Household Finances and Social Interaction: Bayesian Analysis of Household Panel Data

We investigate the relationship between social interaction and household finances using the British Household Panel Survey. We explore the relationship between a wide range of aspects of household finances and social interaction, rather than focusing on one particular facet of household finances, such as the holding of stocks and shares. We develop a Bayesian statistical framework to simultaneously explore both sides of the household balance sheet—liabilities and assets. Additionally, we allow the influence of social interaction on household finances to be time dependent, enabling us to model the effects of social interaction from a dynamic perspective. We also develop a two‐part model to jointly investigate the influence of social interaction on the amount of different types of debt and financial assets held conditional on holding the different types of debt and assets. Our analysis suggests that social interaction is associated with households holding larger amounts of debt and assets.     

Exchange rate and foreign GDP elasticities of Swiss exports across sectors and destination countries

This article uses a detailed breakdown of Swiss trade flows to identify how the impact of the two main determinants of Switzerland’s exports – foreign demand and the real exchange rate – varies across sectors and export destinations. Our main findings are that (i) both foreign demand and exchange rate elasticities vary substantially across both export sectors and export destinations. (ii) Foreign demand trends are more important for structural considerations than the exchange rate. This is due to the fact that exports of the two largest export sectors are relatively sensitive to long-run foreign demand developments while they are relatively insensitive to changes in the exchange rate. (iii) The sectoral structure of Switzerland’s exports has shifted towards goods that have a lower short-run demand elasticity and a higher long-run demand elasticity. Goods exports are thus less influenced by business cycle fluctuations while they benefit more from long-term growth trends. (iv) The export share of sectors with a relatively low exchange rate elasticity has increased. However, this result is mainly driven by the strong rise in exports of chemicals and pharmaceuticals as well as precision instruments and watches, which are also the two important sectors responsible for the Swiss trade surplus.     

Rural-Urban Differences in the Unemployment-Crime Relationship: The Case of Pennsylvania

This study analyzes the unemployment-crime (U-C) relationship in urban and rural Pennsylvania counties using a balanced panel data set over the period from 1990 to 2009. A two-way fixed effects model is estimated to account for unobserved county-specific and time-specific heterogeneity. The criminal opportunity and criminal motivation effects of unemployment on crime advanced by Cantor and Land are tested. The results suggest that there are rural-urban differences in the impacts of the covariates. Specifically, both statistically significant criminal opportunity and criminal motivation effects are present in urban counties. In contrast, rural counties fail to conform to U-C predictions. Oaxaca decomposition reveals that the unexplained portion of the rural-urban difference in the crime rate is 12%. The results provide support for addressing labor market conditions to complement traditional crime-fighting measures in urban settings.     

An examination of firms' employment costs

The existence of quasi-fixed costs of work may affect firms' desired employee hours and number of workers, which has important implications for the estimation of labour supply parameters. Firm-level data from the 1982 Employment Opportunity Pilot Project is used to estimate the importance to firms of employee quasi-fixed costs related to searching, hiring, training, and firing. Specifically, this paper examines how these costs affect number of workers and hours per worker, turnover, and vacancies, to the extent that the costs are determined by the firm's presumably exogenous industrial classification. An attempt is made to control for biases due to employee heterogeneity as well. Results show that higher costs are associated with lower turnover, fewer vacancies, and longer hours as predicted by a model of labour demand.     

Favor trading in public good provision

Favor trading is common. We do something nice for someone and they do something nice in return. Several motives might underlie such behavior, including altruism, strategic motives, and direct or indirect positive reciprocity. It is not yet well-understood how these fit together to affect behavior, how they interact in various institutional structures, and how they play out over time. We use a laboratory experiment to study the elements and dynamics of favor trading in a particular setting: the private provision of a public good. In our experiment, giving subjects the ability to practice targeted reciprocity by making a simple, low-cost change in information provision increases contributions to the public good by 14 %. Subjects reward group members who have previously been generous to them and withhold rewards from ungenerous group members. Strategic concerns cannot explain all of this behavior, and it must be at least partly due to direct reciprocity. When someone cannot directly benefit from favor trading, he gives much less to the public good. People thus excluded from the “circle of reciprocity” provide a clean and strict test of indirect reciprocity. Contrary to previous studies in the literature, we do not observe indirect reciprocity.     

Consumer response to norm-breaking pricing events in e-commerce

e-commerce allows for many innovations in pricing: some have been embraced by consumers, others rejected. Using an online experiment, we explore the role of norms in predicting consumer responses to differential pricing arrived at either by violating an established pricing norm (dynamic posted pricing; setting prices based on individual consumer demand) or not (two retailers pricing differently). Our findings support the critical role of norms, such that belief in the norm is a strong predictor of negative responses (i.e., fairness, trust, purchase, search and complaint intentions) and priming people to consider norms generally increases the negative response. We also find that prior trust in the firm acts as a partial buffer against the negative response to norm breaking but at a diminishing rate as prior trust increases.     

Theory for an age of crisis: seeing money as an organizational process

The worldwide financial crisis and the need to understand the conditions leading up to it and the associated responses highlight the importance of money in organizations. Yet, money is undertheorized in management theory and considered uninteresting or “inert” (Mitchel & Mickel, 1999 ). In contrast, related social sciences and organizational practices provide rich insights into the socially contingent and expressive qualities of money. This paper proposes a new multidimensional framework for analyzing money as a social construct and suggests how it can be used to theorize and research the collapse of financial markets and the Great Recession.

Population–Environment Interactions: European Migration, Population Composition and Climate Change

The paper addresses the collision of two twenty-first Century transitions—the unprecedented change in the size, composition, density and distribution of the human population, and rapid change in the earth’s natural environment, in part a response to the above. It argues that it is important to consider these aspects of population change and environment together in order to understand the reality of any mitigation that may be made. Following a review of research which is beginning to address not only the environmental impact of population growth, but also of changes in density, distribution and composition, the paper turns to explore the interaction of population composition and density with environmental change through addressing interactions between migration, ageing populations and climate change. It considers a key population question facing the EU, that of the demographic deficit, and addresses how the mitigating role of migration will be affected by future climate change. It thus considers whether migration is a valid policy approach in the context of Europe’s demographic deficit and the impact of climate change on this relationship.     

Analysis of an integrated maximum covering and patrol routing problem

In this paper, we address the problem of determining the patrol routes of state troopers for maximum coverage of highway spots with high frequencies of crashes (hot spots). We develop a specific mixed integer linear programming model for this problem under time feasibility and budget limitation. We solve this model using local and tabu-search based heuristics. Via extensive computational experiments using randomly generated data, we test the validity of our solution approaches. Furthermore, using real data from the state of Alabama, we provide recommendations for (i) critical levels of coverage; (ii) factors influencing the service measures; and (iii) dynamic changes in routes.
