economic growth and productivity a case study of south korea the economic performance that south korea has achieved over the past quarter century is often likened to a miracle recently much interest has been expressed in the driving forces behind the korean economic transformation using the valueadded measure of output christiansen and cummings have shown that technology measured by tfp accounts for about 43 of korean economic growth between 1960 and 1973 this figure is considerably high compared with recent major studies on japanese and singaporean economic growth we found that the value added framework is not appropriate for the description of the structure of the korean economy and re examined the sources of korean economic growth using the gross output framework surprisingly it has been discovered that only 7 of real output growth in the manufacturing sector during the 1962 1981 period is attributable to technological progress these findings parallel those for the japanese and singapore economies

organizational structure communication and group ethics this paper investigates experimentally how organisational structure affects ethics inside a firm maximising firm profits harms outsiders in a vertical treatment one insider unilaterally sets the harm reduction strategy the other accepts or quits in a horizontal treatment the insiders decide by consensus communication treatments create a 2 by 2 design in the data communication makes vertical firms more ethical with voice subordinates feel responsible for what their firms do voice mitigates their responsibility alleviation vertical firms are then more ethical than horizontal firms for which bargaining data reveal a dynamic form of responsibility alleviation and chat data indicate a strong insider outsider effect

risk taking for others under accountability we let subjects take risky decisions that affect themselves and a passive recipient adding a requirement to justify their choices significantly reduces loss aversion this indicates that such an accountability mechanism may be effective at debiasing loss aversion in agency relations

an investigation of the rationality of consumer valuations of multiple health risks after developing a conceptual analysis of consumer valuation of multiple risks we explore both economic and cognitive hypotheses regarding individual risk taking using a sample of over 1 500 consumers our study ascertains risk dollar tradeoffs for the risks associated with using an insecticide and a toilet bowl cleaner we observe the expected positive valuation of risk reductions and find empirical support for a diminishing in the valuation of risk reduction as the extent of the risk reduction increases we also find evidence of certainty premiums for the total elimination of one risk but no strong evidence of additional certainty premiums for the elimination of multiple risks strong reference risk effects are evident as increases in risk were valued much more greatly than were decreases

critical survey endogenous growth theory a critical assessment a critical assessment is made of endogenous growth theory from the perspective of recent developments within economics as a discipline these include its increasing mathematical formalisation its focus upon microfoundations the casual use of econometrics to test models and the incorporation of factors that have traditionally been outside mainstream economics it is found that the theory focuses upon market imperfections and technological progress in a variety of ways and reconstructs their impact upon the macroeconomy as a growth rather than as a level effect whilst the growth rate is endogenised this leads to the problem of multiple equilibria and extremely complex dynamics the generalisation from exogenous growth theory is however associated with even more extreme assumptions and analytical distance from the socioeconomic processes of growth itself copyright 2000 by oxford university press

betrayal aversion evidence from brazil china oman switzerland turkey and the united states comment in a series of binary choice problems we investigate how a chooser s risk taking changes when others share in their personal risk either equally or unequally we find that when the safe option yields inequality the risky option is taken significantly more often on the other hand the inequality resulting from the risky choice does not affect risk taking we also find that choosers tend to be less risk averse in a one person context compared to when the risk also affects the payoff of another c72 d81 z13

state steel and strength structural competitiveness and development in south korea this article introduces the concept of structural competitiveness to explain the rapid development of south korean steel industry three elements of structural competitiveness are state autonomy sound economic policy and indigenous technological capability these elements have a significant bearing on the bargaining capacity of the state autonomous investment decisions labour control the acquisition and absorption of modern technology and ultimately international competitiveness global competitiveness of south korea does not refute the technological dependence of developing countries rather it suggests the kind of socio institutional and economic policy contexts that are often necessary to foster competitive industries

