On the evolutionary edge of altruism: a game-theoretic proof of Hamilton’s rule for a simple case of siblings

We offer a game-theoretic proof of Hamiltons rule for the spread of altruism. For a simple case of siblings, we show that the rule can be derived as the outcome of a one-shot prisoners dilemma game between siblings.JEL Classification: A13, C70, D64Correspondence to: Oded Stark, ZEF, University of Bonn, Walter-Flex-Strasse 3, 53113 Bonn, GermanyWe are indebted to an anonymous referee and to Uwe Cantner for helpful comments and suggestions.

Decentralized planning in a market economy? On the nature of Coase’s research program

By drawing attention to the planning islands of firm organizations in a market economy, Coase makes us believe that besides the price mechanism, there is another means of coordination, namely deliberate coordination. With the firm as an exemplary case of deliberate coordination was introduced into landscape of economics, Coase initiated a new research program which is to inquire into how efficiency is (and could be) achieved via various kinds of institutional arrangements, from the price mechanism, to firms, to government regulations. This paper acknowledges the positive role Coase has played in drawing economists’ attention to the generally neglected field of organizational research. It criticizes, however, his research program for viewing the economy, or society, from the perspective of some concrete decision-making entity.     

On the Neutrality of Profit Taxation in a Mixed Oligopoly

This paper investigates the neutrality of profit taxation in a mixed oligopoly where one (partially) public firm competes with private firms. We find that the neutrality of a profit tax is robust under a general cost and a general demand function as long as the degree of privatization is endogenously determined. This result is also true when product heterogeneity is considered under both Cournot and Bertrand competition. By contrast, if the degree of privatization is exogenously given, the profit tax neutrality holds only in the cases where the public firm is fully privatized or fully state-owned; otherwise, the neutrality breaks down.     

A bibliometric account of the evolution of EE in the last two decades: Is ecological economics (becoming) a post-normal science?

In ecological economics the debate on formalism and formalization has been addressed in the context of a lively discussion on ecological economics as a ‘post-normal’ (versus ‘normal’) science. Using ecological economics (EE) as a ‘seed’ journal and applying bibliometric techniques to all (2533) the articles published in EE from January 1989 to December 2009, we analyze the evolution of the field of ecological economics aiming to shed light on this debate. We observe the predominance (and increased relevance) of certain research topics: ‘Methodological issues’, ‘Policies, governance and institutions’ and ‘Valuation’. Moreover, ‘Collective action’, ‘Technical change and the environment’ and ‘Values’ stand as emergent themes of research. Finally, we note that ecological economics experienced an ‘empirical turn’ reflected in a shift away from exclusively formalized papers towards exclusively empirical and, to a larger extent, ‘formal and empirical’ ones. The combination of the prominent and emergent topics and the ‘empirical turn’ mirrors the increasing awareness among researchers in the field of the need to address a key specificity of ecological economics — the interdependence of the economic, biophysical and social spheres. On this basis, we argue that at least through the lens of EE, ecological economics has evolved towards a post-normal science.     

On the incentive effects of monitoring: evidence from the lab and the field

Several experimental studies have shown that the crowding-out effect of monitoring may outweigh its disciplining effect through intrinsic motivation destruction, thereby reducing effort. However, most of these experiments use numeric effort tasks that subjects may not be intrinsically motivated to complete. This paper aims to analyze the incentive effects of monitoring using a real-effort task for which intrinsic motivation is more likely to exist. We conducted two similar experiments, in the lab in Montreal and in the field in Ouagadougou. In contrast to the lab, subjects in the field are unaware they are taking part in an experiment.     

Shadows of the past: path dependence of TV on its sub-systems,complements and substitutes

In this study, two levels of path dependence in the television technological system are examined: (1) How does the development of television (TV) core components affect the development of peripheral components? and (2) How does the development of complementary and substitute technologies affect the development of television technology? Results from the empirical analysis using patents from 1975 to 2004 indicate that: (a) the development of TV periphery technologies is path-dependent on the development of TV core technologies and (b) even after controlling for its own prior history, the development of the TV system is path-dependent on the development of its complementary technologies. However, there is weak evidence of the path dependence of the TV system on the development of its substitute technologies.     

