Provided and perceived status quo in choice experiments: Implications for valuing the outputs of multifunctional rural areas

This article presents a choice experiment analyzing multifunctional rural development policies targeting conservation and recovery of environmental, social and cultural assets. In choice experiments a base alternative is usually included in order to estimate the welfare change associated to policy proposals. This study is concerned with the much neglected issue of the impact on policy analysis of the definition of a ‘status quo’ alternative either as an objective assessment by experts, or as a self-reported perception by respondents. Convergent validity analysis and prospective policy scenarios show a significant impact of different status quo specifications on individuals' preferences and related welfare measures when complex and unfamiliar biophysical systems are involved in policy analysis and evaluation.     

Holding back from theory: limits and methodological alternatives of randomized field experiments in development economics

ABSTRACT

In this paper, we critically and constructively examine the methodology of evidence-based development economics, which deploys randomized field experiments (RFEs) as its main tool. We describe the context in which this movement started, and illustrate in detail how RFEs are designed and implemented in practice, drawing on a series of experiments by Pascaline Dupas and her colleagues on the use of bednets, saving and governance in Kenya. We show that this line of experiments have evolved to address the limitation of obtaining policy-relevant insights from RFEs alone, characterized as their lack of external validity in the literature. After examining the two prominent responses by leading figures of evidence-based development economics, namely machine learning and structured speculation, we propose an alternative methodological strategy that incorporates two sub-fields, namely experimental economics and behavioral economics, to complement RFEs in investigating the data-generating process underlying the treatment effects of RFEs. This strategy highlights promising methodological developments in RFEs neither captured by the two proposals nor recognized by methodologists, and also guides how to combine different sub-fields of economics.     

Political economy and the closet: heteronormativity in feminist economics

Abstract

Returning to a question raised by M. V. Lee Badgett in the first issue of Feminist Economics, this paper traces the persistence of heteronormativity in feminist economics to assumptions that kinship is organized around conjugal bonds. These assumptions let “the family” stand automatically for a husband, wife, and their children. “Heteronormativity” is not a synonym for heterosexual privilege, but rather names tacit conceptions about what is socially normal, conceptions that make it possible to think of heterosexuals or homosexuals as essential categories of people. Critique of heteronormativity makes visible a pattern of state repression that makes proper citizens by opposing them to improper ones, a process that simultaneously shapes gender, sexuality, citizenship, and race. Such critique opens the opportunity to better understand gender, integrate scholarship on lesbians and gays, link gender analysis more directly to racializing processes, and reopen the category of heterosexuality.     

Optimal compliance with emission constraints: dynamic characteristics and the choice of technique

The paper analyzes how to comply with an emission constraint, which restricts the use of an established energy technique, given the two options to save energy and to invest in two alternative energy techniques. These techniques differ in their deterioration rates and the investment lags of the corresponding capital stocks. Thus, the paper takes a medium-term perspective on climate change mitigation, where the time horizon is too short for technological change to occur, but long enough for capital stocks to accumulate and deteriorate. It is shown that, in general, only one of the two alternative techniques prevails in the stationary state, although, both techniques might be utilized during the transition phase. Hence, while in a static economy only one technique is efficient, this is not necessarily true in a dynamic economy.      

Quasi-linear preferences in the macroeconomy: Indeterminacy,heterogeneity and the representative consumer

We use aggregation theory to investigate the link between one-consumer and multi-consumer economies under a quasi-linear class of preferences. Our study is carried out in the context of the neoclassical growth model. The quasi-linear preferences considered are additive in consumption and leisure and linear in leisure. We first show that in a homogeneous agents economy, the individual hours worked are not uniquely determined. We then demonstrate that the indeterminacy can be resolved by introducing heterogeneity. For example, idiosyncratic shocks to productivities or imperfect substitutability of labor restore the uniqueness of equilibrium. As a special case, our analysis includes the indivisible labor model by Hansen (1985).JEL Classification: C73, D90, E21We are grateful to Morten Ravn for his guidance.

Reforming the local public sector: economics and politics in privatization of water and solid waste

Several empirical studies have analyzed the factors that influence local privatization. We examine the influence of transaction costs and political factors on local governments’ choices through new variables. We consider two relevant services accounting for different amounts of transaction costs: water and solid waste delivery. Our results show that privatization is less common for water, which has higher transaction costs. Furthermore, we find that municipalities with a conservative ruling party privatize more often regardless of the ideological orientation of the constituency. Finally, we find that intermunicipal cooperation may be a suitable organizational form for some municipalities.     

