Are impatient farmers more risk-averse? Evidence from a lab-in-the-field experiment in rural Uganda

Based on data from a field-experiment in rural Uganda, we show that impatient farmers are more risk-averse than patient farmers. We relied on a simplified version of the Convex Time Budget (CTB) method to elicit farmers’ time preferences and on an independent method for eliciting their risk-preferences. We report two important findings. First, we show that our simplified CTB method applied to farmers from Uganda replicates the key findings of Andreoni and Sprenger’s lab experiments that involved student subjects. Second, we establish the existence of a negative correlation between risk tolerance and impatience, based on two independent measures.     

Home sweet host: A cross‐country perspective on prudential and monetary policy spillovers through global banks

Prudential regulation of banks is multi‐layered: policy changes by home‐country authorities affect banks’ global operations across many jurisdictions; policy changes by host‐country authorities shape banks’ operations in the host jurisdiction regardless of the nationality of the parent bank. Do these policies create (unintended) cross‐border spillovers? Similarly, monetary policy actions by major central banks may also have effects on the behaviour of banks in other countries. This paper examines the effect that changes in home‐ and host‐country prudential measures have on cross‐border dollar credit provision, and how these interact with US monetary policy. We first run panel regressions with both layers of regulation, to examine which has a greater effect on cross‐border lending. We then use a novel approach to decompose growth in cross‐border bank lending into separate home, host and common components, and then match each with the corresponding home or host policies. Our results suggest that prudential policies can have spillover effects, which depend on the instrument used and on whether a bank's home or host country implemented them. Home policies tend to have larger spillovers on cross‐border US dollar lending than host policies. We also find that a tightening of US monetary policy can compound the spillovers of some prudential measures.     

Productivity Dispersion and Measurement Error

Several reasons have been put forward to explain the high dispersion of productivity across establishments: quality of management, different input usage and market distortions, to name but a few. Although it is acknowledged that a sizable portion of productivity dispersion may also be due to measurement error, little research has been devoted to identifying how much they contribute. We outline a novel procedure for identifying the role of measurement error in explaining the empirical dispersion of productivity across establishments. The starting point of our framework is the errors-in-variable model consisting of a measurement equation and a structural equation for latent productivity. We estimate the variance of the measurement error and subsequently estimate the variance of the latent productivity variable, which is not contaminated by measurement error. Using Norwegian data on the manufacture of food products, we find that about one percent of the measured dispersion stems from measurement error.     

International Capital Flows in the Model with Limited Commitment and Incomplete Markets

Recent literature has proposed two alternative types of financial frictions, i.e., limited commitment and incomplete markets, to explain the empirical patterns of international capital flows between developed and developing countries in the past two decades. This paper integrates these two frictions into a two-country overlapping-generations framework to facilitate a direct comparison of their respective effects. In our model, limited commitment distorts the investment made by agents with different productivity, which creates a wedge between the interest rates on equity capital vs. credit capital; while incomplete markets distort the investment among projects with different riskiness, which creates a wedge between the risk-free rate and the mean rate of return to risky capital. We show that the two approaches are observationally equivalent with respect to their implications for international capital flows, production efficiency, and aggregate output.     

What’s at Stake in Securitising Climate Change? Towards a Differentiated Approach

Climate change has been successfully represented as a security concern to such an extent that it is firmly established on the political agenda, even though the implementation of concrete policies is disputed. In this paper, we develop an analytical framework to better trace the process of securitising climate change and assess its normative implications. We establish a typology of six climate security discourses on the basis of two dimensions: three levels of referent objects and two logics of securitisation, one that corresponds to the original Copenhagen School framework and one where the threat takes the form of the invocation of risk. We find that there are significant differences in the relative importance of the resulting climate security discourses in Germany and the US, but that normatively, all discourses come with their own problems, which calls for more detailed scrutiny and assessment of climate security discourses and their political effects.     

Mehrwert für die Marke durch Kommunikation schaffen

Marken ohne Mehrwert haben keine Existenzberechtigung. Nicht immer liegt der Mehrwert jedoch im Produkt oder der Dienstleistung selbst. Vielmehr kann die Kommunikation selbst einen Mehrwert für Marken schaffen. Deshalb wird im folgenden Beitrag gezeigt, wie man den Markenmehrwert einerseits klar kommunizieren und andererseits durch die Kommunikation selbst Mehrwert zum Nutzen für den Kunden und für das Unternehmen schaffen kann.     

Intended brand associations: Do they really drive consumer response?

Brand managers exhibit considerable effort to define intended brand associations to anchor in consumers' minds. They follow a credo deeply rooted in branding literature: intended brand associations drive consumer response and brand equity. This article investigates the benefits of a strong overlap of actual consumer brand associations and management-intended brand associations (brand association match). The article presents results from two large-scale studies (3353 and 1201 respondents) involving one consumer goods and one service brand with multiple operationalizations of consumer response (attitudinal and behavioral). The results show that consumers with high brand association match show more positive brand response. However, after accounting for the valence of associations match does not add explanatory power. This outcome challenges a key foundation of brand management. The discussion identifies reasons why match may not be necessary to achieve response and provides arguments why the results do not imply free play for brand managers.     

The taxation of bonuses and its effect on executive compensation and risk‐taking: Evidence from the UK experience

This paper explores the effects of a bonus tax adopted in the UK in December 2009 on the compensation structure of executives and on risk‐taking behavior in the financial sector. Excessive bonuses are blamed for encouraging risk taking and are regarded as one of the pull factors of the financial crisis. The British government attempted to reduce bonuses and accordingly bank risk taking by means of a special tax on cash‐based bonuses. Using a comprehensive dataset on executive compensation, we show that the introduction of the bonus tax decreased the net cash bonuses awarded to directors by about 40%, accompanied, however, by a simultaneous increases in other forms of pay leaving total compensation as well as risk levels unaffected.     

Ruin probabilities expressed in terms of ladder height distributions

Abstract

During the latest few years much attention has been given to the study of the ruin problem of a risk business when the epochs of claims form a renewal process. The study of this problem was initiated by E. S. Andersen (1957). Thorin has then in a series of papers (Thorin, 1970, 1971a, 1971b) shown that the Wiener-Hopf technique, originally developed by Cramer (1955) in the case of a Poisson process, can be used in this more general case, and Takacs (1970) has derived results similar to those of Thorin by an entirely new technique.