total factor productivity vs realism revisited the case of the south korean steel industry this paper presents key features of the development of the south korean steel industry through the critical examination of an article by truett and truett despite their claim to exhibit realism by use of a translog cost function their methodology has strong affinities with the methods of measuring total factor productivity growth which have long been known as invalid but continue to be applied not least to the experience of east asian countries it will be argued that the theoretical and empirical flaws involved with these methods invalidate their results and corresponding policy implications above all by showing that the assumptions for their calculation do not hold in terms of the economic conditions of the industry the paper points to a different understanding of realism than that conceived by and for their study copyright 2005 oxford university press

deciding for others reduces loss aversion we study risk taking on behalf of others both when choices involve losses and when they do not a large scale incentivized experiment with subjects randomly drawn from the danish population is conducted we find that deciding for others reduces loss aversion when choosing between risky prospects for which losses are ruled out by design subjects make the same choices for themselves as for others in contrast when losses are possible we find that the two types of choices differ in particular we find that subjects who make choices for themselves take less risk than those who decide for others when losses loom this finding is consistent with an interpretation of loss aversion as a bias in decision making driven by emotions and that these emotions are reduced when making decisions for others

responsibility or autonomy children and the probability of self employment in the usa this paper studies the effect of children on the likelihood of self employment having children can change preferences that are central to the decision whether to be self employed on the one hand individuals preference for autonomy and flexibility increases when having children which increases the willingness to be self employed on the other hand having children entails a responsibility over someone else which increases individual risk aversion and decreases the willingness to be self employed using a pooled cross section of 26 years from the general social survey instrumental variable estimates indicate that in the usa having children under the age of 18 in the household decreases the likelihood of being self employed by 11 i e the responsibility effect dominates this effect is considerable as a child decreases the probability of self employment more than the increase associated with being raised by a self employed father one of the main determinants of self employment

semiparametric censored regression models aregression model is censored when the recorded data on the dependent variable cuts off outside a certain range with multiple observations at the endpoints of that range when the data are censored variation in the observed dependent variable will understate the effect of the regressors on the true dependent variable as a result standard ordinary least squares regression using censored data will typically result in coefficient estimates that are biased toward zero traditional statistical analysis uses maximum likelihood or related procedures to deal with the problem of censored data however the validity of such methods requires correct specification of the error distribution which can be problematic in practice in the past two decades a number of semiparametric alternatives for dealing with censored data have been proposed in a semiparametric approach part of the functional form of the model usually the regression function is parametrically specified by the researcher based upon plausible assumptions while the rest of the model is not parameterized 1 while the theoretical literature has produced several semiparametric estimators for the censored data model published applications of these estimators to empirical problems in economics have lagged far behind this paper reviews the intuition and computation of a handful of semiparametric estimators proposed for the censored regression model the various estimators are used to examine changes in black white earnings inequality during the

strategic ignorance and the robustness of social preferences participants in dictator games frequently avoid learning whether their choice to maximize their own earnings will help or hurt the recipient and then choose selfishly exploiting the moral wiggle room provided by their ignorance however this is found in an environment in which the dictator must actively learn the true payoffs so inaction means ignorance does this effect persist when one must actively choose either to be ignorant or to be informed or when one must actively choose to remain ignorant in fact whereas 45 of dictators remain ignorant when one must click to become informed this drops to 25 when one must click in either case and to 3 when one must click to remain ignorant although the exploitation of moral wiggle room is not merely an artifact it is much like social behavior itself subject to environmental and psychological factors that may reinforce or undermine its impact data as supplemental material are available at http dx doi org 10 1287 mnsc 2014 1989 this paper was accepted by uri gneezy behavioral economics

the effect of power imbalances on incentives to make non contractible investments we use an experiment to study the effect of ex post sharing rules on relationship specific investments in an incomplete contracting context we find that no power structure can induce first best investments and that equally productive partners reach more efficient outcomes with a balanced power structure i e equal sharing of returns than with an asymmetric one in addition we find evidence for behavioural effects partners make higher investments and reach higher efficiency levels than own payoff maximisation would suggest this behaviour is in line with a model where decision makers care about social efficiency it is not consistent with inequity averse preferences

