maximum likelihood estimation of cointegration in exchange rate models for seven inflationary oecd countries abstract we apply the johansen technique to estimate cointegration in a monetary exchange rate model modified for real exchange rate fluctuations and applied to seven inflationary oecd countries we generally find one or more cointegrating vectors and the signs of their coefficients are broadly consistent with the modified monetary model the adjustment coefficients are also examined our statistical testing is based on bootstrapping and generates much more conservative rejection criteria than the use of asymptotic critical values even after a substantial degree of freedom correction power estimates are also presented finally we conclude that the monetary model unmodified for real exchange rate fluctuations would be inadequate

international real interest rate equalization a multivariate time series approach this paper investigates the dynamic behaviour of monthly ex post real interest rates from several countries over the period 1980 to 1991 it is found that real interest rates are stationary over this period and that deviations from real interest parity are significant in the short run but disappear in the long run the latter evidence is established using the concept of co dependent time series proposed by gourieroux and peaucelle 1989 for the analysis of multivariate stationary time series

risk aversion exchange rate uncertainty and the law of one price insights from the market for online air travel tickets we argue that risk aversion driven by exchange rate uncertainty causes a wedge between the domestic and foreign prices of a homogeneous good we test our hypothesis using a unique micro data set from a market with minimum imperfections the empirical findings validate our hypothesis as accounting for exchange rate uncertainty we are able to explain a significant proportion of deviations from the law of one price overall our analysis suggests the possibility of a new solution to the purchasing power parity puzzles

price level trend stationarity and the instruments and targets of monetary policy an empirical note abstract the application of a stationarity test to floating exchange rate period data indicates a trend reverting price level in switzerland with a base money targeting central bank whereas for the countries with interest rate oriented monetary policy germany japan uk usa the data suggest a difference stationary or trend break behavior of the price level

testing the exogeneity of grants to local governments this paper examines the issue of exogeneity of grants both conditional and unconditional with respect to local expenditures the exogeneity weak strong and super tests show that these grants are not exogenous a model of fiscal response to endogenously determined grants is derived and tested on a pooled time series and cross section sample of forty nine upper tier municipalities in ontario 1977 84 the ols and 2sls estimates of reduced form coefficients differ significantly indicating a simultaneity between grants and expenditures the estimated grant coefficients are negative significant and less than one which implies a substitution of grant funds for own expenditures coefficient estimates of other socio economic factors conform to standard results

co integration and error correction models the temporal causality between government taxes and spending several interesting papers have recently considered whether government taxes granger cause government spending or vice versa the findings based on standard granger 6 causality tests are not consistent manage and marlow 10 conclude that when evidence of one way causality exists federal taxes granger cause federal spending while anderson wallace and warner 1 conclude that the evidence supports one way causality in the opposite direction ram 11 reexamining the issue concludes that taxes granger cause spending at the federal level but that spending granger causes taxes at the state and local level von furstenberg green and jeong 13 in another related article examine the tax and spend spend and tax causality issue using a more general vector autoregressive var model they introduce in addition to federal taxes and spending two economic variables the gnp gap and the inflation rate decompose federal spending into several categories and remove the effects of automatic stabilizers when appropriate they find little evidence that taxes granger cause spending and limited evidence that spending causes taxes a finding which corresponds most closely to that of anderson wallace and warner 1 our purpose is to reconsider the causality issue with the aid of co integration and errorcorrection modeling our analysis illustrates with a specific example how sources of causality can be neglected in standard granger causality tests moreover addressing the question of temporal causality between government taxes and spending provides insight as to how different policies might or might not help control the growth of government the results of our estimating various co integration and error correction models with quarterly data suggest bi directional causality between government taxes and spending both for the federal and state and local sectors this finding counters the conclusions of previous studies when annual data are used however our

