alternative value elicitation formats in contingent valuation mechanism design and convergent validity abstract to date much of the theoretical work on the incentive properties of contingent valuation surveys has focused on the oft recommended single binary choice sbc referendum format this work has identified conditions under which an sbc elicitation is incentive compatible and empirical evidence lends support to the predictive power of the theory nevertheless researchers and practitioners commonly use alternative elicitation formats and defend their design choices based on efficiency and other criteria in this study we demonstrate that it is possible to identify conditions under which alternative elicitation formats are incentive compatible using as examples open ended oe and payment card pc question formats we then implement theory informed value elicitations in the context of a flood control policy for new york city we fail to reject convergent validity in mean willingness to pay when comparing the theory driven oe format with sbc but reject convergent validity between the theory driven pc and sbc formats as an informative counterfactual we find that a standard oe elicitation congruent with prior work leads to significantly lower values and a lower proportion of respondents who view the elicitation as consequential

should reference alternatives in pivot design sc surveys be treated differently analysts are increasingly making use of pivot style stated choice sc data in the estimation of choice models these datasets often contain a reference alternative whose attributes remain invariant across replications for the same respondent this paper presents evidence to suggest that respondents react differently to the attributes of these reference alternatives and those of purely hypothetical alternatives while some such evidence has been reported in the existing literature this paper goes further and details a number of different departures from a common treatment of the two types of alternatives relating both to the observed part of utility and the error term

bounded rationality climate risks and insurance is there a market for natural disasters this paper examines the role of insurances to reduce uncertainty associated with climate change losses for individuals of special interest is the value individuals place on the reduction of increased flood risks by insurance coverage using rank dependent utility and prospect theories risk premiums are estimated under different climate change scenarios for the netherlands the study delivers two main insights first estimation results suggest that a profitable flood insurance market could be feasible second climate change has the potential to increase the profitability of offering flood insurance 2009 by the board of regents of the university of wisconsin system

will the true labor share stand up an applied survey on labor share measures labor s share of income is a key variable in economics it plays a leading role in analysis of in equality globalization technical change growth theories etc notwithstanding this broad application there are many different definitions of the labor share understanding and synthesizing those differences is the purpose of this applied survey empirical measures may vary reflecting the allocation of income components that cannot be directly ascribed to capital or labor we examine the alternative assumptions made in the literature in this regard and quantify and motivate the resulting discrepancies focusing mostly on us data we show that different measures can have very distinct properties in terms of the observed stochastic trends shares of short medium and long run variation and volatilities persistence and mean reversion properties and susceptibility to structural breaks for instance while short run properties of the surveyed labor share measures are relatively consistent across all definitions and countercyclical their medium and long run trends may diverge substantially and are procyclical to substantiate our analysis we document the implications of discrepancies in the empirical labor share definition for growth accounting analyzing the effect of technology shocks and for estimating inflation dynamics

wind insurance and mitigation in the coastal zone this paper presents the only study analyzing the decision to purchase wind coverage for individuals whose standard homeowner s policy excludes wind and one of very few analyses of the decision to undertake wind mitigation measures because these two decisions are closely related a simultaneous mixed process approach is used that allows for correlated disturbances across probit insurance and tobit mitigation equations results indicate a positive correlation between errors of the insurance and mitigation models conditioning on covariates households that hold wind insurance tend to engage in greater levels of wind mitigation

preference reversals and the independence axiom of all of the paradoxical patterns of behavior reported in laboratory experiments one of the most perplexing for decision theorists is the preference reversal phenomenon a subject in a preference reversal experiment is typically given a choice between a lottery with a high probability of winning a modest amount of money a p bet and a lottery with a low probability of winning a large amount of money a bet the lowest amount of money for which the subject would willingly sell either of these lotteries is also elicited the most common reversal is for a subject to choose the p bet over the bet but to put a higher selling price on the bet preference reversals were first reported by harold lindman 1971 and sarah lichtenstein and paul slovic 1971 in discussing the psychologists discovery of such reversals david grether and charles plott remark the inconsistency is deeper than mere lack of transitivity or even stochastic transitivity it suggests that no optimization principles of any sort lie behind even the simplest of human choices 1979 p 623 this paper offers a simple alternative explanation of documented preference reversals an explanation that does not require the abandonment of the transitivity assumption