a note on coupled lotteries we study the impact of coupling a decision maker s lottery payoffs to those of a peer on the preferred level of risk by means of a lab experiment compared to the benchmark where the lotteries are paid off individually symmetrically coupled payoffs increase the willingness to take risks whereas asymmetrically coupled payoffs have the opposite effect moreover subjects with persistent choices in the different conditions behave more risk averse than subjects with non persistent behavior

how individual preferences are aggregated in groups an experimental study abstract this paper experimentally investigates how individual preferences through unrestricted deliberation are aggregated into a group decision in two contexts reciprocating gifts and choosing between lotteries in both contexts we find that median group members have a significant impact on the group decision but the median is not the only influential group member non median members closer to the median tend to have more influence than other members by investigating the same individual s influence in different groups we find evidence for relative position in the group having a direct effect on influence these results are consistent with predictions from spatial models of dynamic bargaining for members with intermediate levels of patience we also find that group deliberation involves bargaining and compromise as well as persuasion preferences tend to shift towards the choice of the individual s previous group especially for those with extreme individual preferences

world oil production trend comparing hubbert multi cycle curves worldwide shale oil resources in the u s china russia poland and france could mean that potential world oil production could double or triple in the next few decades however not all of these new reserves may be as large or as productive as north dakota s bakken shale oil in addition reserves of shale oil look to be a lot less in relative terms than the reserves of shale gas as evidenced by the price of natural gas in the u s compared to the price of oil this suggests that the u s and world supplies of shale oil may be limited in this article we will look to attempt a different type of forecast for oil using a modified hubbert curve oil production forecast we look at possible world oil production trends rather than just u s oil production trends two interesting comparisons of the world oil production trend to other regional trends are the former soviet union s oil production trend and the u s oil production trend if we compare the current world oil production trend to those previous trends using indexation then we can get an idea of what may happen to world oil production in the future

risk taking for oneself and others a structural model approach economic theory makes no predictions about social factors affecting decisions under risk we examine situations in which a decision maker decides for herself and another person under conditions of payoff equality and compare them to individual decisions by estimating a structural model we find that responsibility leaves utility curvature unaffected but accentuates the subjective distortion of very small and very large probabilities for both gains and losses we also find that responsibility reduces loss aversion but that these results only obtain under some specific definitions of the latter these results serve to generalize and reconcile some of the still largely contradictory findings in the literature they also have implications for financial agency which we discuss

a nonhomothetic generalized leontief cost function based on pooled data factor demand studies of komiya ozaki lau and tamura based upon detailed cross section data on individual production units have found that the nonhomothetic factor limitational nht fl demand system a nonhomothetic version of the leontief fixed coefficient model well explains the data these results however have mostly been ignored in the current literature on flexible functional forms and in fact none of the well known nonhomothetic flexible cost function forms includes the nht fl model i introduce a new nonhomothetic form of the generalized leontief gl cost function which includes the nht fl model as a special case empirical application to a pooled data set of the japanese iron steel industry indicates that his form is superior to the translog diewert wales gl and berndt khaled gl forms copyright 1990 by mit press

social responsibility promotes conservative risk behavior abstract previous studies show that group risk taking can be more conservative than individual risk taking two common but untested reasons for this greater caution are the influence of social responsibility and a tendency to conform to the preferences of others we study changes in risk taking in simple settings where another s risk taking can sometimes be observed and where decisions affect not only one s own payoffs but sometimes also affect those of a passive second party we find that social responsibility leads to more conservative risk behavior in group decision making conformism has a more symmetric effect observing the choice of another tends to lead both individual and social decisions toward whatever the other s expressed risk preference is direct tests fail to link the social behavior we observe to the social preference for distributional fairness common in decision making under certainty

