natural resources national income and economic growth in africa abstract because standard measures of aggregate income such as gross domestic product gdp do not account for natural resource depletion their use as gauges of economic performance tends to exaggerate the benefits of resource extraction accounting for natural resource depletion in 18 african countries indicates different patterns of growth than those suggested by gdp figures use of the revised measures in analyses of the link between exports and growth suggests that export expansion may generate increases in measured gdp without stimulating increased production in contrast real exchange rate alignment is correlated with growth in both conventional gdp and the revised accounts

oil price volatility and stock price fluctuations in an emerging market evidence from south korea abstract how important are oil price fluctuations and oil price volatility on equity market performance what are the policy implications if volatility turns out to be significant we assess this issue in an economics finance nexus for korea using a vec model including interest rates economic activity real stock returns real oil prices and oil price volatility our main aim is to capture the effects of crude oil prices on the korean economy thoroughly covering the period of the asian financial crisis of 1997 which heavily affected the country and the oil price hikes in the early 1990s after the gulf war south korea was the country most hit by the financial crisis together with indonesia and thailand results indicate the dominance of oil price volatility on real stock returns and emphasize how this has increased over time oil price volatility can have profound effect on the time horizon of investment and firms need adjust their risk management procedures accordingly this increase in dependency has been found in other net oil importing emerging equity markets we test the relationship between oil price movements and economic activity by using modern time series techniques in a cointegrating framework we expand the standard error correction model by examining the dynamics of out of sample causality through the generalized variance decomposition and impulse response function techniques the evidence from persistence profiles also gives important guidelines based on how fast the entire system adjusts back to equilibrium in addition we find the cointegrating relationship to be stable and find that the linear error correction model to be more favorable than an asymmetric 2 period markov switching model

collective bargaining in the public sector the effect of legal structure on dispute costs and wages this paper examines the impact of collective bargaining legislation on dispute costs and wages using a panel of canadian public sector contracts the authors results suggest that policymakers designing collective bargaining legislation face a trade off between reducing dispute costs and increasing wages dispute costs are lower under compulsory arbitration than under the right to strike or when no collective bargaining legislation exists hence a switch to compulsory arbitration could potentially make both the union and the employer better off by reducing dispute costs however the authors find that wages are higher under compulsory arbitration than under other legal structures copyright 1991 by american economic association

the contribution of tourism development to economic growth in the korean economy abstract this study investigates the causal relations between tourism growth and economic expansion for the korean economy by using engle and granger two stage approach and a bivariate vector autoregression var model two principle results emerge from this study first the results of a cointegration test indicate that there is no long run equilibrium relation between two series second the outcomes of granger causality test imply the one way causal relationship of economic driven tourism growth the hypothesis of tourism led economic growth is not held in the korean economy this consequence is supported by testing the sensitivity of causality test under different lag selections along with the optimal lag

behavioral demand effects when buyers anticipate inventory shortages abstract firms often worry about how buyers will react when there is an inventory shortage but the anticipation of facing a shortage may also impact buyer behavior in this paper we use a combination of theoretical modeling computational methods and laboratory experiments to understand buyers search behavior in markets where there is potential for either a costly or costless inventory shortage when inventory shortages are costly to buyers we find their equilibrium purchasing strategy generates a newsvendor problem among the firms in turn experimental data suggests buyer behavior can be explained by prospect theory better than by standard assumptions of fully rational expected utility maximizing agents indicating that potential inventory shortages generate loss aversion among buyers and there is systematic mis identification of the probability with which they will be able to procure an item using computational methods we find firms are able to extract more surplus from behavioral buyers via higher prices than would be predicted by the standard model on the other hand when inventory shortages are not costly to buyers the effect of behavioral biases on the part of buyers is not relevant but in this case there can be a benefit to reducing inventory via a reduction in price competition

newsvendor demand chasing revisited existing research on newsvendor behavior asserts that individuals engage in demand chasing adjusting their order quantities towards prior demand several metrics have been used to identify this heuristic by simulation current metrics are shown to yield excessive false positives indicating demand chasing when the true order generating process is independent of prior demand a simple correlation measure does not suffer from this problem and is proposed here as an alternative to some of the more commonly used measures this paper was accepted by martin lariviere operations management

exports and economic growth evidence from 19th century europe abstract cointegration and granger causality tests on data for six european countries from around the middle of the 19th century to 1913 show that exports and gnp were cointegrated and granger causally related with export led growth in italy norway and sweden

