On the Role of Agent‐based Modeling in the Theory of Development Economics

In this article I discuss the potential role of agent‐based modeling techniques in development economics. Development economics has recently seen a strong rise of experimental evidence from the field and the laboratory. At the same time, there is a debate on how theory should adapt to this new approach and its findings. I argue in this paper that the agent‐based modeling approach is a promising complement to the traditional modeling techniques, as it can easily incorporate the non‐standard findings of the experimental literature. Moreover, I emphasize the opportunity of a mutually beneficial interplay between experiment‐based empirical research and agent‐based models.     

Benford and the Internal Capital Market: A Useful Indicator of Managerial Engagement

We propose the application of digit analysis using the Benford law to indicate managerial engagement in the capital allocation process. First, we motivate the potential of the Benford digit analysis to identify allocation outcomes that are shaped by human engagement instead of fixed decision rules. Second, we provide a case study to illustrate how the Benford digit analysis can be used to detect allocations affected by managerial interventions. We are unaware of any study applying the Benford test to internal capital markets, while this approach appears very useful in this context. It is commonly used in the auditing, financial accounting, and fraud detection literature.     

The relationship between lack of controllability and proactive work behaviour: an empirical analysis of competing theoretical explanations

The controllability principle suggests evaluating managers solely based on performance measures they can control. In practice, however, companies often disregard this principle. Therefore, our study addresses organisational benefits linked to the lack of controllability in measures used for managers’ performance evaluations. We draw on important case-based findings to establish a positive ‘base relationship’ between lack of controllability and proactive work behaviour. We test this base relationship with a large-scale sample and find that companies encourage higher levels of proactive work behaviour when they rely on less controllable performance measures. Drawing on recent developments in role theory, we advance previous research and extend the base model by including the theoretical construct of flexible role orientation. We examine different mechanisms through which flexible role orientation potentially impacts the base model. Using survey responses from 432 managers, we find evidence for a mediation model as opposed to an interaction model. Specifically, we find that lack of controllability enhances role conflict, which in turn induces more flexible role orientations ultimately resulting in higher levels of proactive work behaviour.     

Sequential numerical integration in nonlinear state space models for microeconometric panel data

This paper discusses the estimation of a class of nonlinear state space models including nonlinear panel data models with autoregressive error components. A health economics example illustrates the usefulness of such models. For the approximation of the likelihood function, nonlinear filtering algorithms developed in the time‐series literature are considered. Because of the relatively simple structure of these models, a straightforward algorithm based on sequential Gaussian quadrature is suggested. It performs very well both in the empirical application and a Monte Carlo study for ordered logit and binary probit models with an AR(1) error component.

Employment effects of the Football World Cup 1974 in Germany

This study demonstrates that the Football World Cup 1974 in Germany was not able to generate any medium to long-term employment effects that were significantly different from zero. It is the first work to examine the employment effects of Football World Cup tournaments. It is also the first work to undertake a multivariate analysis of the employment effects of a major sporting event outside of the USA. In addition, this study does not arbitrarily determine the time period for the potential positive effects of a major sporting event but instead examines several alternative periods. Furthermore, the study tests for method sensitivity by analysing the data set in parallel with the approaches used in the studies of sporting events in the USA as well as in a fourth modifying estimation approach. In contrast to the conclusions reached in comparable studies, the results are not regarded as a clear refutation of the positive effects of major sporting events.     

Consumer Information and Discrimination: Does the Internet Affect the Pricing of New Cars to Women and Minorities?

Using a large dataset of automobile transaction prices, we find that offline African-American and Hispanic consumers pay approximately 2% more than do other offline consumers; however, we can explain 65% of this price premium with differences in observable traits such as income, education, and search costs. Our estimates of unexplained race premia are smaller than previous estimates in the literature. Online, we find that minority buyers pay nearly the same prices as do whites controlling for consumers' income, education, and neighborhood characteristics. These results are consistent with the Internet facilitating information search and removing cues to a consumer's willingness to pay. Our results imply that the Internet is particularly beneficial to those whose characteristics disadvantage them in negotiating.     

Uniform Service,Uniform Productivity? Regional Efficiency of the Imperial German Postal,Telegraph, and Telephone Service

Using the regional productivity of the Reichspost, the postal service of the German Empire, I investigate whether a public monopolist operates with uniform regional productivity. Using data envelopment analysis efficiency scores, we derive the relative productivity of the post, telegraph, and telephone sectors from 1891 to 1908. Results show a fairly stable system with substantial raw productivity differences between postal districts, and that the expansion of the service offset technological productivity increases for the mail service.     

TECHNOLOGY TRANSFERS FOR CLIMATE CHANGE

This article considers the transfer of cost‐reducing technology in the context of contributions to climate protection. We analyze a two‐period public goods model where later contributions can be based on better information, but delaying the mitigation effort is costly because of irreversible damages. Investments in technology affect the countries' timing of contributing. We show that countries have an incentive to provide cost‐reducing technology as this can lead to an earlier contribution of other countries and can therefore reduce a country's burden of contributing to the public good. Our results provide a rationale for the support of technology sharing initiatives.     

A providers’ perspective on supplier relationships in performance-based contracting

As companies are concentrating on core competencies, they increasingly require their suppliers to provide full solutions rather than individual offerings. Many of these solutions, a specific one being “performance-based contracting” (PBC), require a systems integration approach from the providers, who strongly depend on their sub-suppliers’ contributions. Yet, while research on PBC is increasing and some implications for the customer–provider relationship have been identified, no study has been undertaken to analyse the implications of PBC on the upstream suppliers, specifically how the relationship is impacted by results-oriented concepts such as PBC, how suppliers are aligned to the PBC outcome and how they participate in the performance-based compensation. This paper seeks to address this gap, combining a theoretical approach and an empirical approach. The challenges resulting from PBC on the supplier relationships of PBC providers are first analysed from an information economics perspective. Then, a case study approach with insights from typical PBC industries such as defence or aerospace was used to validate and enhance the study. The findings show that despite opposing assumptions in previous literature, PBC suppliers are not involved into the concept’s specifics in a dedicated way, giving away the potentials of a proper alignment. Based on this, a governance portfolio model for the PBC providers’ supplier relationships is developed. The paper is concluded with managerial and theoretical implications.