productivity growth and factor prices in east asia the industrial revolution in several east asian countries over the last three decades is one of the most important economic events in the postwar era several recent growthaccounting exercises have found that their extraordinary rate of output growth was due primarily to an equally impressive rate of factor accumulation with little due to technological progress see alwyn young 1992 1995 jong il kim and lawrence lau 1994 susan collins and barry bosworth 1996 since these studies suggest that factor accumulation has been the lead actor in east asia s growth many economists have reached the conclusion that the industrial revolution in east asia can largely be explained in terms of transition dynamics in a neoclassical growth framework see e g paul krugman 1994 n gregory mankiw 1995 if this view is correct the lesson from east asia s experience is that there are no easy solutions for a poor country that seeks to join the league of wealthy nations low levels of investment and education may be the result of bad policies but once proper policies are enacted a poor country faces the grim prospect of a further decline in its already low standards of living as it devotes more resources to investment and education the central point of this paper is that if east asia s growth was largely driven by capital accumulation with little technological progress the return to capital should have fallen dramatically as capital accumulation encounters diminishing returns for example the capital output ratio for korea computed from the national accounts has increased at an average rate of 3 4 percent per year from 1966 to 1990 while that of singapore has increased at an average rate of 3 7 percent per year from 1968 to 1990 by dividing the share of payments to capital in total income by the capital output

opec and venezuelan oil production evidence against a cartel hypothesis abstract this study revisits the opec cartel hypothesis using a case study a test is conducted to see if venezuela has its production granger cause its opec quota or whether the opec quota for venezuela granger causes venezuelan production the results show both occur at different times in the short run opec s oil production quota for venezuela granger causes venezuelan production however shortly after cuts venezuela cheats on agreements suggesting a tit for tat oligopoly game which is not anti competitive in the long run we show that venezuelan oil production granger causes opec s quota for venezuela but not vice versa having venezuelan oil production granger cause opec quotas for venezuela in the long run suggests opec does not coordinate outputs as much as it reacts to them the evidence suggests venezuela is not a part of an opec anti competitive syndicate even though we show that venezuelan oil production is low an alternative explanation for why venezuela and possibly other opec members have low oil production outputs is that institutions and risk aversion not cartel participation is the cause a vector error correction model shows that there is no tendency for venezuelan oil production to converge to opec s quota for venezuela

the hidden advantage of delegation pareto improvements in a gift exchange game this paper analyzes the effect on performance and earnings of delegating the wage choice to employees our results how that such delegation significantly increases effort levels moreover we observe a pareto improvement as the earnings of both employers and employees increase when employers delegate than when they do not interestingly we also find that the employees performance under delegation is higher than under non delegation even for similar wages while there is strong evidence that behavior reflects strategic considerations this result also holds for one shot interactions a possible non strategic motivation explaining the positive reaction to delegation is a sense of enhanced responsibility

the role of responsibility in strategic risk taking we explore play between groups where one member of each 2 person group dictates the play of that group and is therefore responsible for the payoff of the other group member we compare this to play when the game is the same but each person is playing only for herself consistent with the principle of responsibility alleviation described by charness charness g 2000 responsibility and effort in an experimental labor market journal of economic behavior and organization 42 375 384 we find that a sense of responsibility for the welfare of others has an effect while the issue of responsibility does not appear to influence the decisions of 2 3 of the population almost 90 percent of the remaining 1 3 of the population plays a less risky strategy when choosing for a group than when playing only for herself

much ado about hotelling beware the ides of hubbert abstract much economic literature analyzes the hotelling principal little economic literature analyzes the hubbert curve although much controversy surrounds it this difference in emphasis by economists needs to be reconsidered critically and towards that end we attempt to look at both concepts simultaneously we test whether a simple hubbert curve model is a significant determinant of world oil price changes and whether one of the main determinants of the hotelling principle the discount rate also affects world oil prices an autoregressive distributed lag ardl bound testing approach is used to examine the effects of a hubbert index variable and a hotelling discount rate variable on the world wide price of oil results show the discount rate the most important hotelling variable has little effect on oil prices but that the hubbert curve model does show a large effect on oil prices oil is a non renewable natural resource par excellence yet the results suggest that the hotelling principle is not an important determinant for oil prices yet the hubbert curve and the theory surrounding the hubbert curve is an important determinant of oil prices
