norms and contracting we argue that contracts establish the norms of a relationship and that individuals incur disutility when deviating from these norms in a laboratory experiment we allow agents to make simple contracts before they play one of four games and the most effective contract always includes an unenforceable handshake agreement to take the first best action in three games a contract with only this handshake agreement is at least weakly optimal the handshake is particularly effective in games with strategic complements our results highlight an explanation for contractual incompleteness establishing a norm can effectively substitute for weak enforceable restrictions this paper was accepted by brad barber teck ho and terrance odean special issue editors

renewable energy as a luxury a qualitative comparative analysis of the role of the economy in the eu s renewable energy transitions during the double crisis the european union eu faces a double crisis both economic and environmental which has brought into stark relief the question of whether climate change mitigation and economic growth are mutually exclusive is saving the environment a luxury reserved for wealthy countries with less affluent countries being too poor to be green we seek to address this important and timely question using fuzzy set qualitative comparative analysis fsqca to analyse the causal relationship between economic growth and stability and the expansion of renewable electricity shares among the european union s eu 28 member states during the recent economic recession 2008 2013 our paper analyses the recent economic and financial crisis and its effects on sustainability transitions and establishes a new indicator for progress in renewable electricity transitions in the context of europe s 2020 targets it therefore extends the sustainability as a luxury debate to include renewable energy the analysis reveals an ambivalent picture of the role of wealth in renewable energy transitions ret in europe indeed driven by the eu s common renewable energy targets the findings suggest that rets are promoted both because and in spite of the means

evaluating the evidence on union employment and wages using current population survey data for the years 1973 86 this study tests the hypothesis that the steep decline of union employment shares since 1973 is related to increases in union wages relative to nonunion wages the authors show that although the aggregate union wage premium has changed little since 1973 some industry specific premiums have risen substantially and the industries with the rising premiums are those experiencing declines in union employment shares the increase in the premium explains from 21 to 64 of the decline in union shares depending on the equation specification the paper also presents a detailed set of union wage premiums and employment shares for the sample period

revealed preference and household production abstract the paper deals with the possibilities of recovering the underlying preference ordering from observed behavior when nonmarket goods are employed in household production the problem is relevant for the evaluation of environmental goods and for the measurement of welfare in environmental policy it is shown that preferences can be recovered if and only if a corresponding mixed demand system can be integrated this system can be derived from observable behavior and the household production functions imposed the conditions for its integrability are presented and can be checked therefore the approach suggested is operational and allows to decide whether the behavior observed and the household production functions chosen as maintained hypothesis are consistent this result is important since the evaluation of nonmarket goods in this framework crucially depends on the choice of the household production functions

can proximity to urban green spaces be considered a luxury classifying a non tradable good with the use of hedonic pricing method abstract environmental goods are sometimes considered a luxury that only the rich can afford this is no less true in the case of green spaces however a typical microeconomic lens is not relevant to study the potential luxury of non tradable goods typically the distributional interpretation of the income elasticity of the willingness to pay wtp for such goods would involve stated preferences valuation methods the possibility to describe the luxury of green space proximity based on revealed preferences methods has not been evaluated yet through this study we would like to fill this gap we proposed a three step analysis of the apartment market in lodz poland based on the hedonic pricing method to check how the marginal wtp mwtp for proximity to parks forests differs among apartment price sub segments we discuss whether and to what extent the variability of the mwtp could be linked with the presumed luxury of green space proximity we found that proximity does not result in increased apartment prices for all parks and forests the estimated mwtp for the proximity to selected parks rises in consecutive apartment price sub segments this could be interpreted as a sign of the luxury of living close to these parks by apartment buyers

a meeting of the minds informal agreements and social norms using coordination games we elicit social norms directly for two different games where either an agreement to take the first best action has been reached or where no such agreement exists we combine the norms data with separately measured choice data to predict changes in behavior we demonstrate that including social norms as a utility component significantly improves predictive performance then we compare social norms to guilt aversion and lying aversion we estimate that honoring an agreement in the double dictator game is worth giving up approximately 10 of total earnings and more than 120 in the bertrand game we show that informal agreements affect behavior through their direct effect on social norms as well as through an indirect effect on beliefs this paper was accepted by uri gneezy behavioral economics

