysis has been used to study whether shopping orientation and mall‐shopping attitudes can discriminate between male and female shoppers.     

Demand-side factors in optimal land conservation choice

The dominant paradigm of conservation-reserve planning in economics is to optimize the provision of physical conservation benefits given a budget constraint, implicitly assuming the value of biodiversity and ecosystem function is not affected by human proximity to that natural capital. There is evidence, however, that human willingness to pay (WTP) for conservation declines with distance—a phenomenon we call “spatial value decay”. This paper begins a new strand of the conservation planning literature that takes demand-side factors – location of people in the landscape, the degree to which WTP for conservation depends on proximity – into account. We use theoretical models of linear abstract landscapes to explore the impact of demand-side factors on two facets of conservation choices: siting of a single reserve when conservation potential is greatest near a critical site, and siting of multiple reserves when fragmentation reduces physical conservation services produced. Our results show how planners should sometimes employ increased fragmentation to capture value when people's preferences are not very highly localized, and how optimal policy balances proximity to the ecologically critical site with proximity to people. In some scenarios, the payoff to using a reserve design approach that considers demand-side factors is large, but we find that spatial value decay reduces the benefits that can be gained from any conservation-planning approach.     

A comment on Mendeş and Yiğit (2013), ‘Type I error and test power of different tests for testing interaction effects in factorial experiments’, Statistica Neerlandica, 67:1–26

In their advocacy of the rank‐transformation (RT) technique for analysis of data from factorial designs, Mende? and Yi?it (Statistica Neerlandica, 67, 2013, 1–26) missed important analytical studies identifying the statistical shortcomings of the RT technique, the recommendation that the RT technique not be used, and important advances that have been made for properly analyzing data in a non‐parametric setting. Applied data analysts are at risk of being misled by Mende? and Yi?it, when statistically sound techniques are available for the proper non‐parametric analysis of data from factorial designs. The appropriate methods express hypotheses in terms of normalized distribution functions, and the test statistics account for variance heterogeneity.     

Fiscal decentralization and macroeconomic management

The purpose of this paper is to address a central question in fiscal federalism - whether or not fiscal decentralization implies serious risks for fiscal discipline and macroeconomic management for the nation as a whole. This paper addresses this important issue by drawing upon the existing evidence regarding macro management and fiscal institutions in federal and unitary countries. This is supplemented by cross country regression analysis plus the analysis of two case studies: the Brazilian federation and the unitary regime in China. The main conclusion of the paper is that decentralized fiscal systems offer a greater potential for improved macroeconomic governance than centralized fiscal regimes. This is because the challenges posed by fiscal decentralization are recognized and they shape the design of countervailing institutions in federal countries to overcome adverse incentives associated with incomplete contracts or the “common property” resource management problems or with rent seeking behaviors.

E-optimal minimally connected block designs under mixed effects model

Summary Considering a mixed effects model in a minimally connected block design set-up, we obtain designs which areE-optimal, uniformly in the ratio of the variance components, for inference on varietal contrasts which constitute the fixed effects in the model.
