Productivity differences and inter-state migration in the U.S.: A multilateral gravity approach

Anindya S. Chakrabarti and Aparna Sengupta

Economic Modelling

In this paper, we study the quantitative role of productivity differences in explaining migration in presence of multiple destination choices. We construct a dynamic general equilibrium model with multi-region, multi-sector set-up where labor is a mobile input, which adjusts to regional and sectoral productivity shocks, resulting in migration across regions. The proposed model generates a migration network where the flow of migrants between any two regions follows a gravity equation. We calibrate the model to the U.S. data and we find that variation in industrial and regional total factor productivity shocks explains about 63% of the interstate migration in the U.S. Finally, we perform comparative statics to estimate the effects of long-run structural changes on migration. We find that capital intensity of the production process and the demand for services over manufactured goods negatively impact aggregate level of migration whereas asymmetries in trade patterns do not appear to have substantial effects.

Quantifying invariant features of within-group inequality in consumption across groups.

Anindya S. Chakrabarti, Arnab Chatterjee, Tushar Nandi, Asim Ghosh, and Anirban Chakraborti

Journal of Economics interaction and Coordination

We study unit-level expenditure on consumption across multiple countries and multiple years, in order to extract invariant features of consumption distribution. We show that the bulk of it is lognormally distributed, followed by a power law tail at the limit. The distributions coincide with each other under normalization by mean expenditure and log scaling even though the data is sampled across multiple dimension including, e.g. time, social structure and locations. This phenomenon indicates that the dispersions in consumption expenditure across various social and economic groups are significantly similar subject to suitable scaling and normalization. Further, the results provide a measurement of the core distributional features. Other descriptive factors including those of sociological, demographic and political nature, add further layers of variation on the this core distribution. We present a stochastic multiplicative model to quantitatively characterize the invariance and the distributional features.

Investigating a comparative evaluation approach in explaining loyalty

Anand Kumar Jaiswal and Jos G.A.M. Lemmink

Marketing Intelligence and Planning

Purpose

The purpose of this paper is to examine the superiority of comparative evaluation or relative attitudinal measurement approach in which the respondent evaluates one object with direct comparison with other objects. The study uses comparative and non-comparative approaches to examine the effects of service quality, value, and customer satisfaction on attitudinal loyalty in a service setting.

Design/methodology/approach

The study uses the data collected from the survey of 300 customers of two large Indian banks.

Findings

The results provide partial support to the superiority of the comparative evaluation over non-comparative evaluation. Additionally, results indicate that service quality positively affects customer value, and both service quality and customer value have a direct positive effect on customer satisfaction. Customer satisfaction drives attitudinal loyalty which in turn leads to customers’ willingness to pay more.

Research limitations/implications

In the study, two banks were used for comparative evaluation. Since consumers’ consideration set can consist of more than two alternatives, future studies can include more than two objects.

Practical implications

Non-comparative measurements do not always adequately explain customer loyalty and superior performance of firms. This could potentially lead to misinterpretations of effects of service quality improvement programs and thus sub-optimal management decisions. Managers should use comparative evaluation approach for measuring marketing variables wherever possible.

Originality/value

Although the use of comparative evaluation is suggested in the literature (Dick and Basu, 1994), extant research has not systematically examined its superiority over non-comparative evaluation. This study empirically tests the comparative evaluation approach against the non-comparative approach by examining a comprehensive model involving the interrelationships among service quality, value, customer satisfaction, and their impact on attitudinal loyalty and willingness to pay more.

Emergence of anti-coordination through reinforcement learning in generalized minority games

Anindya S. Chakrabarti and Diptesh Ghosh

Journal of Economic Interaction and Coordination

In this paper we propose adaptive strategies to solve coordination failures in a prototype generalized minority game model with a multi-agent, multi-choice environment. We illustrate the model with an application to large scale distributed processing systems with a large number of agents and servers. In our set up, agents are assigned responsibility to complete tasks that require unit time. They request servers to process these tasks. Servers can process only one task at a time. Agents have to choose servers independently and simultaneously, and have access to the outcomes of their own past requests only. Coordination failure occurs if more than one agent simultaneously requests the same server to process tasks at the same time, while other servers remain idle. Since agents are independent, this leads to multiple coordination failures. In this paper, we propose strategies based on reinforcement learning that minimize such coordination failures. We also prove a null result that a large category of probabilistic strategies which attempts to combine information about other agents’ strategies, asymptotically converge to uniformly random choices over the servers.