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

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

earnings quality in uk private firms comparative loss recognition timeliness abstract uk private and public companies face substantially equivalent regulation on auditing accounting standards and taxes we hypothesize that private company financial reporting nevertheless is of lower quality due to different market demand regulation notwithstanding a large uk sample supports this hypothesis quality is operationalized using basu s 1997 time series measure of timely loss recognition and a new accruals based method the result is not affected by controls for size leverage industry membership and auditor size or by allowing endogenous listing choice the result enhances understanding of private companies which are predominant in the economy it also provides insight into the economics of accounting standards

real effects of exchange rate volatility abstract in the presence of exchange rate volatility and internationally differing rates of time preference investment in the stock of domestic capital is shown to proceed beyond or to fall short of the point where the marginal productivity equals the respective rate of time preference if the national rate of time preference is comparatively low high the respective country winds up as a creditor debtor internationally upon an increases in exchange rate volatility domestic capital of a debtor country creditor country decreases increases the long run effect of increased exchange rate volatility on the trade balance cannot be determined unequivocally

new evidence on the export led growth nexus a case study of malaysia this paper revisits the highly debated export led growth hypothesis in a number of different ways using malaysia as a case study first the hypothesis is tested in terms of labour and total factor productivity growth as a potential channel via which exports can affect or be affected by gdp growth considering the impact of imports on gdp and productivity growth serves a similar purpose in addition gdp is trade adjusted to avoid the double counting problem arising from the national income identity second the relationships are examined using the relatively recent toda and yamamoto 1995 causality tests these results have major implications and are necessary to reassess the effectiveness of trade policy as a strategy for economic development 2007 the author journal compilation

a comparison of lag length selection techniques in tests of granger causality between money growth and inflation evidence for the us 1959 86 this paper employs the granger test to examine the causal relationship between growth in the money supply and inflation for the us over the period 1959 to 1986 alternative procedures including bo

a triangular purchasing power parity hypothesis we propose a triangular purchasing power parity ppp analytical framework which is theoretically justified and empirically validated the mechanisms and channels through which a seemingly mystery relationship emerges are deliberated and examined which renders significant implications to international monetary economics finance and business the de facto peg of the rmb to the us dollar together with trade activities and arrangements causes a triangular ppp effect that the dollar euro exchange rate is not a function of the relative prices in the us and euroland instead it becomes a function of the relative prices in the people s republic of china prc and euroland the results are supportive of triangular ppp in a three economy world of the us euroland and prc

real exchange rates and macroeconomics a selective survey the paper discusses real exchange rate issues of industrial and of developing countries for real exchange rates among the key industrial countries we ask what is the best conceptual framework to shed light on this question we look at alternative theoretical approaches and at empirical evidence on the relation among interest rates expectations and depreciation the discussion of developing countries real exchange rates focuses on the link between real exchange rates real wages and the profitability of capital the model highlights the discrepancy between the mobility of capital including in the long run physical capital and

multivariate cointegration analysis and the long run validity of ppp this paper tests the long run validity of ppp using johansen s multivariate cointegration methodology on exchange rates and domestic and foreign price levels monthly data covering the recent flexible exchange rate period of the dm vis a vis 15 currencies le ad to the following conclusion ppp seems to hold in the long run for s ix european currencies the pound lira norwegian krone schilling escudo and peseta however ppp has to be rejected for the united states and the canadian dollar as well as for the belgian franc and the danish krone nevertheless the authors analysis is more favorable to ppp as a long run property of exchange rates than the recent work applying the engle granger regression methodology copyright 1993 by mit press

fiat exchange in finite economies the state of the art of rendering fiat money valuable is either to impose a boundary condition or to make the boundary condition unimportant through an infinite sequence of markets so as to circumvent backward induction we show fiat exchange may nevertheless arise in finite economies if agents have incomplete information about their relative position in the trade cycle or when the barter and autarky equilibria of the one shot trading round support a monetary equilibrium with repeated trades

cointegration tests of purchasing power parity the impact of non traded goods abstract this paper explores the relationship between non traded goods relative prices and the real exchange rate we apply the johansen maximum likelihood procedure to two different data sets of traded and non traded prices first we develop a model which highlights the importance of non traded relative price movements in causing deviations in the real exchange rate away from ppp we find a strong association a rise fall in the domestic relative price of non traded goods is associated with an appreciation depreciation in the real exchange rate while the opposite is true for the foreign relative price we conclude that non traded goods relative price movements are an important determinant of real exchange rate behavior