integrating non monetary and monetary valuation methods softgis and hedonic pricing abstract in order to address the increasing need for improved linkages between different value perspectives we examine the possibility of integrating two valuation methods the non monetary softgis and monetary hedonic pricing we find them compatible and their output more comprehensive compared to traditional valuation based on one value perspective the public participatory softgis survey delivers information on the perception of urban green spaces which we use as a criterion for dividing green space categories in a hedonic pricing model we find that the perception expressed in the survey is generally consistent with the impact on property prices in the case of formal green spaces however it is inconsistent when it comes to informal ones places identified as lacking well maintained greenery exert a positive influence on property prices while positively evaluated informal green spaces had no impact at all we identify the latter as a typical trade off between different value perspectives informal green spaces are perceived differently following a monetary and a non monetary approach

land and power theory and evidence from chile many employment relationships concede rents to workers depending on the political institutions the presence of such rents allows employers to use the threat of withdrawing them to control their workers political behavior such as their votes in the absence of secret ballot we examine the effects of the introduction of the secret ballot in chile in 1958 on voting behavior before the reforms localities with more pervasive patron client relationships tended to exhibit a much stronger support for the right wing parties traditionally associ ated with the landed oligarchy after the reform however this difference across localities completely disappeared jel d72 n46 o13 o15 o17

is the income elasticity of environmental improvements less than one we estimated the income elasticity of environmental improvements for a number of european data sets the value of this parameter is consistently found to be less than one with few exceptions our findings are compared with state of the art contingent valuation studies from other countries we also compared our findings with those reported in the literature on charitable donations and corporate donations these studies show a similar pattern donations decrease as a percentage of income as income increases

exposing corrupt politicians the effects of brazil s publicly released audits on electoral outcomes author s finan frederico ferraz claudio abstract this paper examines the extent to which access to information enhances political accountability based upon the results of brazil s recent anti corruption program that randomly audits municipal expenditures of federally transferred funds it estimates the effect of the disclosure of local government corruption practices upon the re election success of incumbent mayors in municipal elections comparing municipalities which were randomly audited before the elections with those audited after the analysis shows that the disclosure of audit results had a significant impact on the re election rates of mayors found to be corrupt for a one standard deviation increase in reported corruption the audit policy reduced the incumbent s likelihood of re election by 25 percent this effect is more pronounced in municipalities where radio stations are present and higher levels of corruption are identified these findings highlight the value of information and the role of the media in reducing informational asymmetries in the political process thus enabling voters to not only hold corrupt politicians accountable but also to reward non corrupt politicians

a dual self model of impulse control we propose that a simple dual self model gives a unified explanation for several empirical regularities including the apparent time inconsistency that has motivated models of quasi hyperbolic discounting and rabin s paradox of risk aversion in the large and small the model also implies that self control costs imply excess delay as in the o donoghue and rabin models of quasi hyperbolic utility and it explains experimental evidence that increased cognitive load makes temptations harder to resist the base version of our model is consistent with the gul pesendorfer axioms but we argue that these axioms must be relaxed to account for the effect of cognitive load

temptation in vote selling evidence from a field experiment in the philippines abstract we report the results of a randomized field experiment in the philippines on the effects of two common anti vote selling strategies involving eliciting promises from voters an invitation to promise not to vote sell is taken up by most respondents reduces vote selling and has a larger effect in races with smaller vote buying payments the treatment reduces vote selling in the smallest stakes election by 10 9 percentage points inviting voters to promise to vote your conscience despite accepting money is significantly less effective the results are consistent with a behavioral model in which voters are only partially sophisticated about their vote selling temptation