does fact finding promote settlement theory and a test nonbinding recommendations such as provided by fact finders are shown to significantly increase voluntary settlements in bargaining theoretically it is unclear whether recommendations will increase settlement rates a recommendation may reduce outcome uncertainty thereby chilling bargaining and increasing dispute rates on the other hand a recommendation may give the parties a focal point around which an agreement is made which of these effects dominates is a question that we consider using theory and data from controlled bargaining experiments the data show the dominance of a focal point effect for suggestions highlighting their potential role in improving dispute settlement procedures

does resorting to online dispute resolution promote agreements experimental evidence abstract this paper presents an experiment performed to test the properties of an innovative bargaining mechanism called automated negotiation used to resolve disputes arising from internet based transactions the main result shows that the settlement rule tends to chill bargaining as it creates incentives for individuals to misrepresent their true valuations which implies that automated negotiation is not able to promote agreements however this perverse effect depends strongly on the conflict situation when the threat that a disagreement occurs is more credible the strategic effect is reduced since defendants are more interested in maximizing the efficiency of a settlement than their own expected profit the implications of these results are then used to discuss the potential role of public regulation and reputation mechanisms in cyberspace

learning and the time interdependence of costa rican exports abstract exports may enhance learning through production induced learning by doing learning to export by doing and flows of information from customers we provide evidence on the learning effects of export destination for costa rica for 1955 through 1980 we examine granger causality results and export trends to determine relationships between exports to the central american common market cacm the rest of the south and the north increasing exports to the cacm appear to promote learning in machinery leather and intermediate manufactures we also find that the cacm redirects some exports away from northern markets probably with damaging consequences

export led growth and structural change evidence from malaysia many studies have tried to establish the causal link between export expansion and economic growth this contribution is to recognize that structural changes will change the sources of growth and this will affect the export growth relationship a country case study approach is used focusing on malaysia a country with one of the world s highest sustained growth rates and a long history of commodity trade we use var analysis of malaysian quarterly trade and gdp growth from 1965 to 1996 trade data are disaggregated into primary and manufactures exports and causality tests are applied to the entire period as well as two subperiods 150 the 1965 1501980 period when policy emphasis was on import substitution and the 1981 1501996 period when policies favoured export led growth statistical tests confirm export led growth for the full period and for the period to 1980 but tests on the 1981 1501996 period show growth causing exports primary exports had a stronger direct impact on economic growth than manufactu

exports and growth is the export led growth hypothesis valid for provincial economies this paper re examines the export led growth hypothesis using provincial data unlike other studies that concentrate on country level data this study investigates the validity of the hypothesis for four largest provinces in korea seoul kyunggee kyungnam and pusan the causal implication of the export led growth hypothesis is generally supported for all provinces in the sample the framework of analysis is two and four variable autoregressive models that include provincial exports provincial output terms of trade and national output shocks granger causal orderings from exports to output growth are generally supported in bivariate causal models in multivariate models variance decompositions and impulse response functions further indicate that export growth has a significant impact on output growth for all provinces although a feedback effect from output to export growth appears in seoul and the kyungnam province

a dynamic migration model with uncertainty we study a dynamic version of the harris todaro migration model where a finite population of infinitely lived bayesian agents choose consumption and migration decision rules as a function of their histories the agents do not know the production functions in the two sectors and learn about them through wage draws that they receive from the stochastic production functions the government knows the true production functions but is uninformed about the agents beliefs and the actual wage draws they observe the government maximizes its welfare function using wage subsidies in the two sectors and a migration tax we solve the agents dynamic programming problem and then use the solution to solve the government s dynamic programming problem we study the effects of government policies on the population distribution and illustrate the model by numerically solving a particular parametric example

exports investment efficiency and economic growth in ldc an empirical investigation this study seeks to analyse the relationship between exports and growth for 19 less developed countries it utilizes multivariate causality analysis based on the error correction model to address several important hypotheses the results indicate that when exports have a causal influence in the development process that in general this is the result of their effect on both efficiency and accumulation in addition improvements in output and capital accumulation in an economy seem to have just as much of an influence on exports as exports have on output and capital accumulation finally the growth process in east asia seems to be quite different from that in southeast asia