On the monetary nature of the interest rate in a Keynes–Schumpeter perspective

Abstract

Keynes, in the General Theory, explains the monetary nature of the interest rate by means of the liquidity preference theory. The objective of this article is twofold. The first objective is to point out the limits of the liquidity preference theory. The fundamental limitation of this theory is that it does not allow to realize the intent declared by Keynes in 1933 to elaborate a monetary theory of production The second objective is to present a more solid theory of the monetary nature of the interest rate. It will be shown that an essential element of this explanation is Schumpeter’s analysis of the role of bank money in a capitalist economy. In fact, this analysis represents a fundamental tool to explain the characteristics that, according to Keynes, distinguish a monetary economy from a real-exchange economy     

An evolutionary edge of knowing less (or: On the ‘curse’ of global information)

Consider a population of farmers who live around a lake. Each farmer engages in trade with his two adjacent neighbors. The trade is governed by a prisoner’s dilemma ‘rule of engagement.’ A farmer’s payoff is the sum of the payoffs from the two prisoner’s dilemma games played with his two neighbors. When a farmer dies, his son takes over. The son decides whether to cooperate or defect by considering the actions taken and the payoffs received by the most prosperous members of the group comprising his own father and a set of his father’s neighbors. The size of this set, which can vary, is termed the ‘span of information.’ It is shown that a larger span of information can be detrimental to the stable coexistence of cooperation and defection, and that in well-defined circumstances, a large span of information leads to an end of cooperation, whereas a small span does not. Conditions are outlined under which, when individuals’ optimization is based on the assessment of less information, the social outcome is better than when optimization is based on an assessment of, and a corresponding response to, more information.     

The growth–distribution nexus in a mixed regime of education with a status motive: On the macroeconomics of the welfare state

We develop a growth model with human capital accumulation to study the effects of status-driven motivation on individuals' choice between public or private education. This choice interacts with and exacerbates the effects of status, with implications for growth and distribution. More motivated individuals work harder and choose private education. In a majority voting/median voter setup, individuals choose a public education size for which there is no trade-off between long-term growth and inequality. We also highlight the conflict of interest between individuals with respect to the size of the public education sector and the tax rate that supports it. We thus highlight important interactions between the macroeconomy, social attitudes and educational institutions and derive results of interest in a variety contexts. We end by drawing policy conclusions among which, the idea that in democracies, higher growth and lower inequality are mutually compatible when the government promotes public education.     

Price cap regulation: what have we learned from 25 years of experience in the telecommunications industry?

Price cap regulation (PCR) has now been employed in the telecommunications industry for more than a quarter century. We review the experience with PCR and offer an explanation for its popularity. PCR’s design flexibility, its ability to limit undesirable strategic behavior, declining industry costs, and developing competition all enhanced the appeal of PCR. We also review some surprises that have arisen under PCR and discuss the implications of the experience with PCR in the telecommunications industry for regulatory policy in other industries.     

Is external research assessment associated with convergence or divergence of research quality across universities and disciplines? Evidence from the PBRF process in New Zealand

ABSTRACT

Performance-based research evaluations have been adopted in several countries both to measure research quality in higher education institutions and as a basis for the allocation of funding across institutions. Much attention has been given to evaluating whether such schemes have increased the quality and quantity of research. This paper examines whether the introduction of the New Zealand Performance-Based Research Fund process produced convergence or divergence in measured research quality across universities and disciplines between the 2003 and 2012 assessments. Two convergence measures are obtained. One, referred to as β-convergence, relates to the relationship between changes in average quality and the initial quality level. The second concept, referred to as σ-convergence, relates to the changes in the dispersion in average research quality over time. Average quality scores by discipline and university were obtained from individual researcher data, revealing substantial β- and σ-convergence in research quality over the period. The hypothesis of uniform rates of convergence across almost all universities and disciplines is supported. The results provide insights into the incentives created by performance-based funding schemes.     

Tackling Keynes’ question: a look back on 15 years of Learning To Consume

Two centuries of continuous economic growth since the industrial revolution have fundamentally transformed consumer lifestyles. Here Keynes raised an important question: will consumption always continue to expand in the same manner as it has in the previous two centuries? If so, how? This paper critically reviews a body of work that has adopted the Learning To Consume (LTC) approach to study the long run growth of consumption (Witt 2001). By borrowing certain established insights from psychology and biology about how consumers learn and what motivates them to consume, it highlights how rising income, new technologies and market competition have combined to trigger important changes in both the underlying set of needs possessed by consumers and how they learn to satisfy these needs. Methodological issues and open questions are discussed.     

