Unbeatable Imitation

We show that for many classes of symmetric two-player games, the simple decision rule "imitate-the-best" can hardly be beaten by any other decision rule. We provide necessary and sufficient conditions for imitation to be unbeatable and show that it can only be beaten by much in games that are of the rock-scissors-paper variety. Thus, in many interesting examples, like 2x2 games, Cournot duopoly, price competition, rent seeking, public goods games, common pool resource games, minimum effort coordination games, arms race, search, bargaining, etc., imitation cannot be beaten by much even by a very clever opponent

Emotions and scope effects in the monetary valuation of health

JEL classifications: H41 H51 I11 I18 I31This study presents evidence on the role of emotions in the monetary evaluation of health technologies, namely, drug-eluting stents (DES) in our case. It is shown that subjects who are very afraid of having to undergo an angioplasty are: (a) less sensitive to the size of the risk reduction provided by DES and (b) willing to pay more. The lack of scope sensitivity questions the normative validity of the responses of highly emotional subjects. We provide evidence of this effect using what we call the cognitive-emotional random utility model and the responses of a face-to-face, computer-assisted personal interview survey conducted in a representative sample of the Spanish general population (n = 1663).3253150,9922,169Q1Q1SSC

Financial constraints and the decision to lease : evidence from German SME

The objective of this paper is to test the hypothesis that in particular financially constrained firms lease a higher share of their assets to mitigate problems of asymmetric information. The assumptions are tested under a GMM framework which simultaneously controls for endogeneity problems and firms' fixed effects. We find that the share of total annual lease expenses attributable to either finance or operating leases is considerably higher for smaller firms with higher average interest rates and high-growth firms - those likely to face higher agency-cost premiums on marginal financing. Furthermore, our results confirm the substitution of leasing and debt financing for lessee firms. However, we find no evidence that firms use leasing as an instrument to reduce their tax burdens.

Combining and Comparing Consumers' Stated Preference Ratings and Choice Responses

In this study we develop and test an econometric model for combining choice and preference ratings data collected from the same set of individuals.Choice data are modeled using a multinomial logit framework, while preference data are modeled using an ordered response equation.Individual heterogeneity is allowed for via random coefficients providing a link between the choice and ratings data.Parameters are estimated by Simulated Maximum Likelihood.An application of the model to consumer yoghurt choice in The Netherlands found that ratings based preference estimates differ significantly from choice based estimates, but the correlation between random coefficients driving the two is very strong.econometric models;preferences;consumer choice;maximum likelihood;JEL classifications;C35;M31

Innovation and Economic Growth in European Union. Panel Data Analysis

JEL Classifications: O33, O30, O47This study examines the relationship between technological innovation and economic growth in European Union countries over the period 1993-2011. Using Blundell and Bond (1998) generalized method of the moments estimation technique, the study provides evidence that R&D expenditures and patent activities differ in terms of fostering economic growth between EU-15 and EU-13 countries. The main results indicate that there is no significant impact of R&D expenditures on the economic growth and that patent activities determine economic growth in EU-13 subsample and EU-28 as a whole. The study suggests that there may be no one particular recipe for growth for all EU countries and put into question whether setting common numerical targets in EU’s innovation policy makes economic sense

The impact of business process outsourcing on firm performance and the influence of governance : a long term study in the German banking industry

Does BPO pay off at the firm-level? Although there are several studies which analyze the potential benefits of BPO, there is a virtual absence of research papers on BPO outcomes. Based on an analysis of 137 Business process outsourcing (BPO) ventures at 254 German banks in a period between 1994 and 2005, we found that the outsourcer's financial performance in terms of profitability and cost efficiency was increased significantly compared to industry peers without BPO. The increase stems not from workforce reductions but rather from increased employee productivity. Further, we show how BPO governance ensures BPO success: individually negotiated outsourcing contracts help to improve cost efficiency and profitability measures. Relational governance based on trust has only positive effects on profitability.

The Contribution of Pollution to Productivity Growth.

In this paper we examine the effect of pollution, as measured by CO2 emissions, on economic growth among a set of OECD countries during the period 1981-1998. We examine the relationship between total factor productivity (TFP) growth and pollution using a semiparametric smooth coefficient model that allow us to directly estimate the output elasticity of pollution. The results indicate that there exists a nonlinear relationship between pollution and TFP growth. The output elasticity of pollution is small with an average sample value of 0.008. In addition we find an average contribution of pollution to productivity growth of about 1 percent for the period 1981-1998.

Public libraries and political participation, 1870-1940

The public library movement of the late 19th and early 20th centuries fostered a rapid increase in the number and quality of public libraries in cities and towns across the United States. One important argument for libraries was that they would enhance American democracy by promoting virtues of citizenship and enabling access to information. This paper examines how voter turnout was affected, in the short-term, by the establishment of public libraries, using a county-by-election year panel. Our empirical strategy exploits the founding dates of public libraries as discrete events that should have influenced subsequent voting behavior. Over the wide range of specifications considered, the vast majority of regression results suggest that libraries had no significant short term impact on voter turnout. We discuss potential reasons for this finding, and compare it with recent work finding a positive impact of newspapers on political participation. JEL classifications: H40, H75, N31, N32, N41, N4
