Subordinate‐Superior Upward Communication: Power,Politics, and Political Skill

A multiphase study involving 1,285 respondents was conducted to answer an important yet overlooked question: for a job requiring frequent informal communication with superiors, should an organization focus more on selecting employees with higher trait‐like willingness to communicate or on providing an environment where the flow of communication is easy and aided? We found support for the latter. Further, we observed that subordinates alter their communication behaviors based on the perception of superior's power, politics in the organization, and their own political skills. The study contributes to a better understanding of how situational variables affect subordinate‐superior upward communication. Implications of the study are also discussed. © 2016 Wiley Periodicals, Inc.     

How effective is monetary transmission in low-income countries? A survey of the empirical evidence

This paper surveys the evidence on the effectiveness of monetary transmission in low-income countries. It is hard to come away from this review with much confidence in the strength of monetary transmission in such countries. We distinguish between the “facts on the ground” and “methodological deficiencies” interpretations of the absence of evidence for strong monetary transmission. We suspect that “facts on the ground” are an important part of the story. If this conjecture is correct, the stabilization challenge in developing countries is acute indeed, and identifying the means of enhancing the effectiveness of monetary policy in such countries is an important challenge.

Demographic volatility and economic growth: convention and beyond

Following the success of endogenous growth theory, recent empirical examinations of the demography–economic growth construct established that components of demographic change can provide meaningful and clear insights into the direction and impact of demographic variation in economic growth. While theoretical justification and empirical support to the claim cannot be denied, confusions seem to have arisen whether an empirical growth construct will only be limited to demographic dynamics or the model can entertain other non-demographic variables. In a leading research, Kelley and Schmidt (1995, 2001) provided seemingly ambiguous evidence that addition of non-demographic variables can add explanatory power to the growth regression. While subsequent empirical growth models have largely followed the convention as in KS, some important considerations like the stochastic effects of demographic system on economic growth seem to be missing. This paper attempts to address the concerns by suggesting a long-memory demographic system and embedding stochastic demographic characteristics in a standard Solow–Swan model, which also forms the basis of convergence pattern. We empirically show that significant stochastic shocks exist in the demographic components which could have contributed to the growth volatility across nations. We suggest that empirical growth models should account for stochastic demographic characteristics to enable economic policy makers with correct information about the current and future state of evolution of the demography–economic system.     

Characterization of the Walrasian equilibria of the assignment model

We study the assignment model where a collection of indivisible goods are sold to a set of buyers who want to buy at most one good. We characterize the extreme and interior points of the set of Walrasian equilibrium price vectors for this model. Our characterizations are in terms of demand sets of buyers. Using these characterizations, we also give a unique characterization of the minimum and the maximum Walrasian equilibrium price vectors. Also, necessary and sufficient conditions are given under which the interior of the set of Walrasian equilibrium price vectors is non-empty. Several of the results are derived by interpreting Walrasian equilibrium price vectors as potential functions of an appropriate directed graph.     

Jumps in cross‐sectional rank and expected returns: a mixture model

We propose a new nonlinear time series model of expected returns based on the dynamics of the cross‐sectional rank of realized returns. We model the joint dynamics of a sharp jump in the cross‐sectional rank and the asset return by analyzing (1) the marginal probability distribution of a jump in the cross‐sectional rank within the context of a duration model, and (2) the probability distribution of the asset return conditional on a jump, for which we specify different dynamics depending upon whether or not a jump has taken place. As a result, the expected returns are generated by a mixture of normal distributions weighted by the probability of jumping. The model is estimated for the weekly returns of the constituents of the SP500 index from 1990 to 2000, and its performance is assessed in an out‐of‐sample exercise from 2001 to 2005. Based on the one‐step‐ahead forecast of the mixture model we propose a trading rule, which is evaluated according to several forecast evaluation criteria and compared to 18 alternative trading rules. We find that the proposed trading strategy is the dominant rule by providing superior risk‐adjusted mean trading returns and accurate value‐at‐risk forecasts.

Inter-Group Inequalities in Child Undernutrition in India: Group Analogue of the Gini Coefficient and Atkinson's Index

Studies of undernutrition in India (and elsewhere) have focused exclusively on interpersonal inequalities, and estimates of the magnitude of inter-group inequalities are unavailable. A focus on “horizontal”, or group-based, inequalities offers vital policy insights that would be lost in an approach based purely on interpersonal inequalities. We therefore apply the group analogues of Atkinson's index and the Gini coefficient to shed light on the disproportionate burden of undernourishment borne by rural and historically vulnerable caste groups. Furthermore, the prominent determinants of inter-group disparities are identified through Blinder–Oaxaca decomposition analysis. The paper calls for explicit targeting of backward castes across the country and improved inter-sectoral collaboration to ensure equitable access to education, health care and water and sanitation, particularly across underdeveloped regions.     

For Indian online shoppers,have saying and doing parted ways?

Grounded in the theory of planned behavior (TPB) and based on both perceptual as well as behavioral data, the study explores e‐service quality (e‐SQ) dimensions’ influence on merchandise value perception (MVP) and how these value perceptions, in turn, impact shopper loyalty intention, finally leading to word‐of‐mouth (WOM) and store patronization behavior. The model was tested for measurement and structural validity, mediation by MVP, and moderation by gender. Findings suggest that: (1) e‐SQ dimensions of efficiency and fulfillment have direct effect on MVP; (2) MVP is a key mediating variable facilitating “indirect‐only” mediation between e‐SQ dimensions and online shoppers’ loyalty intentions; (3) mediation by MVP is not moderated by gender; (4) strong association between shoppers’ loyalty intention and intention to spread positive WOM; and (5) “saying” and “doing” are incompatible because online shoppers’ loyalty intentions or WOM do not translate into store patronization behavior.
