a test of independence of discounting from quality of life the quality adjusted life years qaly model assumes quality and quantity of life can be multiplied into a single index and requires quality and quantity to be mutually independent which need not hold empirically this paper proposes a new test for measuring independence of utility of life duration from quality of life in a riskless setting we use a large representative sample of dutch citizens and include two health states generally considered better than dead btd and one health state considered worse than dead wtd independence cannot be rejected when comparing the btd health states but is rejected when comparing the btd states with the wtd state in particular utility of life duration becomes more concave for the wtd state this may suggest that independence holds only for btd health states this has implications for the qaly model and would require using sign dependent utility of life duration functions

financial development income inequality and the redistributive effects of monetary policy abstract how should financial systems be designed to limit income inequality does the redistributive impact of inflation depend on the extent of financial development should optimal monetary policy vary across countries with different levels of financial development in order to address these questions we develop a monetary growth production model with heterogeneous agents in our economy optimal policy needs to weigh the effects of policy across two groups capital owners and individuals who hold liquid assets in this environment we compare various economies that are identical in every aspect except for their level of financial development interestingly we generally find that economies at the highest stages of financial development economies in which money bonds and claims to capital are traded experience the highest amount of capital formation and social welfare as long as inflation is low yet regardless of the extent of financial development there are generally redistributive consequences from inflation moreover the model tends to predict that economies with relatively small stock markets produce the highest levels of income inequality empirical work examining the role of money growth and the implications of financial development across countries is consistent with predictions from the model

a consistency test of the time trade off this paper tests the internal consistency of time trade off utilities we find significant violations of consistency in the direction predicted by loss aversion the violations disappear for higher gauge durations we show that loss aversion can also explain that for short gauge durations time trade off utilities exceed standard gamble utilities our results suggest that time trade off measurements that use relatively short gauge durations like the widely used euroqol algorithm are affected by loss aversion and lead to utilities that are too high

quota allocation of coal overcapacity reduction among provinces in china abstract laying down fair and economically viable policies to allocate quotas of coal overcapacity reduction to provinces has drawn great attention from both governments and enterprises in this study the production function method and panel variable coefficient model are used to estimate the boundary production function and coal capacities of 25 coal producing provinces the results predict that china s coal overcapacity will reach more than 0 803 billion tons by 2020 then a quota allocation model of coal overcapacity reduction among the provinces is proposed based on nonlinear programming with the aim of minimizing the total cost of national overcapacity reduction the results show that the total cost of national overcapacity reduction based on the optimal allocation scheme is 56 6695 billion yuan less than that based on the government allocation scheme the gini coefficient of the optimal allocation scheme is smaller than 0 3 indicating that this plan considers effectiveness and fairness furthermore we calculate the optimal proportions for the provinces to reduce coal overcapacity based on different capacity utilizations and different national coal production control targets the results show that the optimal proportions for most provinces are approximately the same under different conditions which means the optimal allocation scheme is robust and efficient

stock markets and development this paper asks if financial development especially stock market development affects the level and or the growth rate of economic activity it finds a substantial effect on both current wisdom suggests that the growth effects of financial intermediation could be either permanent or transitory for instance the greenwood jovanovic 1990 henceforth gj model has an ak stucture with no diminishing returns to the reproducible factor and a permanent exogenous improvement in financial structure would cause a permanent increase in the rate of growth on the other hand if the returns to the reproducible factor did diminish better intermediation could lead only to level effects since one should not a priori exclude either growth effects or level effects we shall look for both our search for growth effects will use the gj model our search for level effects will rely on an amended version of the mankiw romer and weil 1992 henceforth mrw structure

time preference the discounted utility model and health the constant rate discounted utility model is commonly used to represent intertemporal preferences in health care program evaluations this paper examines the appropriateness of this model and argues that the model fails both normatively and descriptively as a representation of individual intertemporal preferences for health outcomes variable rate discounted utility models are more flexible but still require restrictive assumptions and may lead to dynamically inconsistent behaviour the paper concludes by considering two ways of incorporating individual intertemporal preferences in health care program evaluations that allow for complementarity of health outcomes in different time periods

risk taking global diversification and growth this paper develops a continuous time stochastic model in which international risk sharing can yield substantial welfare gains through its effect on expected consumption growth the mechanism linking global diversification to growth is an attendant world portfolio shift from safe low yield capital to riskier high yield capital the presence of these two types of capital captures the idea that growth depends on the availability of an ever increasing array of specialized hence inherently risky production inputs calibration exercises using consumption and stock market data imply that most countries reap large steady state welfare gains from global financial integration copyright 1994 by american economic association