exports investments and economic development of pre accession countries of the european union an empirical investigation of bulgaria and romania this paper attempts to analyse the relationship between exports investments and economic development in two pre accession countries of the european union bulgaria and romania for investigation of this relationship a multivariate autoregressive var model is used the results of cointegration analysis showed that there is one cointegrated vector among exports investments and economic growth for the two countries granger causality tests based on error correction models ecm indicated that there is a strong granger causal relation between economic growth and exports as well as between investments and exports for the two countries in addition economic development and capital accumulation in an economy seem to have just as much of an influence on exports as exports have on capital accumulation and economic development

ppp strikes back aggregation and the real exchange rate we show the importance of a dynamic aggregation bias in accounting for the ppp puzzle we prove that the aggregate real exchange rate is persistent because its components have heterogeneous dynamics established time series and panel methods fail to control for this using eurostat data we find that when heterogeneity is taken into account the estimated persistence of real exchange rates falls dramatically its half life for instance may fall to as low as eleven months significantly below the consensus view of three to five years

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

fractional cointegration low frequency dynamics and long run purchasing power parity an analysis of the australian dollar over its recent float a relatively new but generalized concept of fractional cointegration is applied to shed some light on the validity of purchasing power parity ppp as a long run equilibrium condition by examining the long run relationship between quarterly consumer price indices and bilateral exchange rates of the australian dollar and seven major oecd trading partners over australia s recent float the paper demonstrates that relaxing the condition that the residual from the cointegration equation must be a i 0 process provides a wide range of cases of parity reversion with processes that are ci 1 d with 0 d 1 findings tend to suggest that while standard tests of cointegration fail to support cointegration between nominal exchange rates domestic and foreign prices and thus the empirical favour for ppp as a long run phenomenon the fractional cointegration analysis permits deviations from equilibrium to follow a fractionally integrated process and hence captures a much wider class of parity or mean reversion

exchange rate uncertainty and foreign trade abstract this paper starts with reviewing the existing literature on exchange rate uncertainty and trade flows it then argues that potential costs of medium term uncertainty in exchange rates and competitiveness are likely to be much larger than that of exchange risk which has been the focus of the existing literature two measures of medium term exchange rate uncertainty are constructed one is a weighted function of the magnitude of past movements in nominal exchange rates and the current deviation of the exchange rate from equilibrium while the second depends on both the duration and the amplitude of misalignment from equilibrium exchange rates the empirical evidence reported in the paper suggests that when exchange rate uncertainty is defined over a medium term period it does affect adversely trade flows of the industrial countries under review with the notable exception of the united states

generalized long memory and mean reversion of the real exchange rate definitive evidence regarding a rapid mean reversion of the real exchange rate is not present when using standard linear methodology including unit root tests and fractional integration to consider the robustness of these results we use an encompassing model the gegenbauer autoregressive moving average garma model which nests as special cases the existing linear methods the garma model accommodates a complete notion of persistence and allows shocks to dissipate slowly in a cyclical manner we find evidence supporting a weak version of purchasing power parity where equilibrium errors are long memory with strongly persistent cycles however this new form of cyclical mean reversion is likely too slow to be economically meaningful the inability to find a strong equilibrium attractor process using a very general encompassing linear methodology provides support for the recent models that allow for a nonlinear attraction process and for shifting real exchange rate equilibria

price uncertainty and the exchange rate risk premium abstract this paper develops a simple two country portfolio model of the exchange rate risk premium which incorporates price uncertainty in both countries it is shown how the risk premium depends on the world shares of outside assets and wealth as well as on the variance covariance matrix of prices and the exchange rate in particular when purchasing power parity holds the distribution of world wealth has no effect on equilibrium asset prices

panel unit root tests of purchasing power parity for price indices abstract this paper adopts four panel unit root tests to evaluate ppp over the floating period for six different price indices results generally support ppp albeit the speeds of adjustment differ considerably between price indices and test procedures the degree of contemporaneous and serial correlation as well as heterogeneity of the series in the panel affect stationarity and the speed of mean reversion