impulse balance in the newsvendor game abstract one striking behavioral phenomenon is the pull to center bias in the newsvendor game facing stochastic demand subjects tend to order quantities between the expected profit maximizing quantity and mean demand we show that the impulse balance equilibrium which is based on a simple ex post rationality principle along with an equilibrium condition predicts the pull to center bias and other more subtle observations in the laboratory newsvendor game

rewarding performance by promotion to a different job abstract use of promotions rather than performance related pay to provide incentives can be justified if performance is non verifiable information this does not explain why promotion is to a different job rather than simply a better paid job the effectiveness of tournaments is undermined however if unsuccessful workers are equally suited to higher paid jobs and can engage in bribery or other influence activity a promotion based reward structure with pay tied to jobs can be made immune to such activity if misallocations of employees to jobs are costly to the firm

relationship between agricultural growth and farm imports in ldcs a sims causality test based on 35 countries abstract previous empirical studies on the relationship between agricultural growth and farm imports in the ldcs suffer from serious methodological defects which to some extent may invalidate their results and interpretations this study used sims causality test to examine interactions between agricultural output and agricultural imports for 35 ldcs individually it was found that there was no causality from agricultural output to agricultural imports for a majority of countries under study for countries where agricultural growth did have a causal effect on agricultural imports the effect was positive in some countries and negative in others

causality between export growth and industrial development empirical evidence from the nics a comment abstract in a recent article chow 1987 argued that his empirical evidence supports the hypothesis that export growth causes industrial development in this comment i point out several serious shortcomings of chow s analysis

export instability and the domestic economy questions of causality the conventional view concerning the impact of export instability on the domestic economies of developing countries is one of pessimism export instability is thought to adversely affect the short run stability and longer run growth of income empirical evidence on these matters is however inconclusive this article applies a granger sims reduced form approach to examining whether export instability generates short run instability in domestic income for each of a sample of 20 trade dependent countries the results obtained strongly support the contention that export instability induces short run macroeconomic instability

public sector debt dynamics the persistence and sources of shocks to debt in 10 eu countries this paper characterises the time series properties of debt gdp ratios in ten eu countries over the period 1982 2009 it establishes that shocks to debt ratios persist and measures the size and source of the permanent effects of shocks as they evolve over time the analysis shows that debt dynamics in the eu10 are complicated involving important inter country interactions and protracted adjustment periods of the order of ten years we find evidence of asymmetries in the effects of different forms of fiscal consolidation with unanticipated reductions in government spending having a more permanent effect than unanticipated increases in government revenue unanticipated business cycle fluctuations also have important long term effects on the ratio

testing for unit roots in panel data are wages on different bargaining levels cointegrated theoritical considerations suggest that spillover forces equalize wages for similar jobs thus it is expected that firm wages are cointegrated with the corresponding wage rates on an industrial level in this paper we apply various unit root tests to a panel of wage data we show that the familiar techniques can be adopted to this type of data allowing for unobserved heterogeneity and common time effects our results suggest that firm and industry wages both possess a unit root in the autoregressive representation however ther is only weak evidence for a cointegration realtionship

the dynamic effects of aggregate demand and supply disturbances we interpret fluctuations in gnp and unemployment as due to two types of disturbances disturbances that have a permanent effect on output and disturbances that do not we interpret the first as supply disturbances the second as demand disturbances demand disturbances have a hump shaped mirror image effect on output and unemployment the effect of supply disturbances on output increases steadily over time peaking after two years and reaching a plateau after five years

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

negotiation under possible third party resolution abstractthe effect of a possible third party resolution on negotiation behavior is studied in an economic bargaining experiment the bargaining phase is preceded by a production phase that allows for different fairness principles to guide the division of the total production value the experimental results show that a possible third party resolution lowers the dispute costs by reducing the number of rounds of alternating offers in the presence of a third party negotiators make first offers that are more strongly related to their production which reduces the number of bargaining rounds the production phase has an effect on the distributional property of the agreements in negotiations in which third party resolution is an option the negotiation outcome shifts toward a more unequal outcome more in line with each person s contribution

is the export led growth hypothesis valid for australia the relationship between exports and output is examined using australian annual data over the period 1900 1993 cointegration and causality testing fails to detect the existence of a long run or short run relationship between the two variables these results are explained by restoring to the structural time series modelling approach which shows that while the output series exhibits cyclical variation the exports series does not have this property it is concluded that the export led growth hypothesis is not valid for australia