financial development and economic growth a meta analysis we analyze 1334 estimates from 67 studies that examine the effect of financial development on economic growth taken together the studies imply a positive and statistically significant effect but the individual estimates vary widely we find that both research design and heterogeneity in the underlying effect play a role in explaining the differences in results studies that do not address endogeneity tend to overstate the effect of finance on growth while the effect seems to be weaker in less developed countries the effect decreases worldwide after the 1980s our results also suggest that stock markets support faster economic growth than other financial intermediaries

hypothetical intertemporal consumption choices the paper extends and replicates part of the analysis by barsky juster kimball and shapiro 1997 which exploits hypothetical choices among different consumption streams to infer intertemporal substitution elasticities and rates of time preference we use a new and much larger dataset than barsky et al furthermore we estimate structural models of intertemporal choice while parameterizing the parameters of interest as a function of relevant individual characteristics we also consider lobehaviorallc extensions like habit formation models with habit formation appear to be superior to models with intertemporally additive preferences

same financial development yet different economic growth why we re study the relationship between financial development and real gdp per capita growth in 48 countries what we find is an interesting evidence that only stock market development has positive effects on growth and that banking development has an unfavorable if not negative effect on growth we examine whether or not these impacts are a product of various financial and economic conditional variables our conditional variables consist of financial liberalization two sets of country development dummies crises in banking and currency dummies the creditor protection index as well as the anti director and corruption indices our results clearly show that the conditional variables of financial liberalization high income level and good shareholder protection mitigate the negative impacts of banking development on growth in contrast the conditional variables of middle income level regional latin american sub saharan african and east asian dummies banking and currency crises good creditor protection and higher corruption strengthen the negative impacts of banking development on growth next the conditional variables of middle income level latin american sub saharan african and east asian dummies strengthen the positive impacts of stock market development on growth whereas the conditional variables of financial liberalization mitigate the positive impacts of stock market development on growth last we find that the relationship between growth and bank development is better described as a weak inverse ushape this inverse u shape becomes stronger when additional stock market variables are squared thus financial development and growth may in fact be in a nonlinear form

the predictive validity of prospect theory versus expected utility in health utility measurement most health care evaluations today still assume expected utility even though the descriptive deficiencies of expected utility are well known prospect theory is the dominant descriptive alternative for expected utility this paper tests whether prospect theory leads to better health evaluations than expected utility the approach is purely descriptive we explore how simple measurements together with prospect theory and expected utility predict choices and rankings between more complex stimuli for decisions involving risk prospect theory is significantly more consistent with rankings and choices than expected utility this conclusion no longer holds when we use prospect theory utilities and expected utilities to predict intertemporal decisions the latter finding cautions against the common assumption in health economics that health state utilities are transferable across decision contexts our results suggest that the standard gamble and algorithms based on should not be used to value health

opening a stock exchange abstract a large body of theoretical and empirical literature has established a positive relationship between levels of stock market development and economic growth however previous empirical work has been based on samples of approximately 40 countries with the most highly developed financial systems since 1950 over 70 countries have opened their first national stock exchanges can such exchanges increase economic growth i present a data set of my construction that describes the exchange openings that occurred between 1960 and 1998 and find that these exchanges have generated increases in growth during their first 5 years of existence although the longer term results are ambiguous

tests of utility independence when health varies over time in the conventional quality adjusted life year qaly model people s preferences are assumed to satisfy utility independence when health varies over time utility independence implies that the value attached to a health state is independent of the health state that arise before or after it two separate studies were conducted involving a total of 155 respondents in study one we conducted five tests of utility independence using a standard gamble question three of the tests of utility independence were repeated in study two after randomisation was introduced in order to take account of possible ordering effects utility independence holds in the majority of cases examined here and so our work generally supports the use of utility independence to derive more tractable models