Social Preferences in the Lab: A Comparison of Students and a Representative Population

We report from a lab experiment conducted with a sample of participants that is nationally representative for the adult population in Norway and two student samples (economics students and non‐economics students). The participants make choices both in a dictator game (a non‐strategic environment) and in a generalized trust game (a strategic environment). We find that the representative sample differs fundamentally from the student samples, both in the relative importance assigned to different moral motives (efficiency, equity, and reciprocity) and in the level of selfish behavior. It is also interesting to note that the gender effects observed in the student samples do not correspond to the gender effects observed in representative sample. Finally, whereas economics students behave less pro‐socially than non‐economics students, the two student groups are similar in the relative importance they assign to different moral motives.     

Incorporating research findings in the economics syllabus: evidence on genuine sociality from Italy and the UK

Economics education is proving slow in incorporating into the syllabus the genuine advances made in economics research in the last few decades. As economics education relies primarily on the single approach of neoclassical economics, whilst recent advances in research have been marked by a wide variety of approaches, many of which are interdisciplinary, the methodological divide between education and research is growing wider. We attempt to measure how keen students are to incorporate research findings in the syllabus by developing a questionnaire which introduces undergraduate students in Italy and the U.K. to key findings in the research literature on genuine sociality, an area in which the methodological divide is very noticeable. Students display moderate support for being taught the material on genuine sociality. Students who wish to incorporate genuine sociality in the syllabus tend to be older, value virtue and have a religion.     

Writing in the discipline and reproducible methods: A process-oriented approach to teaching empirical undergraduate economics research

The authors of this article describe an empirical research project as a component of an upper-level undergraduate economics writing-in-the-discipline course, thus aiming to reduce the high fixed costs associated with designing an empirical research project assignment and encourage more undergraduate economics research. This project is central to the course structure and has a dual-purpose: to teach students economics writing conventions and reproducible empirical research methods. The authors present a sequenced project design and replication documentation protocol and posit that this promotes student learning and leads to improvements in organization and coherence throughout the entire research and writing process. As an essential element of the course, students learn to do econometrics through effective writing, data management, and empirical analysis.     

Shaping beliefs in experimental markets for expert services: Guilt aversion and the impact of promises and money-burning options

In a credence goods game with an expert and a consumer, we study experimentally the impact of two devices that are predicted to induce consumer-friendly behavior if the expert has a propensity to feel guilty when he believes that he violates the consumerʼs payoff expectations: (i) an opportunity for the expert to make a non-binding promise; and (ii) an opportunity for the consumer to burn money. In belief-based guilt aversion theory the first opportunity shapes an expertʼs behavior if an appropriate promise is made and if it is expected to be believed by the consumer; by contrast, the second opportunity might change behavior even though this option is never used along the predicted path. Experimental results confirm the behavioral relevance of (i) but fail to confirm (ii).     

Direct democracy in Australia: Voter behavior in the choice between constitutional monarchy and a republic

Opinion polls conducted throughout the 1990s indicate most Australians favor a republic. A referendum making that constitutional change, however, was defeated. This paper investigates whether voters employ a loss-minimization rule, as opposed to a value-maximization rule, when making political decisions. Based on the predictions of each rule, political strategies are devised and compared to the official arguments employed by republicans and monarchists during the period preceding the vote. Empirical research relates voting outcomes at the individual voter level to influences that are likely to be correlated with political risk aversion. The results are consistent with the conclusion that voters do not employ value-maximization rules.     

New Powers and the Distribution of Preferences in Global Trade Governance: From Deadlock and Drift to Fragmentation

ABSTRACT

Existing theories make divergent predictions about the impact of new powers on the global political economy. Some argue that a more even distribution of power will erode international cooperation, while others argue that cooperation can continue with the help of international institutions to overcome collective action problems. We argue that this debate overlooks a critical determinant of the shape of power transitions: the distribution of preferences amongst the major powers. It is primarily in the context of divergent preferences that power transitions are likely to give rise to conflict. Moreover, even where preferences diverge, the gains of cooperation provide a strong incentive to continue to pursue goals through multilateralism. This situation leads to forms of institutional change unanticipated by established theories. These include deadlock in expansive multilateral fora, institutional drift as old rules cannot keep up with the changing political and economic context, and fragmentation as countries seek minilateral solutions that reduce preference diversity. We develop this preference-based, institutional argument by examining the distribution of preferences and institutional change at the World Trade Organization (WTO) and its Doha Round, where the power transition is relatively advanced.     