dispute resolution or escalation the strategic gaming of feedback withdrawal options in online markets many online markets encourage traders to make good after an unsatisfactory transaction by offering the opportunity to withdraw negative reputational feedback in a dispute resolution phase motivated by field evidence and guided by theoretical considerations we use laboratory markets with two sided moral hazard to show that this option contrary to the intended purpose produces an escalation of dispute the mutual feedback withdrawal option creates an incentive to leave negative feedback independent of the opponent s behavior to improve one s bargaining position in the dispute resolution phase this leads to distorted reputation information and less trust and trustworthiness in the trading phase buyers who refuse to give feedback strategically even when it comes at a personal cost mitigate the detrimental impact it is also mitigated in markets with one sided moral hazard and a unilateral feedback withdrawal option the supplementary appendix is available at https doi org 10 1287 mnsc 2017 2802 t

exports imports and economic growth in south korea and japan a tale of two economies this article investigates the relationship between exports imports and economic growth for south korea and japan by constructing a vector autoregression var model causality is examined between real gross domestic product gdp real exports and real imports several principal results emerge from the empirical work first the three variables are cointegrated for both countries implying that a long run steady state exists second there is evidence of bidirectional causality between imports and economic growth for both countries finally japan seems to experience export led growth while gdp growth in south korea has a negative effect on export growth these contrasting findings could result from export goods in japan exhibiting greater nonprice competitive aspects although their success fails to trigger a virtuous circle since growth fails to lead to increased exports while for south korea output growth leads to a decrease in export growth suggesting a strong domestic market

the long run impact of foreign shocks to the austrian economy an analysis at a sectoral level this paper investigates the long run impact of foreign shocks on the austrian economy which is an example of a small open economy with a fixed echange rate regime the analysis is done in a multisectoral vector autoregression framework foreign shocks involve inovations in gnp of european oecd countries oil prices effective echange rate and interest rates sectoral responses appear to be very different in particular shocks to european oecd gnp have a high long run impact on sectoral output especially in export dependent sectors this supports the hypothesis of export led growth

stochastic trends and economic fluctuations are business cycles mainly the result of permanent shocks to productivity this paper uses a long run restriction implied by a large class of real business cycle models identifying permanent productivity shocks as shocks to the common stochastic trend in output consumption and investment to provide new evidence on this question econometric tests indicate that this common stochastic trend cointegration implication is consistent with postwar u s data however in systems with nominal variables the estimates of this common stochastic trend indicate that permanent productivity shocks typically explain less than half of the business cycle variability in output consumption and investment copyright 1991 by american economic association

the validity of the elg hypothesis in the mena region cointegration and error correction model analysis the export led growth elg hypothesis is examined for nine middle east and north africa mena countries in three variable vector autoregressive and error correction models when considering total exports the results reject the elg hypothesis in almost all of these countries when only manufactured exports are examined no support is found for elg in countries with relatively low shares of manufactured exports in total merchandise exports but strong support in countries with relatively high shares these findings suggest that promoting exports may contribute to economic growth only after a certain threshold of manufactured exports has been reached

unit roots and cointegration in estimating causality between exports and economic growth empirical evidence from the asean countries abstract this paper utilizes cointegration and error correction representation methodology in estimating the long run behavioral relationship between exports and economic growth in the asean countries

growth and exchange rate volatility a panel data analysis the aim of this article is to assess the role of real exchange rate rer volatility on long run economic growth for a set of 82 advanced and emerging economies using a panel data set ranging from 1970 to 2009 with an accurate measure for exchange rate volatility the results for the two step system generalized method of moments gmm panel growth models show that a more less volatile rer has a significant negative positive impact on economic growth the results are also robust for different model specifications

foreign growth and domestic performance in a small open economy abstract in this paper we develop a small open economy model of trade with endogenous growth induced by human capital accumulation to analyze the effects of foreign growth on the domestic growth performance stronger foreign growth has the potential to increase domestic growth through a change in the terms of trade for this to happen the domestic attitude toward saving as indicated by the intertemporal elasticity of substitution plays a crucial role for economies with sufficiently thrifty consumers changes in the terms of trade generate funds for domestic investment thereby generating enhanced long term growth if however domestic consumers are less prone to thriftiness foreign growth may lead to lower domestic output growth this result suggests that foreign growth is not necessarily a substitute for a weak domestic attitude toward saving

an empirical investigation of the causal relationship between openness and economic growth in china this study investigates the causal relationship between openness and economic growth in china the integration and cointegration properties of the data are analysed and the models of granger sims geweke and hsiao are used to identify a bi directional causal relationship between gnp and exports plus imports this bi directional causation is consistent with china s development strategy of protected export promotion