frames of reference and the quality of life asked to choose most people state confidently that they would rather be killed in an automobile accident than to survive a quadraplegic and so we are not surprised to learn that severely disabled people experience a period of devastating depression and disorientation in the wake of their accidents what we do not expect however are the speed and extent to which many of these victims accommodate to their new circumstances within a year s time many quadraplegics report the same mix of moods and emotions as able bodied people do there is also evidence that the blind the retarded and the malformed are no less happy than other people ads for the new york state lottery show participants fantasizing about how their lives would change if they won i d buy the company and fire my boss people who actually do win the lottery report the anticipated rush of euphoria in the weeks after their good fortune followup studies done after several years however indicate that these people are no happier indeed are in many ways less happy than before as a young man fresh out of college i served as a peace corps volunteer in rural nepal my one room house had no electricity no heat no indoor toilet no running water the local diet offered little variety and virtually no meat and yet at no time during my two year stay in nepal did i experience a sense of material deprivation on the contrary my monthly stipend of 40 was much more than most others in my village had and with it i experienced a feeling of prosperity that i have recaptured only in recent years these observations illustrate the critical role of context as a determinant of human satisfaction the neoclassical economic model of choice abstracts from context saying that utility depends only on the level of consumption consumption levels obviously are important and the neoclassical model performs reasonably well in many instances and yet its narrow focus misses something important to predict people s behavior to draw inferences about their well being or to make intelligent policy decisions we must not only know the relevant levels of consumption but also have an appropriate frame of reference within which to evaluate them

the correction of tto scores for utility curvature using a risk free utility elicitation method this paper describes and employs a new method to correct time tradeoff tto scores for utility of life duration curvature in contrast to most previous attempts to do so it uses a risk free method that corresponds well to the risk free properties of the tto method in addition the method is robust to several biases that occur under methods that incorporate risk our results show a significant degree of curvature in utility of life duration and therefore a clear bias in tto scores the risk free method seems to be useful to correct tto scores for this influence and leads to significantly higher quality adjustment factors

experienced vs described uncertainty do we need two prospect theory specifications this paper reports on the results of an experimental elicitation at the individual level of all prospect theory components i e utility loss aversion and weighting functions in two decision contexts situations where alternatives are described as probability distributions and situations where the decision maker must experience unknown probability distributions through sampling before choice for description based decisions our results are fully consistent with prospect theory s empirical findings under risk furthermore no significant differences are detected across contexts as regards utility and loss aversion whereas decision weights exhibit similar qualitative properties across contexts typically found under prospect theory our data suggest that for gains at least the subjective treatment of uncertainty in experience based and description based decisions is significantly different more specifically we observe a less pronounced overweighting of small probabilities and a more pronounced underweighting of moderate and high probabilities for experience based decisions on the contrary for losses no significant differences were observed in the evaluation of prospects across contexts this paper was accepted by george wu decision analysis

the validity of qalys under non expected utility this paper examines applications of non expected utility in the health domain the most widely used utility model in health economics the time linear qaly model assumes i separability of quality of life and life duration and ii linearity of the utility for life duration we perform new tests which are robust to violations of expected utility of these two assumptions the data support separability but show that the utility for life duration is concave rather than linear the finding of concave utility may not be surprising in itself the contribution of this paper is to demonstrate this empirically without being invalidated by violations of expected utility it has by now been widely recognised that expected utility is not valid as a descriptive theory of decision under uncertainty the descriptive violations of expected utility have led to the emergence of several non expected utility theories the increasing importance of non expected utility makes it necessary to reassess applications that were previously based on expected utility examples of such reassessments include karni and safra 1989 crawford 1990 and dekel et al 1991 for game theory machina 1995 and wakker et al 1997 for insurance theory and cubitt and sugden 1998 for the evolution of preferences see starmer 2000 for a review the present paper examines applications of non expected utility in the health domain we focus on the main utility model in health economics the quality adjusted life years qaly model and present new theoretical foundations for and empirical tests of this model under non expected utility qalys provide a simple way to combine the two dimensions of health life duration and health status into a single utility index they are intuitively appealing which facilitates communication to policy makers and analytically tractable which explains their widespread use in practical studies a disadvantage of qalys is that they only represent individual preferences over health under strong assumptions if these assumptions do not hold then the use of qalys may lead to incorrect policy recommendations to gain insight into the validity of qalys it is necessary to assess the restrictiveness of the assumptions that the qaly model imposes in the most common version of the qaly model the time linear qaly model the utility of the health outcome of spending t years in health state q is equal to tv g where v is a utility function over health states that is in the time linear qaly model the utility for duration is linear it is well known that under expected utility linearity of utility implies risk neutrality as it turns out risk neutrality with