Productivity and environmental regulation: the effect of the nitrates directive in the French pig sector

This paper measures the ensuing changes in productivity in the French pig sector following the introduction of the European regulation addressing water pollution by nitrates from agriculture. Productivity is measured using the Malmquist–Luenberger index. The sources of changes in productivity observed are examined by breaking down this index into its technical progress and efficiency components. The results show that in the early stages, increases in productivity were stimulated by increased efficiency, before being driven by technical progress. The estimations regarding the sources of efficiency gains for the farms in the sample (technical efficiency, efficiency of scale and environmental efficiency) are then used to estimate the indirect costs and benefits (or negative costs) linked to the introduction of the environmental regulation controlling the disposal of organic manure and the management of nitrogen surplus from pig farms. The existence of a “win-win” effect as regards the Porter hypothesis relation between efficiency and environmental regulation is highlighted for the French pig sector.      

Tariffs and non-tariff barriers to trade in Hungary: The impact of the Uruguay Round and EU accession

International trade has featured prominently in Hungary's rapid transition to a market economy. This paper reports some relatively simple summary and complementary indicators for tariffs and non-tariff barriers (NTBs) to trade, which are designed to reflect the level and structure of tariffs and the scope of NTBs in Hungary. The existence of tariff 'spikes' and highly pervasive NTBs in certain sectors constitutes prima facie evidence that the domestic dead-weight efficiency and net welfare losses caused by tariff and non-tariff protection as well as the costs to consumers could be high. The indicators are used to highlight several key developments associated with Hungary's transition to a market economy, implementation of the Uruguay Round (UR) agreements and possible accession to the EU.     

Asymmetric search and prospect theory: choice experiment on consumer willingness to search in the gasoline retail market

We use an internet survey conducted among a representative random sample of drivers in the State of Ohio consisting of a choice experiment designed to examine the mechanism driving asymmetric search. The internet survey affords us the opportunity to overcome endogeneity difficulties by imposing exogenous price changes on gasoline consumers to examine the decision-making process behind intended search decisions. We randomly assigned participants to one of five price treatments (either 2.5 or 5% above or below their reported expected price, or no change). We provide a simple empirical model to derive testable implications under prospect theory and use the internet survey to test them. Results indicate that among the respondents who faced prices below their expected price, only 12% chose to search, whereas 45% searched when prices were above. Further, we find results consistent with asymmetric search being driven by prospect theory. The change in consumers’ willingness to search is twice as large when prices exceed expectations by 2.5% relative to when prices exceed them by 5% suggesting that consumers derive utility of finding a good deal evaluated relative to a reference price. We show that this result is inconsistent with standard utility theory or consumers using alternative reference prices.     

Game,set and match: the favourite-long shot bias in tennis betting exchanges

We test for the existence of Favourite-Longshot Bias (FLB) in tennis betting exchanges. Despite these being order-driven markets, with no direct participation from bookmakers, we have found very similar results to those obtained by Lahvi?ka (2014) for bookmakers’ betting markets: the bias is stronger in matches between lower-ranked players, in later round matches and in high profile tournaments. This suggests that bookmakers’ adjustments to respond to informed betting are not the main driver of FLB. The varying magnitude of the bias across different types of event in the main market also weakens arguments linking FLB to gamblers’ risk preferences, and suggests the need to consider the microstructure features of the market together with the cognitive biases highlighted in the behavioural finance literature.     

On the importance of institutions and forms of organisation in Piero Sraffa's economics: the case of business cycles,money, and economic policy

Abstract

This paper is based on an investigation of the Sraffa Archives and tries to characterise Piero Sraffa's approach to business cycles and economic policy. It includes two parts. The first part of the paper shows the importance of economic institutions and social conventions in Sraffa's contribution to economics and their relation with social conflicts. The second part of the paper shows how this importance permits to understand better business cycles and economic policy but also indirectly contributes to a re-interpretation of Sraffa's contribution to economics.

Relating the philosophy and practice of ecological economics: The role of concepts, models, and case studies in inter- and transdisciplinary sustainability research

We develop a general and unifying methodology for ecological economics which integrates philosophical considerations on the foundations of ecological economics with an adequate operationalization. We argue that the subject matter and aims of ecological economics require a specific combination of inter- and transdisciplinary research, and discuss the epistemological position on which this methodology is based. In accordance with this understanding of inter- and transdisciplinarity and the underlying epistemological position, we develop an operationalization which comprises simultaneous analysis on three levels of abstraction: concepts, (generic) models and case studies. This provides a systematic and integral view on ecological economics, and thus allows one to see the relationship between contributions to the field that have so far been perceived as very heterogeneous and largely unrelated. At the same time, this methodological framework may provide orientation for the further development of ecological economics.     

如何实现经济增长的效率和公平双目标?——基于联立方程模型的研究