measuring vote selling field evidence from the philippines abstract using data from an anti vote buying field experiment we conducted in the philippines we report and validate a proxy measure for vote selling we demonstrate that our proxy measure vote switching changes as expected with voter preferences and monetary offers from candidates voters are less likely to vote for someone different than their initial preference the larger the favorability rating difference between the preferred and alternative candidates similarly vote switching increases the more money the alternative candidate offers compared to the preferred candidates we also describe the effects of the promise based interventions on vote switching reported in full in a companion paper

promises and conventions an approach to pre play agreements abstract i analyze how informal agreements can be sustained by moral emotions with regard to a large class of two player games specifically i assume that people feel guilty if they breach an agreement and that the guilt increases according to the degree of the harm inflicted on the other a central insight is that it is easier to sustain efficient informal agreements if actions are strategic complements than if they are strategic substitutes i complement this general insight by studying two specific cases where negotiators face uncertainty about the breach of the agreement i show that while the optimal agreement in a game with strategic substitutes must compromise on surplus maximization and efficiency the optimal agreement in a game with sufficiently strong strategic complements tends to maximize both the surplus and the probability of compliance especially if the game is symmetric

value for money vote buying and politician accountability abstract the prevalence of vote buying is widely identified as a cause of poor governance in the developing world potential mechanisms for this relationship include the selection of lower quality politicians and the reduced accountability experienced by politicians once elected in this paper we present the first experimental evidence in support of the second channel of reduced accountability using data from laboratory experiments conducted in the u s and kenya we find that vote payments reduce voters willingness to hold politicians accountable holding fixed politician identity voters who receive payments are less willing to punish the politician for rent seeking and this reduction in punishment is larger in magnitude when payments are widely targeted unsurprisingly the politician then engages in a higher level of rent seeking a simple model of multi faceted social preferences encompassing reciprocity and inequality aversion is consistent with these findings

why do people keep their promises an experimental test of two explanations numerous psychological and economic experiments have shown that the exchange of promises greatly enhances cooperative behavior in experimental games this paper seeks to test two theories to explain this effect the first posits that individuals have a preference for keeping their word the second assumes that people dislike letting down others payoff expectations according to the latter account promises affect behavior only indirectly because they lead to changes in the payoff expectations attributed to others i conduct an experiment designed to distinguish between and test these alternative explanations the results demonstrate that the effects of promises cannot be accounted for by changes in payoff expectations this suggests that people have a preference for promise keeping per se

the difficult transition from clientelism to citizenship lessons from mexico author s fox jonathan a abstract electoral competition is necessary but not sufficient for the consolidation of democratic regimes not all elections are free and fair nor do they necessarily lead to actual civilian rule or respect for human rights if there is more to democracy than elections then there is more to democratization than the transition to elections but in spite of the rich literature on the emergence of electoral competition the dynamics of political transitions toward respect for other fundamental democratic rights is still not well understood political democracy is defined here in classic procedural terms free and fair electoral contestation for governing offices based on universal suffrage guaranteed freedoms of association and expression accountability through the rule of law and civilian control of the military although analyses of democratization typically acknowledge that these are all necessary criteria most examine only electoral competition this study however develops a framework for explaining progress toward another necessary condition for democratization respect for associational autonomy which allows citizens to organize in defense of their own interests and identities without fear of external intervention or punishment

environmental goods and the distribution of income the paper presents a theoretical investigation of the distributional impacts of environmental commodities it introduces an appropriate framework defines concepts for measuring benefits and examines the determinants of benefit incidence within this setup its emphasis is on methodology and on recognizing the relevant economic variables and information it turns out that in an equal preference model the magnitude of the income elasticity of marginal willingness to pay for an environmental good is the crucial variable determining progressivity it is related to a number of other elasticities which are more easily accessible to an empirical estimation