the effect of financial development on economic growth a meta analysis in this article we contribute to the current debate on the sign and size of the finance growth relation to this purpose we use a meta analysis with 551 estimates from 68 empirical studies that t

policy and regulatory responses to coalmine closure and coal resources consolidation for sustainability in shanxi china abstract the late 1990s and early 2010s witnessed china s efforts to reform its coal industry towards sustainability a series of rigorous initiatives were launched to consolidate its coal resources and upgrade its mining sector the mine closure and production reduction campaign mcprc and coal resources consolidation campaign crcc were among the notable this paper conducts a general review of the policies and regulations relating to these initiatives with shanxi one of the key coal producing provinces and one of the pilot areas for reform as a case study the paper argues that the one size fits all approach may have brought short lived political and economic benefits however in the long run a rationally designed stable socio economically and environmentally co ordinated regulatory framework for both large and small coal mines is needed for the sustainable development of china s coal sector this finding would be helpful for the potential similar reform initiatives for the coal sector and for the wider energy sector across the country

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

an experimental test for risk aversion abstract this paper evaluates an experimental method to measure attitudes to risk in individual subjects the method is applied to study the degree of risk aversion of 46 subjects the results lead us to reject a working hypothesis of risk neutrality for such experimental subjects

discount rates inferred from decisions an experimental study two hundred and four students of economics and finance participated in an intertemporal choice experiment which manipulated three dimensions in a 4 4 4 factorial design scenario postponing a receipt postponing a payment expediting a receipt expediting a payment time delay 0 5 1 2 and 4 years and size of cashflow 40 200 1000 and 5000 individual discount rates were inferred from the responses and then used to test competitively four hypotheses regarding the behavior of discount rates the classical hypothesis asserting that the discount rate is uniform across scenarios time delays and sums of cashflow was flatly rejected a market segmentation approach was found lacking the results support an implicit risk hypothesis according to which delayed consequences are associated with an implicit risk value and an added compensation hypothesis which asserts that individuals require compensation for a change in their financial position

eliciting von neumann morgenstern utilities when probabilities are distorted or unknown this paper proposes a new method the gamble tradeoff method for eliciting utilities in decision under risk or uncertainty the elicitation of utilities to be used in the expected utility criterion turns out to be possible even if probabilities are ambiguous or unknown a disadvantage of the tradeoff method is that a few more questions usually must be asked to clients also the lotteries that are needed are somewhat more complex than in the certainty equivalent method or in the probability equivalent method the major advantage of the tradeoff method is its robustness against probability distortions and misconceptions which constitute a major cause of violations of expected utility and generate inconsistencies in utility elicitation thus the tradeoff method retains full validity under prospect theory rank dependent utility and the combination of the two i e cumulative prospect theory the tradeoff method is tested for monetary outcomes and for outcomes describing life duration we find higher risk aversion for life duration but the tradeoff method elicits similar curvature of utility apparently the higher risk aversion for life duration is due to more pronounced deviations from expected utility

are small stock markets different abstract recent literature has established a positive correlation between financial development and economic growth while papers such as bencivenga et al j econom theory 67 1995 53 identify potential nonlinearities in this relationship empirical research to date has allowed for only linear relationships this paper uses regression tree techniques to investigate whether the partial correlation between growth and financial development differs based on countries levels of financial and economic development as in previous studies growth and financial development are positively correlated in countries with high levels of market capitalization however this relationship does not appear to hold for countries with low levels of market capitalization

what causes exchange rate volatility evidence from selected emu members and candidates for emu membership countries abstract we allow for monetary real and financial variables to assess the relevant importance of each of the variables to exchange rate volatility in the case of selected emu members and candidate countries ex ante analysis shows that volatility in the polish zloty euro and the hungarian forint euro forex markets can be influenced by the monetary side of the economy on the other hand ex post analysis shows that forex markets in france italy and spain had been influenced during the pre emu era by monetary and real shocks however the irish pound exchange rate per ecu had been affected by only real shocks

a new and more robust test of qalys previous empirical tests of quality adjusted life years qalys the most widely used outcome measure in economic evaluations of health care generally yielded negative results these tests were however for the most part based on expected utility which is now widely acknowledged to be descriptively inaccurate the observed violations might therefore have been caused by violations of expected utility we performed a new test of qalys which is valid under expected utility and under the two most influential non expected utility theories rank dependent utility and prospect theory and found considerable support for the qaly model our findings suggest that qalys may be valid if nonexpected utility formulas are used to compute health state utilities