foreign aid an instrument for fighting communism abstract in this paper we test the argument that the sizeable reduction in aggregate aid levels in the 1990s was due to the end of the cold war we test two different models using a dynamic econometric specification on a panel of 17 donor countries spanning the years 1970 97 we find aid to be positively related to military expenditures in the former eastern bloc during the cold war but not in the 1990s suggesting that the reductions in aid disbursements are driven by the disappearance of an important motive for aid we also study the effect on aid allocation but here we do not find any robust effects of the end of the cold war

empirical evidence on inflation expectations in the new keynesian phillips curve abstract we review the main identification strategies and empirical evidence on the role of expectations in the new keynesian phillips curve paying particular attention to the issue of weak identi

elusive persistence wage and price rigidities the new keynesian phillips curve and inflation dynamics abstract we review the main new keynesian inflation equations that have arisen as a result of aggregation from individual firms price rigidities we find that on the whole they cannot account for inflation persistence a key feature of the empirical dynamics of inflation and with important policy implications the only exceptions seem to be when indexation is allowed in price setting or when price stickiness is combined with wage rigidity and staggering

evaluation of the subjective probabilities of survival in the health and retirement study in the health and retirement study respondents were asked about the chances they would live to 75 or to 85 we analyze these responses to determine if they behave like probabilities of survival if their averages are close to average probabilities in the population and if they have correlations with other variables that are similar to correlations with actual mortality outcomes we find that generally they do behave like probabilities and that they do aggregate to population probabilities most remarkable however is that they covary with other variables in the same way actual outcomes vary with the variables for example respondents with higher socioeconomic status give higher probabilities of survival whereas respondents who smoke give lower probabilities we conclude that these measures of subjective probabilities have great potential use in models of intertemporal decision making under uncertainty

risk attitudes to low probability climate change risks wtp for flood insurance abstract natural disasters may increase in frequency and severity in the future as a result of climate change which is likely to have an impact on the demand for natural disaster insurance insights about individual risk beliefs and behavioural responses to changing risks are relevant for insurers as it allows them for example to estimate the demand for new insurance products that cover weather related damage this study elicits individual risk beliefs and the demand for low probability high impact flood insurance using the contingent valuation survey method among approximately 1000 homeowners in the dutch river delta this study is of practical relevance since currently flood insurance is not available in the netherlands while insurers have been considering to provide such insurance individuals generally do not behave in accordance with the expected utility model since a significant proportion of homeowners neglect the low probability flood risk the willingness to pay wtp of those individuals who demand flood insurance is on average considerably higher than the expected value of the flood risk they face moreover the wtp for flood insurance is less than proportionally related to increased flood probabilities that were presented to respondents in the questionnaire individuals follow a process of bayesian updating of flood probabilities since perceptions of flood risk are an important determinant of the wtp while objective risks derived from geographical characteristics influence the wtp to a lesser extent communication of baseline probabilities and changes in flood probabilities using risk ladders facilitate the comprehension of risk by respondents and has a considerable effect on the level of the wtp and its sensitivity to probability changes the results indicate that the current ex post public compensation scheme of flood damage lowers demand for private insurance

optimal design for multinomial choice experiments abstract the author derives d optimal designs for main effects multinomial choice experiments using attribute levels as design parameters the design solutions are similar to standard main effects designs except that one attribute is used to manipulate response probabilities the manipulator is key to implementing optimal designs in practice

uncertainty of governmental relief and the crowding out of flood insurance this paper discusses the problem of crowding out of insurance by co existing governmental relief programs the so called charity hazard in the context of different institutional schemes of governmental disaster relief in austria and germany we test empirically whether an assured partial relief scheme as in austria drives a stronger crowding out of private insurance than a scheme promising full relief which is subject to ad hoc political decision making as in germany our general finding is that the institutional design of governmental relief programs significantly affects the demand for private natural hazard insurance

the macroeconomy of angola breaks and persistence in angolan macro data using long range dependence techniques we examine the order of integration of angola s macro variables from a fractional viewpoint based on a small open economy model the series examined are money reserves credit money supply lending rate exchange rates cpi gdp oil revenues and government expenditure for the period of january 2000 to december 2013 the results suggest that the variables are nonstationary with orders of integration equal to or higher than 1 suggesting nonmean reverting behaviour structural breaks reveal that the series reflect the imf intervention in angola in 2003 to control inflation policy implications are derived