foreign aid poverty reduction and democracy eradication of poverty is the most pervasive goal of donors foreign aid programmes as a result there has been much research on the degree of correlation between aid and poverty reduction however this work to date has shed little light on the direction of causation between the two variables using the method of granger causality and conditioning aid and poverty on the state of democracy in developing countries this study asks whether aid flows impact poverty whether poverty influences aid flows or whether causality proceeds in both directions simultaneously while the results identify no causal relationships in some of the sub samples they point to the existence of a multitude of relationships across others

real exchange rate volatility and international trade a reexamination of the theory one of the issues that have received considerable attention in the comparison of the properties of alternative exchange rate regimes is the effect of exchange rate risk on the volume of trade it has been argued that the higher volatility of exchange rates witnessed since the adoption of the floating regime in 1973 has led to a decrease in international trade transactions this is because most trade contracts are not for immediate delivery of goods and since they are denominated in terms of the currency of either the importer or the exporter unanticipated fluctuations in the exchange rate affect realized profits and hence the volume of trade it is implicitly assumed that forward exchange markets that can help traders eliminate this type of variations in profits either are not available as it is true for the majority of currencies because most are not fully convertible thereby impairing forward markets or for some reason they are not utilized to fully hedge exchange risk present in trade transactions the empirical evidence regarding the effect of exchange rate risk on trade has at best been inconclusive the large majority of the empirical studies are unable to establish a systematically significant link between exchange rate variability and the volume of international trade whether on an aggregate or on a bilateral basis abrams 1 akhtar and hilton 2 cushman 4 5 6 and kenan and rodrik 12 find some significant negative effects of exchange volatility on exports however bailey tavlas and uhlan 3 hooper and kohlhagen 10 and an international monetary fund study 11 do not find any supporting evidence for the depressing effect of exchange rate volatility on international trade it is also interesting to note that in many of these studies a significant positive effect of exchange rate volatility on the volume of trade is found for some cases however the positive effect believed to be at odds with the theory was either ignored or dismissed as a perverse result since as far as volumes are concerned theoretical considerations

cointegration between exchange rates and relative prices another view abstract in this paper the cointegration property of exchange rates and relative prices as implied by the purchasing power parity theory ppp is reexamined using a time varying parameter tvp approach such an approach recognizes the possibility that the lack of cointegration between exchange rates and relative prices found in recent literature may be the result of the nonstationarity of the cointegrating regression parameters themselves the tests of cointegration in a tvp framework indicate that ppp is better supported and point to the presence of structural instability in the long run equilibrium relationship between exchange rates and relative prices

a prism into the ppp puzzles the micro foundations of big mac real exchange rates we match big mac prices with prices of its ingredients as a unique prism to study real exchange rates rers this approach has several advantages first the levels of the big mac rer can be measured meaningfully second as the exact composition of a big mac is known the contributions of its tradable and non tradable components can be estimated relatively precisely third the dynamics of the rer can be studied in a setting free of several biases inherent in cpi based rers finally a large cross country dimension allows us to overturn the engel result on what drives rers in most economies the exchange rate is the single most important relative price one that potentially feeds back into a large range of transactions obstfeld and rogoff 2000

purchasing power parity under the european monetary system abstract using reduced rank cointegration analysis this study examines whether exchange rate realignments are effective in extenuating the deviations from purchasing power parity ppp under the european monetary system ems in contrast to previous studies more positive evidence for the ppp hypothesis is found the difference in findings can be attributed partly to the statistical technique used the correction of the finite sample bias and the adjustment for realignment effects in general the results of this study support that currency realignments of the ems have been effective in maintaining ppp among its member countries

the emergence of cooperation among egoists this article investigates the conditions under which cooperation will emerge in a world of egoists without central authority this problem plays an important role in such diverse fields as political philosophy international politics and economic and social exchange the problem is formalized as an iterated prisoner s dilemma with pairwise interaction among a population of individuals results from three approaches are reported the tournament approach the ecological approach and the evolutionary approach the evolutionary approach is the most general since all possible strategies can be taken into account a series of theorems is presented which show 1 the conditions under which no strategy can do any better than the population average if the others are using the reciprocal cooperation strategy of tit for tat 2 the necessary and sufficient conditions for a strategy to be collectively stable and 3 how cooperation can emerge from a small cluster of discriminating individuals even when everyone else is using a strategy of unconditional defection