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

the economic case for international labour standards this paper explores the economic case for international labour standards granting workers rights of free association and collective bargaining confers both static and dynamic economic efficiencies static efficiencies refer to one time gains from improvements in economic practice dynamic efficiencies refer to gains from improvements to the growth path resulting from a shift away from a low road development path to a high road path these efficiencies raise wages employment and output in developing countries and they can also benefit workers in developed countries labour standards are an institutional mechanism for raising the quality of growth in both developing and developed countries in this sense they are a win win institution

cointegration causality and export led growth in mexico 1895 1992 abstract cointegration and granger causality tests show that real exports and real gdp in mexico over 1895 1992 were cointegrated and there was a significant and positive granger causal relationship running from exports to economic growth

persistence of shocks and their sources in a multisectoral model of uk output growth this paper develops a multisectoral framework for the measurement of persistence of shocks to sectoral and aggregate output and provides a decomposition of the contribution of shocks from different sources to the overall persistence measure the framework is applied to u k output data distinguishing four types of macroeconomic shocks innovations in money supply growth stock returns exchange rates and oil prices among the macro shocks exchange rate shocks have the largest persistence effects on aggregate output through their effects on manufacturing sectors the contribution of the identified macro shocks to total persistence was small however compared to that of sector specific shocks copyright 1992 by royal economic society

a comparison of conventional final offer and combined arbitration for dispute resolution two widely used forms of arbitration are conventional arbitration in which the arbitrator makes an unconstrained settlement choice and final offer arbitration in which the arbitrator must choose between disputants final offers under an innovative as yet unused approach called combined arbitration if the arbitrator s notion of a fair settlement lies between the disputants final offers final offer arbitration rules are used otherwise conventional arbitration rules are used theoretically by combining the risks that the two standard forms of arbitration pose for disputants who do not voluntarily settle combined arbitration should generate convergent final offers the results of this controlled laboratory study show however that dispute rates are highest in combined arbitration and lowest in conventional arbitration these results challenge the theoretical predictions for combined arbitration as well as claims that final offer arbitration should reduce disputes compared to conventional arbitration the results are however consistent with a simple theory of disputant optimism

causality between exports and economic growth abstract this paper utilizes granger causality tests in investigating the relationship between exports and national income from a consistent data set for 47 developing countries in africa new empirical results as well as suggestions for future research are presented

estimating the narcotic effect of public sector impasse procedures this paper first describes in a relatively nontechnical fashion several econometric techniques that the authors believe should be useful to industrial relations researchers those techniques are then applied to an analysis of whether public sector impasse procedures create a narcotic effect that is a tendency for the bargaining parties once they use the procedures to become increasingly reliant on them in future negotiations the authors reanalyze data from thomas kochan and jean baderschneider s study of the impasse experience of police and firefighters under new york state s taylor law during the 1968 76 period and find that while a narcotic effect did exist as kochan and baderschneider argued that relationship lasted only during the early years of the period and was actually reversed in later years the authors conclude by explaining how such a pattern of results could occur tracing the implications of their findings for public policy and suggesting other research questions that could be anal

testing for aggregation bias in linear models this paper discusses alternative methods of testing for aggregation bias and proposes direct tests of the discrepancy of the macroparameters from the average of the corresponding microparameters and derives tests of aggregation bias in the general case where the parameters of interest may possibly be nonlinear functions of the microparameters the paper also develops a durbin hausman type misspecification test of the disaggregate model these tests are then applied to disaggregate and aggregate specifications of employment functions for the u k economy disaggregated by forty industries copyright 1990 by royal economic society

causality between export growth and industrial development empirial evidence from the nics abstract this paper investigates the causal relationship between export growth and industrial development in eight newly industrializing countries nics results of sims causality test show that for most of the nics there is a strong bidirectional causality between the growth of exports and industrial development these findings support the export led growth strategy in that expansion in exports not only promote the growth of national income but also lead to structural transformation of the developing countries