Markups in the Euro area and the US over the period 1981–2004: a comparison of 50 sectors

This article provides estimates of price–marginal cost ratios or mark-ups for 50 sectors in eight Euro area countries and the US over the period 1981–2004. The estimates are obtained applying the methodology developed by Roger (J Polit Econ 103:316–330, 1995) on the EU KLEMS March 2007 database. Five stylized facts are derived. First, perfect competition can be rejected for almost all sectors in all countries; markup ratios are generally larger than 1. Second, average markups are heterogeneous across countries. Third, markups are heterogeneous across sectors, with services having higher markups on average than manufacturing. Fourth, services sectors generally have higher markups in the euro area than the US, whereas the pattern for manufacturing is the reverse. Fifth, there is no evidence that there is a broad range change in markups from the 1980s to the 1990s.     

On the assessment of the performance in earnings management for the banking industry: the case of China’s banks

Earnings management is popular in the banking industry. Earnings can be manipulated by discretionary loan loss provisions (DLLP). Analysing the trajectories of banks’ DLLP (i.e. their change in DLLP over time) is an effective way to assess the performance in earnings management for the banking industry, but seems not to have been addressed in the earnings management literature. In this study, we analyse the trajectories of DLLP with the yearly data from 2007 through 2012 for four types of banks in China. The results have indicated that state-owned banks, policy banks and city commercial banks seem to manage earnings well. Cautionary notes about bank risks are provided.     

Ukraine's unconsidered losses from the annexation of Crimea: What should we account for in the DCFTA forecasts?

In March 2014 Crimea unilaterally declared its independence from Ukraine and joined the Russian Federation. The separation of a part of a state's territory and economy is an interesting matter to examine. The economy of Ukraine has not only shrunk, but also changed its structure as Crimea had a quite distinct production pattern compared to the rest of Ukraine. Moreover, policy measures initialized before the separation may have different effects once applied only to a part of the former economy. This paper proposes a strategy to model the separation of part of an economy and its inclusion into another country and applies this strategy to the case of Crimea, Ukraine, and Russia. Having constructed a model for the new geographical and economic situation, we reinvestigate the possible effects of a Deep and Comprehensive Free Trade Agreement between Ukraine and the EU and compare the results for the situation with Crimea as part of Ukraine. We find that the annexation of Crimea leads to severe economic losses for Ukraine which are partly overproportional compared to Crimea's economic size. These negative effects can be compensated by implementing the DCFTA with the EU as we also show in our model results.     

Catch-up strategy of latecomer firms in Asia: a case study of innovation ambidexterity in PC industry

ABSTRACT

Over the last decade, more and more East Asian firms have moved beyond imitation and are delivering innovative products and services to the market. This study examines (a) how a latecomer firm in East Asia transformed its business model in pursuit of manufacturing its own brand and (b) how it managed its exploration and exploitation of the market and technology in response to growth and competition. Given the lack of research on firms transitioning from contract manufacturing (CM) to own-brand manufacturing (OBM), this study offers fresh insights into how Acer, a leading Taiwanese original equipment manufacturer (OEM), has pursued new ways of creating value using an innovation ambidexterity strategy to maximise its customer value and boost performance.

Acer is chosen for this case study because of its significance and impact in the global PC industry. Data were collected through interviews and secondary data analysis. Our findings show that innovation ambidexterity is a deliberate transition process, taking firms years to reshape their business models. Our findings also present a viable solution to sustainable competitive advantage and keys to firms’ renewal in face of environmental change. This study contributes to the innovation management literature, and the use of the innovation ambidexterity framework examines how firms explore new ways of creating and capturing value and face challenges.     

Co-movement in Stock Prices in Emerging Economies: The Case of the Caricom Region

The Grand Anse Declaration of 1989 recognised the need for financial integration within the emerging economies that comprise the CARICOM region, as a way of furthering the wider process of economic integration and, indeed, economic development in that region. Using co-movement as a measure of financial integration, this paper investigates the co-movement in stock prices among the Barbados, the Jamaica and the Trinidad and Tobago Stock Exchanges, the three major exchanges within the CARICOM region. It also examines how integrated these exchanges are with the New York Stock Exchange. The GARCH-Copula methodology and, to a lesser extent, estimated correlation coefficients, are used to attain this objective. There appears to be co-movement in stock prices and returns within the CARICOM stock markets and significant dependence structures between the returns of the three CARICOM stock markets. However, there is considerably less evidence of integration between the CARICOM markets and the New York Stock Exchange.