Investigating a An evolutionary analysis of growth and fluctuations with negative externalities

Anindya S. Chakrabarti and Ratul Lakhar

Dynamic Games and Applications

We present an evolutionary game theoretic model of growth and fluctuations with negative externalities. Agents in a population choose the level of input. Total output is a function of aggregate input and a productivity parameter. The model, which is equivalent to a tragedy of the commons, constitutes an aggregative potential game with negative externalities. Aggregate input at the Nash equilibrium is inefficiently high causing aggregate payoff to be suboptimally low. Simulations with the logit dynamic reveal that while the aggregate input increases monotonically from an initial low level, aggregate payoff may decline from the corresponding high level. Hence, a positive technology shock causes a rapid initial increase in aggregate payoff, which is unsustainable as agents increase aggregate input to the inefficient equilibrium level. Aggregate payoff, therefore, declines subsequently. A sequence of exogenous shocks, therefore, generates a sustained pattern of growth and fluctuations in aggregate payoff.

Emergence of distributed coordination in Kolkata Paise Restaurant problem with finite information

Diptesh Ghosh and Anindya S. Chakrabarti

Physica: Statistical Mechanics and its Applications

In this paper, we study a large-scale distributed coordination problem and propose efficient adaptive strategies to solve the problem. The basic problem is to allocate finite number of resources to individual agents in the absence of a central planner such that there is as little congestion as possible and the fraction of unutilized resources is reduced as far as possible. In the absence of a central planner and global information, agents can employ adaptive strategies that uses only a finite knowledge about the competitors. In this paper, we show that a combination of finite information sets and reinforcement learning can increase the utilization fraction of resources substantially.

High-performance work systems and creativity implementation: the role of psychological capital and psychological safety

Promila Agarwal and Elaine Farndale

Human Resource Management

Unimplemented creative ideas are potentially wasted opportunities for organisations. Although it is largely understood how to encourage creativity among employees, how to ensure this creativity is implemented remains underexplored. The objective of the current study is to identify the underlying mechanisms that explain the relationship between high-performance work systems and creativity implementation. Drawing from the job demands–resources model, we explore a model of psychological capital and psychological safety as mediators in the relationship between high-performance work systems and creativity implementation. Based on 505 employee survey responses, the findings show support for the mediating relationships, highlighting the importance of psychological mechanisms. The study has important implications for HRM, uncovering how people management practices can encourage creativity implementation in the workplace.

The relationships between leadership, work engagement and employee innovative performance: empirical evidence from the Indian R&D context

Vishal Gupta, Shailendra Singh, and Abhijit Bhattacharya

International Journal of Innovation Management

Integrating the behavioural theory of leadership with job demands–resources theory of engagement, the present study examines the process through which leadership impact R&D professionals’ innovative work behaviours and innovative performance (measured through peer-reviewed journal papers, patents, PhDs guided and keynote addresses delivered). Data from 467 scientists working in India’s largest civilian R&D organisation were collected and analysed using structural equation modelling. The study found that work engagement was positively related to innovative work behaviours as well as innovative performance. Leader behaviours had significant indirect effects on innovative work behaviours as well as innovative performance via work engagement. While the total effect of leadership on innovative work behaviours, the total effect was non-significant for innovative performance. Implications for theory and practice are discussed.

Effects of non-conformity on perceived status and competence: Examining the moderating role of physical attractiveness

Biswajida Parida and Vishal Gupta

Psychological Studies

The present study attempts to examine how people perceive non-conforming behaviour and what do they infer about subjects who demonstrate non-conformity. Interviews were conducted to determine the operational definition and perception about non-conformity. Analysis of the interviews revealed that non-conformity is attributed to not abiding by the rules that have been defined or laid out by an authority in a particular context. Scenario-based experiments were conducted, and the obtained data were analysed to reach a conclusion regarding observers’ perception about non-conforming individuals in a collectivist culture. The results showed that non-conforming behaviour leads to a negative inference about status and competence. Also, we found that the attractiveness of non-conforming individuals does not lessen the negative inferences derived by the observers in a collectivist culture. The findings can be extended to devise several communication and signalling strategies to influence the mass behaviour in a collectivist culture, like India. The study provides us insights about achieving social objectives as well as driving behavioural change in a collectivist context.