the bounds test approach for cointegration and causality between financial development international trade and economic growth the case of cyprus this study employs the bounds test for co integration and granger causality tests to investigate the long run equilibrium relationship and the direction of causality between financial development international trade and real income growth for the cyprus economy the results of the study reveal that financial development as measured by broad money m2 international trade and real income growth are cointegrated thus a long run equilibrium relationship can be inferred among these three variables on the other hand granger causality test results suggest that in cyprus the growth in real income stimulates the growth of international trade both exports and imports and the growth of money supply furthermore growth in imports of goods and services also stimulates a growth in exports of goods and services of cyprus although this result contradicts our initial expectations it indicates the importance of capital inflows in cyprus that plays a major role in financing the investments mainly in the tourism

exports growth and causality in developing countries abstract previous empirical studies have interpreted results in regressions of output variables on export variables as providing support for an export promotion development strategy such an interpretation is questionable since these regressions provide no means of determining the direction of causality this paper performs causality tests between exports and growth for 37 developing countries the results cast considerable doubt on the validity of the export promotion hypothesis

exports growth and causality in ldcs abstract using akaike s optimal lag criterion in a granger causality test the causal relationship between export growth and economic growth and vice versa is re examined for 20 countries it is argued that earlier analyses which ignore optimal lags in granger or sims causality tests suffer from certain shortcomings which are overcome by the present approach the results suggest some support for the export promotion hypothesis especially in the case of well known nics and thus differ from previous applications of granger test which did not adopt an optimum lag criterion and which showed no causality from export growth to economic growth in such cases however they are inconclusive in evaluating competing hypotheses

exports export composition and growth cointegration and causality evidence for malaysia this paper comprehensively tests the export led growth elg hypothesis for malaysia for the period 1955 90 using cointegration and causality testing based on hsiao s synthesis of the granger test and akaike s minimum final prediction error criterion the results provide support for the elg hypothesis aggregate exports granger cause real gdp and non export gdp this relationship is found to be driven by manufactured exports rather than by traditional exports

exports and economic growth in industrialized countries the prima facie causal relationships between growth exports and factor inputs capital and labour are investigated in five industrialized countries germany itlay japan united kingdom and united states over the period 1960 87 by analysing a four variable vector autoregressive var model for each country our results indicate that germany and japan experienced export led growth reverse causality between exports and growth is found in the case of the us and uk while to causal relationship between exports and output is found for itlay

cointegration causality and export led growth in portugal 1865 1985 abstract this paper considers the relationship between cointegration and causality and uses tests of cointegration as pre tests for granger tests of causality such methods are utilized on portuguese data 1865 1985 where the export led growth hypothesis is rejected in favour of reverse causality

reinterpreting arbitration s narcotic effect an experimental study of learning in repeated bargaining field evidence suggests that arbitration increases negotiation dispute rates we study repeated bargaining in a laboratory to understand the reasons why our results represent a reinterpretation of an explanation known as the narcotic effect the standard interpretation assumes that the probability of dispute without arbitration is constant across negotiations but field evidence suggests that experienced bargainers have fewer disputes to properly assess arbitration s impact we compare bargainer learning with and without arbitration under otherwise comparable laboratory conditions and develop a model to measure learning we find strong evidence that learning occurs in both cases but is slower with arbitration journal of economic literature classification numbers c78 c92 d77 j52 q 1998 academic press

economic growth export and external debt causality the case of african countries empirical investigation of the export driven economic growth hypothesis has provided mixed results in a bivariate causality framework the problem with such bivariate causality analysis is that there can be an omitted variable which could adversely affect the results this paper looks at the trivariate causality analysis of african countries by introducing external deby servicing as a third variable in the export economic growth analysis the results indicate that there is a feedback or bidirectional causality between external debt servicing economic growth and exports evidence of the 1983 90 subperiod is consistent with the argument that the structural adjustment programmes which were designed to remove economic distortions promote exports and encourage external debt management increased growth in the countries involved

persistence in foreign exchange rates abstract this study examines the long run behavior of seven daily nominal exchange rates using univariate and multivariate persistence measures our results indicate that for some currencies the long run behavior deviates from that of a pure random walk in certain periods the multivariate estimates reflect the effect of both the ems exchange rate mechanism and increased post louvre accord coordinated intervention a large portion of the effect of a shock in one currency on another currency s long run value can be attributed to contemporaneous effects on the other currencies

agricultural exports and economic growth in less developed countries this article examines the contribution of agricultural exports to economic growth in less developed countries ldcs a sources of growth equation is developed from a dual economy model where agricultural and nonagricultural sectors are both divided into export and nonexport subsectors this is then estimated using panel data for 62 ldcs for 1974 1995 results provide evidence that there are significant structural differences in economic growth between low lower middle and upper income ldcs investment in the agricultural export subsector has a statistically identical impact on economic growth as investment in the nonagricultural export subsector the marginal productivities in nonexport subsectors are over 30 lower than those in respective export subsectors from a policy perspective the results suggest that export promotion policies should be balanced