consumer willingness to pay to reduce the probability of retail foodborne pathogen contamination abstract the us department of agriculture applies a cost of illness approach to value reductions in morbidity which may understate the projected benefits from proposed food safety improvements by ignoring costs such as pain suffering and worry we use a national survey with a hypothetical food choice experiment to estimate a more comprehensive measure of consumer willingness to pay for food safety improvements our approach differs from previous evaluations of food safety improvements because we 1 provide the respondent with information about the promised change in the probability of pathogen contamination in retail food packages rather than changes in the probability of becoming ill 2 elicit changes in respondents subjective probability of becoming ill and 3 elicit predicted changes in the quantity demanded for products that have enhanced food safety properties we estimate the consumer s choice between a safety enhanced and an existing product the change in subjective probability of contracting foodborne illness associated with the enhanced product and the change in demand for the enhanced product in a manner that recognizes the correlation among unobserved elements the aggregated results suggest benefit estimates that are significantly larger than previous estimates for similar improvements

entry by foreign firms in the united states under exchange rate uncertainty this paper tests the effects that real exchange rate fluctuations had on foreign direct investment into the united states during the 1980s using a sample of foreign investments in sixty one four digit sic u s wholesale industries this paper finds exchange rate volatility to be negatively correlated with the number of foreign investments that occur in these industries this negative effect is most pronounced for industries where sunk investments in physical and intangible assets are relatively high although exchange rate volatility deters investment from all countries its effect was most significant for investments by japanese companies copyright 1993 by mit press

aid supplies over time addressing heterogeneity trends and dynamics summary what determines how much foreign aid donors provide existing answers to this question point to a complex range of influences however the tasks of distinguishing between long and short run factors as well as differences between donors have not been adequately addressed taking advantage of data spanning nearly 50 years this paper uses panel cointegration techniques to consider these issues the analysis provides clear evidence for heterogeneity both between donors and over time bandwagon effects and a growing influence of security considerations in aid provision domestic macroeconomic shocks have a moderate but delayed effect on aid disbursements

reference dependence effects on wta and wtp value functions and their disparity in this study we investigate two reference dependence effects in a choice experiment the first is the effect of the well known distinction between gains and losses the second is the effect of changing the reference value on willingness to pay wtp and willingness to accept wta the latter has to our knowledge not been studied before we hypothesize that there are differences between wta and wtp and that both value functions and their disparity are affected by the absolute value of the reference point we test our hypotheses using a choice experiment with trade offs between changes in flood probabilities and costs the choice experiments elicit wtp and wta using two flood probability reference values yielding four separate value functions our findings show that a substantial wta wtp disparity exists and that this disparity increases when moving away from the reference point also both wta and wtp value functions are affected by the flood probability reference value and the wta wtp disparity increases when the flood probability reference point increases both findings suggest that welfare effects caused by changes in public good provision depend not only on the direction of change loss aversion but also the reference value moreover our results show that the latter effect is larger for losses than for gains we introduce the concept of reference point updating as a possible explanation for these findings

theory measurement and calibration of macroeconomic models abstract calibration has become a standard tool of macroeconomics this paper extends and refines the calibration methodology along several important dimensions first accounting for home production is important both in measuring calibration targets and in organizing the data in a model consistent fashion for this reason thinking about home production is important even if the model under consideration does not include home production second investment specific technological change is included because of its strong balanced growth parameter restrictions third the measurement strategy is laid out as transparently as possible so that others can easily replicate the underlying calculations the data and calculations used in this paper are available at http clevelandfed org research models rbc index cfm

do hypothetical and actual marginal willingness to pay differ in choice experiments application to the valuation of the environment abstract in this paper we test the validity of choice experiments with donations for environmental projects in particular we test whether or not there are differences in preferences between a hypothetical and an actual choice experiment our experiments indicate no differences in addition internal tests of validity indicate transitive and stable preferences in both experiments although there are some indications of possible learning effects during the experiment

macroeconomic effects of regulation and deregulation in goods and labor markets product and labor market deregulation reduce and redistribute rents leading economic players to adjust to this new distribution it typically comes with distribution and dynamic effects to study these effects we build a macroeconomic model on two central assumptions monopolistic competition in the goods market which determines the size of rents and bargaining in the labor market which determines the distribution of rents product market regulation determines entry costs and the degree of competition labor market regulation determines the bargaining power of workers we show the effects of deregulation we then use our results to discuss the political economy of deregulation and recent macroeconomic evolutions in europe

