Between mathematical formalism,normative choice rules,and the behavioural sciences: The emergence of rational choice theories in the late 1940s and early 1950s

Abstract

This paper discusses why mathematical economists of the early Cold War period favored formal-axiomatic over behavioral choice theories. One reason was that formal-axiomatic theories allowed mathematical economists to improve the conceptual and theoretical foundations of economics and thereby to increase its scientific status. Furthermore, the separation between mathematical economics and other behavioral sciences was not as clear-cut as often argued. While economists did not modify their behavioral assumptions, some acknowledged the empirical shortcomings of their models. The paper reveals the multifaceted nature of rational choice theories reflected in the changing interpretations and roles of the theories in those early years.     

A Contingent Valuation Estimate of the Benefits of Wolves in Minnesota

In this paper we estimate the willingness topay for a wolf management plan and a wolfdamage plan in Minnesota using the contingentvaluation method. The theoretical definition ofwillingness to pay for wolf protection iscomposed of use and non-use values. Weincorporate a don't know response option in thedichotomous choice valuation questions. A largenumber of respondents answered don't know. Themultinomial logit model is used todifferentiate between don't know and noresponses. Non-use motives are importantfactors that explain willingness to pay. We usethese benefit estimates in combination with twoalternative cost estimates to consider theefficiency of the wolf management and damageplans. Both plans have estimated benefitsgreater than costs.     

How are Scope and Adding up Relevant for Benefits Transfer?

In this paper, we explore ways in which the theoretical constructs of scope and adding up can inform and improve the practice of benefit transfer. Specifically, we examine how the stated preference literature on scope and adding up can inform three critical steps in benefits transfer: study site selection, including studies to select for use in a meta-regression; calibrating benefit functions; and assessing transfer validity.     

Transmission of information within transnational social networks: a field experiment

Several studies have shown a relationship between the stocks of migrants and country-level investment in the home country; however the mechanism through which this relationship operates is still unexplored. We use a field experiment in which participants who are recent immigrants send information about risky decisions to others in their social network in their home country. The results demonstrate how this information influences decisions in the home country. We find that the advice given by family members and decisions made by friends significantly affects an individual’s risky decision-making.     

HOW DO SPOUSES SHARE THEIR FULL INCOME? IDENTIFICATION OF THE SHARING RULE USING SELF‐REPORTED INCOME

The paper applies the collective model to the analysis of intra-household inequality using one of the subjective-qualitative questions available in the RLMS (Russia Longitudinal Monitoring Survey) data, and provides a test for its assumptions. Interpreting the individual answers as reported budget scales we assume a correspondence between the budget level that household members report and their true income sharing. We first show that this assumption is supported by the data, and then use couples who report the same level of budget to identify the full sharing rule for the whole sample.     

The impact of information signals on market prices when agents have non-linear trading rules

Several methods have been developed for filtering seasonal influences and extreme returns in financial and economic time series. The theoretical support for these approaches is rather questionable since it focuses on the effects of shocks on prices and not on their sources. Removing such effects modifies the true generating system of market dynamics because of the non-proportional character of non-linearity. Thus, taking into account that the underlying process of economic time series is highly non-linear we cannot be certain a priori what the impact of new information will be on the dynamic structure of a system. The main contribution of this paper is to demonstrate using the methodology of simulations the eventual distortions in time series data arising from the arrival of news when agents follow non-linear trading strategies. We argue that if news can really modify the dynamical behaviour of a system, then the methodology of filtering exogenous distortions needs to be re-examined.     

Fuzzy Chronic Poverty: A Proposed Response to Measurement Error for Intertemporal Poverty Measurement

A number of chronic poverty measures are now empirically applied to quantify the prevalence and intensity of chronic poverty, vis‐à‐vis transient experiences, using panel data. Welfare trajectories over time are assessed in order to identify the chronically poor and distinguish them from the non‐poor, or the transiently poor, and assess the extent and intensity of intertemporal poverty. We examine the implications of measurement error in the welfare outcome for some popular discontinuous chronic poverty measures, and propose corrections to these measures that seeks to minimize the consequences of measurement error. The approach is based on a novel criterion for the identification of chronic poverty that draws on fuzzy set theory. We illustrate the empirical relevance of the approach with a panel dataset from rural Ethiopia and some simulations.     

The evolution of the monetary transmission channels in Turkey: evidence from a TVP-VAR model

This article investigates the evolution of the monetary transmission mechanisms in Turkey for the period from January 1986 to December 2016. To this aim, the impacts of monetary variables on the prices and economic activity are investigated with a time-varying vector autoregressive model based on. The evidences from the time-varying responses indicate that the adoption of inflation targeting policy has markedly affected the functioning of transmission channels. The results also suggest that local and global financial crises may magnify the impact of monetary policy shocks on the overall economy.     

A Hausman-type test to detect the presence of influential outliers in regression analysis

In regression analysis, classical estimations may be excessively influenced by a few atypical observations. We propose a Hausman-type test to balance robustness and efficiency and to check whether a robust method should be implemented. An economic application is presented.