the cyclical component of u s economic activity quarterly data on industrial production and deflated gross national product in the united states from 1947 through 1985 are decomposed into independent nonstationary trend and stationary cycle components using kalman filtering and smoothing techniques estimates of the model parameters imply that at least half of the quarterly innovation in u s economic activity can be attributed to a stationary cyclical component that persists over periods of time as long as five years this finding is inconsistent with the hypothesis that most of the apparent variation in u s economic activity can be attributed to a nonstationary trend component

export expansion and economic growth testing for cointegration and causality this paper develops a multivariate error correction model to test the causality between exports and growth in 15 asian countries 1967 91 the underlying series are tested as non stationary in levels but stationary in first differences the causal factors are cointegrated in five of these countries only causality test results indicate that export expansion causes growth in two third of these countries corrected for simultaneity between the causal factors a country with a large public sector higher level of economic development and which is less vulnerable to external economic shocks is more likely to reap the benefits of export promotion strategies the causal inferences are fairly stable over the sample period

export and production growth evidence from three major wheat exporters of australia canada and the united states this article investigates the robustness of the relationship between export and production growth for three major wheat exporters australia canada and the united states from 1966 to 2000 combining production international trade and development theories a four variable production exports producer price and imports vector autoregressive moving average varma model is developed for each country the causality results show that the hypothesis of export led development is supported by these three major players in the international wheat trade though a bi directional causality is found for canada and the usa variance decomposition and impulse response functions are employed to further investigate the effects of macroeconomic shocks

long and short term dynamic causal transmission amongst international stock markets abstract this paper investigates the dynamic causal linkages amongst nine major international stock price indexes in order to gauge the causal transmission patterns we employ very recent methods of i vector error correction modeling and ii level var modeling with possibly integrated and cointegrated processes advocated by i toda and phillips econometrica 61 1993 1367 and ii toda and yamamoto j econometrics 66 1995 225 respectively the paper illustrates how such methods may be appropriately augmented in a compatible fashion to unearth previously unfounded linkage properties inherent amongst a system of stock price indexes in particular we demonstrate that previous research by using ordinary difference vars ignored an important component of linkages displayed purely over the long run this untapped evidence essentially provides robust and very useful information to international financial analysts and investors at a substantive level results of this study tend to support the contention offered by several studies in the literature of significant interdependencies between the established oecd and the asian markets and also the leadership of the us and uk markets over the short and long run the levels var however illustrate the japanese market s influence as an additional long run leader findings seem to be plausible given that these three markets us uk and japan have consistently contributed over 75 of global stock market capitalization over the major part of the sample under consideration at a methodological level this analysis also provides a primer for the wealth of applied financial econometric research focusing on dynamic causal inference which involve systems containing possibly integrated and cointegrated processes

non transboundary pollution and the efficiency of international environmental co operation abstract the standard view is that situations where no transborder environmental externalities occur are most efficiently dealt with by national environmental policies rather than by international co operation though this may be the general case non coordinated national policies do not always produce the most efficient international allocation this paper presents four cases in which the allocative outcome of non coordinated domestic policy choices can be improved upon by international environmental co operation the first case refers to the use of environmental policy as a strategic trade instrument the other cases refer to the existence of discrete technologies set up costs and increasing returns to scale the form of international environmental co operation should be adapted to the situation formal international agreements between countries are characterised by high transaction costs and may not always be the most efficient form of co operation

decision bias in the newsvendor problem with a known demand distribution experimental evidence in the newsvendor problem a decision maker orders inventory before a one period selling season with stochastic demand if too much is ordered stock is left over at the end of the period whereas if too little is ordered sales are lost the expected profit maximizing order quantity is well known but little is known about how managers actually make these decisions we describe two experiments that investigate newsvendor decisions across different profit conditions results from these studies demonstrate that choices systematically deviate from those that maximize expected profit subjects order too few of high profit products and too many of low profit products these results are not consistent with risk aversion risk seeking preferences prospect theory preferences waste aversion stockout aversion or the consequences of underestimating opportunity costs two explanations are consistent with the data one subjects behave as if their utility function incorporates a preference to reduce ex post inventory error the absolute difference between the chosen quantity and realized demand two subjects suffer from the anchoring and insufficient adjustment bias feedback and training did not mitigate inventory order errors we suggest techniques to improve decision making