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

risk perceptions risk preference and acceptance of risky food consumers risk preferences are often overlooked in studies of consumer demand for risky food we find that risk preferences elicited through context less lottery choices are significantly related to consumers stated preferences for genetically modified gm food these results suggest risk preferences elicited in the laboratory are not artificial in the sense that they appear to be related to the same risk preferences that govern other individual decisions such as food choice consistent with theoretical expectations risk perceptions and risk preferences were found to be significant determinants of acceptance of gm food which has important implications for explaining consumer behavior

the political economy of foreign aid a model of the market for a public good what determines the type and quantity of overseas aid given by individual donor countries answers to this question in the existing literature are polarized into two groups one of them offers a theoretical treatment based on the theory of public goods which is not consistent with the available data and the other offers empirical correlations without any explanatory theory the first group for example pincus and olson and zeckhauser treats aid like defense as an international public good small countries on this approach are free riders spending relatively little themselves while deriving benefits from the expenditures of larger countries but this approach is not consistent with even a casual scrutiny of the oecd aid community in which broadly speaking the smallest countries are the most generous donors 2 the second group for example hoadley and beenstockdiscover correlations between a country s ratio of aid to gnp and certain independent variables which may be expected to influence it e g that country s gnp its dependence on foreign trade its government s position in the ideological spectrum and the state of the domestic economy 3 however these findings are not fitted into any theoretical framework so that it is difficult to work out what they really mean 4 the approach of this paper is to treat foreign aid as a public good for which there is a market albeit a highly imperfect one because the consumers donor country taxpayers are ignorant about the very nature let alone the price of the commodity they are buying on this view factors on the demand side i e taxpayers response to their country s aid program will help to determine the quantity of aid disbursed as well as factors on the supply side such as the donor government s desire to obtain strategic or trading benefits from aid this view

structural change in a multisector model of growth we study a multi sector model of growth with differences in tfp growth rates across sectors and derive sufficient conditions for the coexistence of structural change characterized by sectoral labour reallocation and constant aggregate growth path the conditions are weak restrictions on the utility and production functions commonly applied by macroeconomists we present evidence from us two digit industries that is consistent with our predictions about structural change and successfully calibrate the historical shift from agriculture to manufacturing and services we show quantitatively that reasonable deviations from our conditions do not have a big impact on the properties of the model

risk aversion and the propensities for self insurance and self protection for a risk averse individual the methods for reducing the expected financial impact of a loss include reducing the severity of any loss that occurs self insurance and reducing the probability of the occurrence of a loss self protection the literature on this topic has pointed to several anomalies whereby the use of self protection and self insurance yield quite unsimilar results for example ehrlich and becker 5 show that self insurance is always a substitute for market insurance an insurance company s indemnifying a loss whereas self protection and market insurance might be complements dionne and eeckhoudt 4 show that a more risk averse consumer would always invest more in self insurance activities but not necessarily more in self protection activities they argue 4 42 that this result is counterintuitive and provides an exception to the widely accepted result that increased risk aversion reduces risky activities ehrlich and becker 5 639 argue that the incentive to self protect is not so dependent on attitude towards risk both of the above papers seem to take for granted that self protection activities reduce the riskiness of the final wealth distribution however as we argue below this is not the case if riskiness is defined as in rothschild and stiglitz 14 even if we use the variance as our risk measure we do not always reduce risk via self protection dionne and eeckhoudt suggest that these results might not be robust enough to extend to models that incorporate random initial wealth risk and state dependent preferences we show that the model seems to be very robust we also explain why self protection is not at all an exception to the long standing result of arrow 1 whereby more risk averse individuals undertake a lower

should governments stop subsidies to private goods evidence from rural latin america abstract this paper empirically documents the effects of subsidizing private goods to the detriment of the government s supply of public goods we use a new data set from the rural sector in fifteen latin american countries over the period 1985 2001 collected using a methodology that allows us to separate government subsidies to private goods from expenditures in the provision of public goods the econometric evidence shows that the government s decision to subsidize either private or public goods has dramatic consequences for economic development reducing the share of subsidies to private goods or equivalently increasing the share of public goods in the government s budget has ceteris paribus a large and significant positive impact on rural per capita income reduces certain undesirable environmental effects associated with output expansion and contributes to poverty reduction