positive time preference the case for positive time preference is absolutely compelling unless there is an infinite time horizon with the expectation of unending technological advance combined with what we call drastically diminishing marginal utility this finding holds both in the positive and normative senses a corollary is that savings are interest elastic

transactions costs technological choice and endogenous growth abstract hicks a theory of economic history clarendon press oxford 1969 argues that an important aspect of industrial development is the adoption of technologies requiring highly illiquid capital investments the adoption of such technologies becomes economically viable in the presence of low cost financial markets that provide liquidity to investors this observation provides a mechanism by which the costs of transacting in financial markets affect the equilibrium choice of technology productive efficiency and by implication growth we analyze how the costs of financial market transactions affect the set of technologies in use and the equilibrium growth rate transactions cost reductions may depending on the capital structure enhance or reduce growth journal of economic literature classification numbers d90 e13 g14

do workers prefer increasing wage profiles we present survey data challenging the assumption implicit in analyses of labor supply that all else being equal workers prefer declining over increasing wage profiles we test several explanations for our results including that a there is something special about wages e g their association with productivity as opposed to other types of payments that induces the preference for increasing wages b utility depends not only on absolute levels of consumption but also on changes in consumption over time and c respondents who prefer increasing wage profiles are irrational and would change their behavior if the rationale for preferring declining wages were explained

intertemporal tradeoffs for gains and losses an experimental measurement of discounted utility this article provides a parameter free measurement of utility in intertemporal choice and presents new and more robust evidence on the discounting of money outcomes intertemporal utility was concave for gains and convex for losses consistent with a hypothesis put forward by loewenstein and prelec 1992 discount rates declined over time but less so than previously observed under the assumption of linear utility for approximately 40 of our subjects constant discounting provided the best fit the remaining 60 were most consistent with harvey s 1986 power discounting our data provide little support for the popular quasi hyperbolic model which is widely used in economics today we observed an asymmetry in the discounting of gains and losses that unlike earlier findings cannot be explained by a framing effect

the effect of unemployment on consumption an experimental analysis this paper reports on an experiment that investigates the apparently robust phenomenon of over sensitivity of consumption to current income using a particularly simple formulation we also investigate whether individuals correctly respond to their employment status we find that subjects over react our data enables us to investigate where this over sensitivity originates we conclude that economic agents differ in their ability to plan ahead and understand the dynamic process determining their employment status however agents seem able to respond appropriately to changes in the parameters governing their decision processes in that the comparative static predictions of the theory are largely confirmed

portfolio flows volatility and growth abstract we study the realized openness to portfolio flows of economically more developed and less developed countries as it affects future gdp growth outflows of a country s funds into u s securities are predictive of gdp growth suggesting that the benefits of openness outweigh local capital flight both inflows and outflows of funds via local equity securities are predictive of growth which is the evidence of the benefits of openness for less developed countries the effect of inflows is especially strong country specific volatility in flows does not detract from growth and volatility in world wide flows precedes growth overall the evidence is consistent with strong benefits of realized financial integration where the availability of u s markets for local portfolio investment along with equity investment from the outside enhances economic growth

do we really understand the development of china s new energy industry abstract countries all over the world have realized that the key to resolving the dilemma between accelerated energy consumption and reduction in carbon dioxide emission is to actively develop new energy industry many scholars have conducted in depth investigation into the main driving forces of the new energy industry however they often adhere to an assumption that the effect of the driving forces on new energy industry is constant across areas ignoring the spatial heterogeneity in economic phenomena geographically weighted regression gwr model and the use of local sample data to implement parameter estimation can make up for the inadequacies of existing research therefore this paper uses the gwr model to carefully investigate the new energy industry the results show that the impact of economic growth on the new energy industry in the eastern region is higher than in the central and western regions owing to the differences in economic structure and fixed asset investment the impact of foreign energy dependence continuously declines from the eastern region to the central and western regions this is attributable to the differences in natural gas and oil imports technological progress has a similar effect on account of the differences in r d funding and r d personnel investments however the impact of the agriculture industry in the central region is higher than in the eastern and western regions due to the differences in crop acreage and agricultural output this study improves our understanding of the new energy industry and would help local authorities to formulate targeted policies for promoting the growth of new energy industry