international evidence on the persistence of economic fluctuations abstract this paper presents new evidence on the persistence of fluctuations in real gnp we estimate two measures of persistence nonparametrically using post war quarterly data from canada france germany italy japan the united kingdom and the united states we compare these estimates with monte carlo results from various ar 2 processes for six out of seven countries the point estimates indicate that a 1 shock to output should change the long run unvariate forecast of output by well over 1 low order arma models yield similar conclusions finally we examine the persistence in relative outputs of different countries

an experimental comparison of dispute rates in alternative arbitration systems this paper reports the results of a systematic experimental comparison of the effect of alternative arbitration systems on dispute rates the key to our experimental design is the use of a common underlying distribution of arbitrator fair awards in the different arbitration systems this allows us to compare dispute rates across different arbitration procedures where we hold fixed the amount of objective underlying uncertainty about the arbitration awards there are three main findings first dispute rates are inversely related to the monetary costs of disputes dispute rates were much lower in cases where arbitration was not available so that the entire pie was lost in the event of a dispute this confirms the empirical importance of the so called chilling effect on bargaining that has been conjectured is produced by the adoption of arbitration systems second the dispute rate in a final offer arbitration system is at least as high as the dispute rate in a comparable conventional arbitration system contrary to the usual argument we find no evidence that final offer arbitration eliminates the chilling effect third dispute rates are inversely related to the uncertainty costs of disputes dispute rates were lower in conventional arbitration treatments where the variance of the arbitration award was higher and imposed greater costs on risk averse negotiators our results can also be interpreted as providing tentative evidence that the negotiators were risk averse on average finally we find general agreement between the dispute rates in our experiment and dispute rates found in the field in comparable settings

innovative activity over the business cycle this paper examines cyclical patterns of innovative activity in the united kingdom over the period 1948 83 innovative activity turns out to have many of the properties of a random walk but does show a tendency to cluster during booms there is clear evidence of a long term secular relation between the level of innovative activity and the level of economic activity although this may have changed in the 1980s finally the data provide no reason for thinking that these clusters of innovation cause cyclic variations in economic activity but variations in economic activity do granger cause changes in innovative activity copyright 1995 by royal economic society

compulsory arbitration arbitral risk and negotiated settlements a case study in bargaining under imperfect information the effect of conventional and final offer compulsory arbitration on negotiated settlements is characterized using nash s variable threats bargaining solution with particular attention to the interaction between arbitral risk and bargainers risk preferences when there is no arbitral risk both schemes are shown to have the same effect on negotiated settlements under very general conditions even when bargaining is over several issues whether or not there is arbitral risk negotiated settlements favour a bargainer more if his opponent is more risk averse on the other hand increases in arbitral risk need not improve the position of the less risk averse bargainer as a by product of the analysis kihlstrom roth and schmeidler s risk sensitivity results for the nash and raiffa kalai smorodinsky solutions are generalized from fixed threats to variable threats bargaining

sectoral shocks and business cycles a disaggregated analysis of output fluctuations in the uk in this paper we first show that it is possible to modify linear real business cycle models to allow for disaggregate industry specific factors in the generation of macroeconomic fluctuations we then try to determine the relative importance of aggregate and sectoral shocks by doing principal components analysis on the residuals from a var of output growth rates in 19 uk industrial sectors we find that a significant percentage of the innovations in sectoral output growths can be accounted for by a single unobserved component however since the model only sets an upper bound to the explanatory power of aggregate impulses the importance of using sectoral data to extract additional information to bear on the analysis of economic fluctuations is confirmed by our findings

collective bargaining in the public sector comment in a recent paper janet currie and sheena mcconnell 1991 hereafter cm provide evidence from the canadian public sector suggesting that requiring binding wage arbitration as opposed to granting the right to strike reduces dispute costs but increases wage costs disputes are defined as either an arbitration or a strike this leads them to conclude that compulsory arbitration pareto dominates other forms of legal structure both parties could potentially be made better off from the reduction in dispute costs associated with compulsory arbitration and those responsible for designing collective bargaining legislation face a trade off between reducing dispute costs and changing the division of the rent p 714 they base these important policy conclusions on their empirical evidence on the following relationships
