The Impact of Firing Costs on Turnover and Unemployment: Evidence from the Colombian Labour Market Reform

Reductions in firing costs are often advocated as a way of increasing the dynamism of labour markets in both developed and less developed countries. Evidence from Europe and the U.S. on the impact of firing costs has, however, been mixed. Moreover, legislative changes both in Europe and the U.S. have been limited. This paper, instead, examines the impact of the Colombian Labour Market Reform of 1990, which substantially reduced dismissal costs. I estimate the incidence of a reduction in firing costs on worker turnover by exploiting the temporal change in the Colombian labour legislation as well as the variability in coverage between formal and informal sector workers. Using a grouping estimator to control for common aggregate shocks and selection, I find that the exit hazard rates into and out of unemployment increased after the reform by over 1\% for formal workers (covered by the legislation) relative to informal workers (uncovered). The increase of the hazards implies a net decrease in unemployment of a third of a percentage point, which accounts for about one quarter of the fall in unemployment during the period of study.     

A note on distortions from estimating the regional impacts of exogenous changes in output

This paper demonstrates both theoretically and empirically that when outputs instead of final demands are exogenously predetermined, the traditional Leontief final demand model overestimates economic impact, and even more so in a multiregional context. We assess this premise vis-à-vis the Leontief output model using the 2013 interregional input–output table of the Republic of Korea. We find that from a multiregional perspective the standard Leontief final demand model yields substantially biased output multipliers for Chungbuk Province.

Behavioural Bias and Conflicts of Interest in Analyst Stock Recommendations

Abstract:  This paper tests whether sell-side analysts are prone to behavioural errors when making stock recommendations as well as the impact of investment banking relationships on their judgments. In particular, we analyse their report narratives for evidence of cognitive bias. We find first that new buy recommendations on average have no investment value whereas new sell recommendations do, and take time to be assimilated by the market. We also show that new buy recommendations are distinguished from new sells both by the level of analyst optimism and representativeness bias as well as with increased conflicts of interest. Successful new buy recommendations are characterised by lower prior returns, value stock status, smaller firms and weaker investment banking relationships. On the other hand, successful new sells do not differ from their unsuccessful counterparts in terms of these measures. As such, we provide evidence that analysts are prone both to behavioural bias as well as potential conflicts of interest in their new buy stock recommendation decisions. We also show that these two explanations of analyst behaviour are to a great extent independent of each other. Consequently, the recent attempts by regulators to address potential conflicts of interest in analyst behaviour may have only limited impact.     

Corporate greening through prosocial extrarole behaviours – a conceptual framework for employee motivation

Scholars in environmental management have called for better grounding of research on corporate greening within established organizational theories. We propose a conceptual framework (including suggestions for operationalizing it) that embeds empirical research within behavioural intent models and the concept of value‐creating prosocial behaviours. We argue that conceiving of corporate greening as a prosocial behaviour in this manner provides an improved understanding of the dominant factors that motivate employees to engage in ecoinitiatives.

Output and Input Biases Caused by Public Agricultural Research and Extension in Japan, 1957–1997

The present paper investigates the magnitude and the Hicksian output and input biases of technological change brought about by investments in public agricultural research and extension activities in Japan. Given this objective, it estimates a translog multiproduct cost function for 1957–1997. Empirical results show that the cost reduction effects were fairly large. The Hicksian (1932) biases were found to be: (i) livestock-augmenting; (ii) labor- and other-inputs-saving; and (iii) machinery- and intermediate-inputs using. Except for other inputs, the directions of the biases are consistent with the Hicksian (1932) induced innovation hypothesis, which supports the public-sector-induced-innovation model proposed by Hayami and Ruttan (1985) and Ohtsuka (1982).     

Investor attention, overconfidence and category learning

Motivated by psychological evidence that attention is a scarce cognitive resource, we model investors’ attention allocation in learning and study the effects of this on asset-price dynamics. We show that limited investor attention leads to category-learning behavior, i.e., investors tend to process more market and sector-wide information than firm-specific information. This endogenous structure of information, when combined with investor overconfidence, generates important features observed in return comovement that are otherwise difficult to explain with standard rational expectations models. Our model also demonstrates new cross-sectional implications for return predictability.     

Learning lessons: how to practice nudging around the world

Abstract

The aim of this article is to cover three things: (1) to introduce the context behind why a report prepared by the Organisation for Economic Co-operation and Development (OECD) in 2017 would be of such importance to researchers in various academic disciplines and public policy, (2) to present the details of a simple classification system that was applied to all 111 case studies of behavioural interventions (better known as nudges) referred to in the OECD (2017a OECD. 2017a. Behavioural Insights and Public Policy Lessons from Around the World.1-408 pp. OeCD Publishing. https://read.oecd-ilibrary.org/governance/behavioural-insights-and-public-policy_9789264270480-en. doi:10.1787/9789264270480-en.[Crossref] , [Google Scholar]) report, and (3) to discuss what needs to be done to help advance practitioners’ pursuit of effective behavioural interventions. This article aims to highlight the importance of accurately cataloguing the types of behavioural interventions that have been trialled/implemented across the world. By adopting an agreed classification system, researchers and practitioners can benefit from knowing what can work, and where it can work, as well as what does not work, in order to be better armed when considering the use of behavioural interventions to solve social policy issues.     

Predicting season ticket holder loyalty using geographical information

Season ticket holders (STHs) are an integral part of the sporting product. Interestingly, and contrary to the persistent interest in analysing the determinants of stadium attendances, sports economists have so far largely refrained from exploring the potential determinants of STH loyalty as expressed through regular stadium attendances. In this article, we address this notable shortcoming by exploring the potential determinants of STH stadium attendance demand. In particular, we examine the yet under-researched role of increasing opportunity costs resulting from larger home-stadium distances in STH stadium attendance demand. Our results suggest that STHs’ geographical location plays an important role in predicting STH stadium attendance demand. More specifically, we observe an unexpected, nonlinear distance–attendance relationship, indicating that behaviourally loyal STHs live either exceptionally close or far away from the stadium.