nudging farmers to use fertilizer theory and experimental evidence from kenya we model farmers as facing small fixed costs of purchasing fertil izer and assume some are stochastically present biased and not fully sophisticated about this bias such farmers may procrastinate post poning fertilizer purchases until later periods when they may be too impatient to purchase fertilizer consistent with the model many farmers in western kenya fail to take advantage of apparently profit able fertilizer investments but they do invest in response to small time limited discounts on the cost of acquiring fertilizer free deliv ery just after harvest calibration suggests that this policy can yield higher welfare than either laissez faire policies or heavy subsidies

contingent valuation and social choice the contingent valuation method for estimating the existence value of natural resources is examined for psychophysical robustness statistical reliability and economic sensibility extensions of standard models for willingness to pay and suitable econometric techniques for analyzing these models are developed the analysis is applied to a series of experiments on the value of preserving wilderness areas in the western united states the results call into question the reliability of the cv method for estimating existence values

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

demand for environmental quality an empirical analysis of consumer behavior in sweden in this paper we estimate the income elasticity of demand for recreational services and other traditional groups of goods in sweden and test for potential changes in such estimates over the twentieth century due to the difficulty of directly observing the demand for recreational services we employ an indirect methodology by using the demand for some outdoor goods as a proxy for the demand for recreational services in line with most prior research our results confirm the expectation that recreational services as a public good is a luxury good in sweden our results also show that the income elasticities for traditional goods are stable over time indicating that consumer preferences for expenditure on these specific commodities do not change over time

clientelism and voting behavior evidence from a field experiment in benin the author conducted a field experiment in benin to investigate the impact of clientelism on voting behavior in collaboration with four political parties involved in the 2001 presidential elections clientelist and broad public policy platforms were designed and run in twenty randomly selected villages of an average of 756 registered voters using the survey data collected after the elections the author estimated the effect of each type of message by comparing voting behavior in the villages exposed to clientelism or public policy messages treatment groups with voting behavior in the other villages control groups the author found that clientelist messages have positive and significant effect in all regions and for all types of candidates the author also found that public policy messages have a positive and significant effect in the south but a negative and significant effect in the north in addition public policy messages seem to hurt incumbents as well as regional candidates finally the evidence indicates that female voters tend to have stronger preference for public policy platforms than male voters

planning for green infrastructure the spatial effects of parks forests and fields on helsinki s apartment prices abstract as the importance of urban green spaces is increasingly recognised so does the need for their systematic placement in a broader array of socioeconomic objectives from an urban planning and economics perspective this represents a spatial task if more land is allocated to various types of green how do the economic effects propagate throughout urban space this paper focuses on the spatial marginal effects of forests parks and fields and estimates spatial hedonic models on a sample of apartment transactions in helsinki finland the results indicate that the capitalization of urban green in apartment prices depends on the type of green but also interacts with distance to the city centre additionally the effects contain variable pure and spatial spillover impacts also conditional on type and location the separation of which highlights aspects not commonly accounted for the planning of green infrastructure will therefore benefit from parameterizing interventions according to location green type and character of spatial impacts

the personal vote and the efficacy of education spending in this article we explore the ways in which incentives to cultivate a personal vote affect the efficiency of education spending in developing democracies we argue that where the electoral system provides incentives for political particularism resources are allocated less efficiently and the effect of increased spending on literacy is diminished we test our hypotheses using data on education spending and performance in over 40 developing democracies since 1980 we find that though personal vote systems spend just as much on education as party vote systems particularism in personal vote systems dampens the marginal effect of increased education spending on illiteracy and at its highest levels incentives to cultivate a personal vote completely undermine the positive effects of increased education spending on literacy

the relationship between the income elasticities of demand and willingness to pay abstract the relationship between income and willingness to pay for collectively provided public environmental goods is investigated we show that while the income elasticity of willingness to pay and the ordinary income elasticity of demand are related knowledge of one is insufficient to determine the magnitude or even the sign of the other the income elasticity of willingness to pay is influenced by additional factors which are generally unobservable examples are provided to illustrate the degree to which the two income elasticities may diverge our results indicate that even when goods are demand luxuries they may or may not have income elasticities of willingness to pay which are greater than one