technology utilization and inflation what drives the new keynesian phillips curve we argue that the new keynesian phillips curve literature has failed to deliver a convincing measure of real marginal costs we start from a careful modeling of optimal price setting allowing for nonunitary factor substitution nonneutral technical change and time varying factor utilization rates this ensures the resulting real marginal cost measures match volatility reductions and level changes witnessed in many u s time series the cost measure comprises conventional countercyclical cost elements plus procyclical and covarying utilization rates although procyclical elements seem to dominate the components of real marginal cost components are becoming less cyclical over time incorporating this richer driving variable produces more plausible price stickiness estimates than otherwise and suggests a more balanced weight of backward and forward looking inflation expectations than commonly found our results challenge existing views of inflation determinants and have important implications for modeling inflation in new keynesian models

monetary valuation of insurance against flood risk under climate change climate change is projected to increase the risk of natural disasters such as floods and storms in certain regions this is likely to raise the demand for natural disaster insurance we present a stated preference survey using choice modeling with mixed logit estimation methods in order to examine the effects of climate change and the availability of government compensation on the demand for flood insurance by dutch homeowners currently no private insurance against flood damage is offered in the netherlands the results indicate that there are opportunities for the development of a flood insurance market 2012 by the economics department of the university of pennsylvania and the osaka university institute of social and economic research association

beyond balanced growth balanced growth models are commonly used in macroeconomics because they are consistent with the well known kaldor facts regarding economic growth these models however are inconsistent with one of the most striking regularities of the growth process the massive reallocation of labour from agriculture into manufacturing and services this paper presents a simple model consistent with both the kaldor facts and the dynamics of sectoral labour reallocation

bridging the gap between revealed and stated preferences in flood prone housing markets abstract this papers attempts to shed light on the gap between revealed and stated preferences methods in flood prone housing markets we quantitatively explore the market level consequences of various behavioural models assumptions regarding risky choices at the individual level in addition we quantify the effect of the market level bias in risk valuation that individual preferences for neighbourhood quality imply we apply an economic agent based housing market model to quantify and disentangle the impacts of behavioural biases in individual decisions under risk as well as neighbourhood externalities which both are known to distort markets we compare three different micro level behavioural risk models expected utility prospect theory and risk negligence the flood risk discount on a market level varies significantly but the results do not rule out any of these models in general markets with prospect theory traders overprice risks causing an unrealistically high price differential between risk prone and risk free properties the marginal implicit price for flood risk is much closer to empirically found prices in the expected utility and risk negligence models additionally we find that individual preferences for neighbourhood quality and multicollinearity in housing attributes can cause a bias in market level risk valuations of up to 9 7 of a property s value

can natural experiments measure behavioral responses to environmental risks efforts to measure people s responses to spatially delineated risks confront the potential for correlation between these risks and other unobserved characteristics of these locations the possibility of correlation arises in part because individuals observe other locational attributes that can be expected to influence the hedonic equilibrium one response to this problem is to use events from nature to exploit both temporal and spatial variation in the behavioral responses of interest this paper evaluates the use of hurricanes as a source of new risk information to households in coastal counties potentially subject to the effects of these storms we study the extent to which housing prices before and after hurricane andrew a hurricane with unprecedented property loss reveal how floridians responded to the risk information provided by the storm two counties are selected one without and another with damage from the hurricane to evaluate the plausibility of using quasi random experiments for locations not directly affected by natural events we compare lee county s results to those of dade county where the majority of the damage occurred our findings suggest after controlling for ex post storm damage and changes in insurance markets there is a reasonably high level of consistency in a repeat sales model s ability to estimate the effects of the risk information conveyed by the storm for both counties

