Analysis of marginally specified semi-nonparametric models for clustered binary data

Generalized linear mixed models are widely used for analyzing clustered data. If the primary interest is in regression parameters, one can proceed alternatively, through the marginal mean model approach. In the present study, a joint model consisting of a marginal mean model and a cluster-specific conditional mean model is considered. This model is useful when both time-independent and time-dependent covariates are available. Furthermore our model is semi-parametric, as we assume a flexible, smooth semi-nonparametric density of the cluster-specific effects. This semi-nonparametric density-based approach outperforms the approach based on normality assumption with respect to some important features of 'between-cluster variation'. We employ a full likelihood-based approach and apply the Monte Carlo EM algorithm to analyze the model. A simulation study is carried out to demonstrate the consistency of the approach. Finally, we apply this to a study of long-term illness data.     

Reassessing Conditional Cash Transfer Programs

During the past decade, the use of conditional cash transferprograms to increase investment in human capital has generatedconsiderable excitement in both research and policy forums.This article surveys the existing literature, which suggeststhat most conditional cash transfer programs are used for essentiallyone of two purposes: restoring efficiency when externalitiesexist or improving equity by targeting resources to poor households.The programs often meet their stated objectives, but in someinstances there is tension between the efficiency and equityobjectives. The overall impact of a program depends on the gainsand losses associated with each objective.      

China and India： A Tale of Two Economies

I. Two Populous GiantsIt has been conventional wisdom to make comparison between the two geographicallylarge and populous countries, which share a long common border, have entrepreneurialtrading heritage, enormous internal diversity, large agricultural sectors, ancient culturesand almost five thousand years of histories. Both were noted for their economic prowess inthe past, albeit their more recent history of the last two centuries has been replete withdistressful colonization of one and eco…     

Power Politics and International Labor Standards

This paper analyzes how a country's commitment to labor standards is affected by the international political power they possess. Powerful countries may be less committed to actual enforcement of certain labor standards since they are unlikely to face significant threats of international sanctions regardless of their actions. The paper introduces an index of international power for 116 countries that is used to examine how power affects the extent to which countries enforce standards relating to freedom of association and collective bargaining. The evidence suggests that, even after controlling for differences in wealth, productivity, and market freedom, powerful countries are significantly less committed to the protection of labor standards than less powerful countries.

Hub-and-Spokes Free Trade Agreements in the Presence of Technology Spillovers: An Application to the Western Hemisphere

Using a comparative-static general equilibrium model in the context of the Western Hemisphere, this paper compares the economic effects of a “hub-and-spokes” type of bilateral trade configuration (with Chile being the hub) with those of a more comprehensive regional FTA (namely, the FTAA). The model is augmented to account for the possibility of technology spillovers and its effective assimilation among participating economies. In particular, absorptive capacity, governance factor, proximity and socio-institutional congruence conjointly determine an economy’s capacity to capture the technology that is transmitted from the developed spoke United States to other regions.

Organizational and decision characteristics and personality as determinants of control actions: A laboratory experiment

This paper investigates how choice of control actions (or behaviours) is affected by the controller's personality and perceptions of organizational and decision characteristics. In a simulated work setting (n = 172) it was found that persons working in mechanistic organizations chose significantly different control tactics than those working in organic organizations. The present findings also suggest that controllers are more likely to choose extrinsically (rather than intrinsically) motivating controls when they are faced with important decision situations. The implications of the findings are discussed. Multivariate models of choice of control tactics in organizations are suggested as being more powerful.     

A Study on the Indian Information Sector: An Experiment with Input-Output Techniques

It is widely recognized that rapid changes in information technology (IT) are bringing about major structural changes in the economies of the world. Information flexibility, product quality and fast response are the key factors for global competition and IT plays a critical role in these areas. Policy-makers in industrialized and developing countries view IT as a critical infrastructure to enhance their access to global knowledge, markets and capital. These views--of IT as infrastructure and as core capability for development--resonate with India's aspirations to modernize its infrastructure, transform its industry and join the global economy. Realizing the huge potential of the Indian IT industry, we make an attempt in this paper to study the extent of informatization in the Indian economy during the period 1983-84 to 1989-90 and try to identify the information intensive sectors. This paper also studies the sources of growth of the information sectors of India during 1983-84 to 1989-90 with the help of a structural decomposition analysis (SDA).     

Health care regulation and the operating efficiency of hospitals: Evidence from Taiwan

Using data from the Annual Survey of Hospitals compiled by the Department of Health in Taiwan for years 1994 through 1997, we employed Data Envelopment Analysis (DEA) to evaluate the impact of a National Health Insurance (NHI) Program on the operating efficiency of district hospitals in Taiwan. We find that, on average, efficiency of district hospitals in Taiwan decreased following the implementation of the NHI Program. Our results are robust to the inclusion of control variables that have been shown to affect hospital operating performance in prior research, and alternative efficiency measurements.     

Pricing Interest Rate Derivatives: A General Approach

The relationship between affine stochastic processes and bondpricing equations in exponential term structure models has beenwell established. We connect this result to the pricing of interestrate derivatives. If the term structure model is exponentialaffine, then there is a linkage between the bond pricing solutionand the prices of many widely traded interest rate derivativesecurities. Our results apply to m-factor processes with n diffusionsand l jump processes. The pricing solutions require at mosta single numerical integral, making the model easy to implement.We discuss many options that yield solutions using the methodsof the article.     

E-tailer personality and behavioral intentions: the application of self-congruity theory

The present study is an effort to develop an e-tailer personality scale. Subsequently, we check the impacts of e-tailer personality on self-congruity and behavioral intentions such as intention to re-shop and intention to recommend. We have followed a traditional scale development method – item generation, purification, and dimension assessment. A structure questionnaire has been used to collect primary data online. A structure equation model was used to analyze the data. This study has developed a e-tailer personality scale of five dimensions: sophistication, competence, excitement, sincerity, and convenience. The results of a structural equation model largely support the propositions that e-tailer personality is positively related to self-congruity. The results also show that e-tailer personality, behavioral intentions and self-congruity are positively related. A comparison of the developed scale with the existing brand personality scales, results in a unique dimension of e-tailer personality scale. Arguably, this study may be seen as a first study in an emerging economy and online retailing domain. The results have both academic and managerial implications.
