Limited investor attention and the mispricing of American Depositary Receipts

I test whether more investor attention leads to a better exploitation of arbitrage opportunities and, in turn, to less mispricing of American Depositary Receipts (ADRs). Using data on 536 stocks I find that more investor attention significantly reduces ADR mispricing.     

Does the ECB act as a lender of last resort during the subprime lending crisis?: Evidence from monetary policy reaction models

We investigate whether the ECB aligns its monetary policy with financial crisis risk in EMU member countries. We find that since the outbreak of the subprime crisis the ECB has significantly increased net lending and reduced interest rates when banking and sovereign debt crisis risk in vulnerable EMU countries (Greece, Ireland, Italy, Portugal, and Spain) increases, while no significant effect is identified for the pre-crisis period and relatively tranquil EMU countries (Austria, Belgium, France, Germany, and the Netherlands). These findings suggest that the ECB acts as a Lender of Last Resort for vulnerable EMU countries.     

Unemployment and debt dynamics in a highly indebted small open economy

The paper analyzes the dynamic effects of a total factor productivity shock and an interest rate risk premium shock in a highly indebted open economy. In contrast to the standard open economy framework, search unemployment and wage bargaining are introduced. We find that a negative total factor productivity shock primarily has effects on the economy's production side and on welfare, but not on its stock of foreign debt and the country specific risk premium, and large part of the adjustment happens in the short-run. In contrast, a pure increase in the country specific risk premium causes substantial dynamics and a considerable reduction in foreign debt, allowing higher consumption in the long run and creating an intertemporal welfare gain, even though unemployment increases strongly in the short-run. A 50% haircut of foreign debt significantly reduces the initial response of the unemployment rate. In case of a temporary productivity shock, sticky wages imply smaller employment, but generate higher welfare than flexible wages.     

Growth and convergence in South–South integration areas: An empirical analysis

Until recently, it has been argued in economic theory that regional integration and trade agreements among developing countries may achieve negative growth effects. This study tests empirically the effects of such South–South agreements on growth and convergence. All three world regions in question are considered: South America, Southeast Asia, and Sub‐Saharan Africa. A comprehensive panel data analysis is conducted that distinguishes between the problems of testing for stronger growth and accelerated convergence, respectively. The data indicate that the considered South–South agreements promote both.     

Good Consumer Information: the Information Paradigm at its (Dead) End?

The traditional information paradigm postulates that increasing the amount of information and establishing full transparency help consumers with their decisions. We challenge this assumption and address criteria that good consumer information needs to fulfil. Based on the findings from research in behavioural economics and finance, necessary conditions for good consumer information include transparency, comprehensibleness, and comparability, whereas quality—in terms of clarity, fit to personal needs, and verifiability—represents the sufficient condition for good consumer information. Information that consumers currently receive hardly fulfils these conditions which, in turn, considerably hampers the trustworthiness and usability of this information. To mitigate consumers’ information problem and to recover the idea of the information paradigm, we suggest to extend the information model and to integrate the idea of collective consumers, to establish product testing principles, and to implement controlled minimum standard for (financial) products.     

Aufschwung in Deutschland weiter kräftig — Anspannungen nehmen zu

The business cycle upswing in Germany has gained strength and breadth. In addition to private consumption, the expansion is now also supported by investment and foreign trade. The latter benefits from growing exports to the euro area, where the economy is gaining momentum. Since the euro area upswing rests on solid fundamentals, the ECB should be able to start tapering without putting the economy at risk.     

Collective Choices Under Ambiguity

We investigate experimentally whether collective choice environments matter for individual attitudes to ambiguity. In a simple two-urn Ellsberg experiment, one urn offers a 45 % chance of winning a fixed monetary prize while the other offers an ambiguous chance. Participants choose either individually or in groups of three. Group decision rules vary in the level of individual responsibility for the others’ payoffs: the collective choice is taken by majority, randomly delegated to two group members, or randomly delegated to a single group member. Although most participants display consistent ambiguity attitudes across their decisions, taking responsibility for the others tends to foster ambiguity aversion.     

Novel advancements in the Markov chain stock model: analysis and inference

In this paper we propose further advancements in the Markov chain stock model. First, we provide a formula for the second order moment of the fundamental price process with transversality conditions that avoid the presence of speculative bubbles. Second, we assume that the process of the dividend growth is governed by a finite state discrete time Markov chain and, under this hypothesis, we are able to compute the moments of the price process. We impose assumptions on the dividend growth process that guarantee finiteness of price and risk and the fulfilment of the transversality conditions. Subsequently, we develop non parametric statistical techniques for the inferential analysis of the model. We propose estimators of price, risk and forecasted prices and for each estimator we demonstrate that they are strongly consistent and that properly centralized and normalized they converge in distribution to normal random variables, then we give also the interval estimators. An application that demonstrate the practical implementation of methods and results to real dividend data concludes the paper.