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

aid catastrophes and the samaritan s dilemma this paper discusses the impact of foreign aid on the recipient country s preparedness against natural disasters the theoretical model shows that foreign aid can have two opposing eects on a country s level of mitigating activities in order to test the theoretical propositions we analyse the eect of foreign aid dependence on ex ante riskmanagement activity proxied by the death toll from major storms floods and earthquakes occurring worldwide between 1980 and 2002 we find evidence that the crowding out eect of foreign aid outweighs the preventive eect in the case of storms while there is mixed evidence in the case of floods and earthquakes

aid quality and donor rankings this paper offers new measures of aid quality covering 38 bilateral and multilateral donors as well as new insights about the robustness and usefulness of such measures the 2005 paris declaration on aid effectiveness and the follow up 2008 accra agenda for action have focused attention on common donor practices that reduce the development impact of aid using 18 underlying indicators that capture these practices derived from the oecd dac s survey for monitoring the paris declaration the new aiddata database and the dac aid tables the authors construct an overall aid quality index and four coherently defined sub indexes on aid selectivity alignment harmonization and specialization compared with earlier indicators used in donor rankings this indicator set is more comprehensive and representative of the range of donor practices addressed in the paris declaration improving the validity reliability and robustness of rankings one of the innovations is to increase the validity of the aid quality indicators by adjusting for recipient characteristics donor aid volumes and other factors despite these improvements in data and methodology the authors caution against overinterpretation on overall indexes such as these alternative plausible assumptions regarding weights or the inclusion of additional indicators can still produce marked shifts in the ranking of some donors so that small differences in overall rankings are not meaningful moreover because the performance of some donors varies considerably across the four sub indexes these sub indexes may be more useful than the overall index in identifying donors relative strengths and weaknesses

does federal disaster assistance crowd out flood insurance abstract we empirically analyze whether federal disaster aid crowds out household purchase of disaster insurance we combine data on annual household flood insurance purchases for the united states over the period 2000 2011 with data from the two main u s post disaster federal aid programs fema s individual assistance grants and sba s low interest disaster loans estimating both fixed effects and instrumental variable models to account for the endogeneity of disaster assistance grants we find that receiving individual assistance grants decreases the average quantity of insurance purchased the following year by between 4000 and 5000 the reduction we find is roughly 3 of the mean insurance coverage in the sample but larger than the average flood related ia grant in our sample which is 2984 ia is currently limited and larger grants could have different impacts the crowding out is on the intensive margin we find no impact on take up rates likely because there is a requirement that recipients of disaster aid purchase an insurance policy we do not know how take up rates might change without such a requirement low interest post disaster government loans have no systematic effect on insurance purchases

examining risk preferences under high monetary incentives experimental evidence from the people s republic of china several experimental sessions were conducted to elicit certainty equivalents for a sequence of lotteries involving real monetary outcomes the opportunity to conduct sessions in the people s republic of china afforded the ability to offer very large monetary incentives relative to subjects living costs in the highest payoff condition subjects earned three times their normal monthly revenue in the course of a two hour experiment results indicate a statistically significant impact of the level of monetary incentives on revealed risk preferences however even under extreme monetary incentives subjects demanded amounts well in excess of expected value for low probability gain prospects copyright 1992 by american economic association

valuing low probability risk survey and experimental evidence abstract this study uses a survey question and an economics experiment to elicit the value of a risk mitigation investment for 93 subjects 48 males and 45 females the responses to hypothetical questions are compared with a risk mitigation decision that has a salient outcome we find no gender differentiated responses to either the maximum accepted price in the economics experiment or hypothetical willingness to pay questions from the survey in our design the two procedures generate aggregate measures that were in close agreement however individual decisions were seldom consistent

estimating risk preferences from deductible choice we develop a structural econometric model to estimate risk preferences from data on deductible choices in auto insurance contracts we account for adverse selection by modeling unobserved heterogeneity in both risk claim rate and risk aversion we find large and skewed heterogeneity in risk attitudes in addition women are more risk averse than men risk aversion exhibits a u shape with respect to age and proxies for income and wealth are positively associated with absolute risk aversion finally unobserved heterogeneity in risk aversion is greater than that of risk and as we illustrate has important implications for insurance pricing

new phillips curve under alternative production technologies for canada the united states and the euro area abstract this paper shows that alternative production technologies imply two modifications to the new phillips curve npc a specific strategic complementarity parameter that affects the relationship between real marginal cost and inflation and a specific modification to the labour share measure of real marginal cost estimates of average duration of nominal price stickiness obtained conditional on the strategic complementarity parameter are substantially smaller and therefore more plausible relative to when this parameter is ignored modifications to the marginal cost measure alone have little effect on the npc estimates the empirical fit of the npc under alternative production technologies is similar