long run purchasing power parity in the 1920s abstract this paper presents an empirical analysis of long run purchasing power parity ppp during the 1920s float using recently developed methodology on the cointegration of economic time series our results are generally supportive of ppp as a long run equilibrium condition on which exchange rates tended to converge over the period for dollar sterling however there is some evidence of a non stationary drift away from fundamentals during the last year or so before britain s return to the gold standard perhaps due to speculation our results also appear to reconcile some apparently conflicting evidence in the literature

earnings quality evidence from the field abstract we provide insights into earnings quality from a survey of 169 cfos of public companies and in depth interviews of 12 cfos and two standard setters cfos believe that i above all high quality earnings are sustainable and repeatable specific characteristics include consistent reporting choices backing by actual cash flows and absence of one time items and long term estimates ii about 50 of earnings quality is driven by non discretionary factors such as industry and macro economic conditions iii in any given period about 20 of firms manage earnings to misrepresent economic performance and for such firms 10 of eps is typically managed iv earnings manipulation is hard to unravel from the outside but peer comparisons and lack of correspondence between earnings and cash flows provide helpful red flags in addition cfos disagree with current standard setting on a number of issues including the sheer number of promulgated rules the top down approach to rule making the neglect of the matching principle and the emphasis on fair value accounting they indicate that a rules based culture makes the audit function centralized and mechanical and hinders the development of audit professionals a summary impression from our work is that cfos view earnings quality as more of a single and unconditional characteristic in contrast to current research where measures of earnings quality are strongly conditional on the decision setting this cfo view is related to their idea of one number a single earnings metric that shapes both their interactions with external stakeholders and internal decision making

capital accumulation and the current account in a two country model abstract this paper examines the joint determination of international debt and capital accumulation in a two country model national rates of time preference are endogenous adjusting along an optimal path to come into equality with one another in the steady state the characteristics of short run current account dynamics are crucially linked to world capital accumulation and to a country s long run net external asset position steady state creditor countries tend to have current account surpluses during episodes of world output growth and vice versa for debtor countries this gives rise to possible non monotonic adjustment in the current account and consumption

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

real exchange rates ppp and the relative price of nontraded goods the purchasing power parity hypothesis ppp states that nominal exchange rates move with differences in relative prices between economies the theory has received considerable attention in the economic literature since cassell 6 and is the foundation of many long run theoretical hypotheses in international finance yet its empirical validity remains in question many tests of ppp focus on the stationarity of the real exchange rate the nominal exchange rate adjusted for changes in price levels between economies if domestic and foreign price levels and the nominal exchange rate are integrated then cointegration between these variables implies the existence of both a long run equilibrium relationship and ppp the residual the real exchange rate then follows a stationary process the paper uses the multivariate cointegration methodology of johansen 16 and johansen and juselius 17 18 to examine the source of real exchange rate nonstationarity is the nonstationarity due to shifts in the domestic and foreign price of nontradeables or productivity differentials between traded and nontraded sectors or is the nonstationarity a possible outcome of difficulties in intercountry comparisons of prices movements associated with construction of these price indices most research finds the real exchange rate follows a nonstationary process due to the presence of a unit root 8 12 1 9 19 27 however the existence of a variable trend in the real exchange rate does not imply the absence of a long run relationship between relative prices levels and nominal exchange rates for two reasons first a long run relationship between price levels and nominal exchange rates may exist but not the one for one relationship implicit in the calculation of real exchange rates due to measurement differences in the construction of price indices between economies second ppp violations may occur due to the presence of permanent productivity innovations which affect the relative price of nontradeables if these shocks are not represented by measurable variables a cointegrating relationship will not exist the paper constructs traded and nontraded gdp price indices and productivity rates for 14 oecd economies and tests 1 if the variable trend the nonstationary process in the real exchange rate is due to permanent innovations in relative price of domestic and foreign nontradeables 2 if long run ppp violations are due to permanent movements in the relative price of nontradeables 3 if the nonstationarity in the real exchange rate is due to permanent innovations in domestic and foreign productivity differentials between the traded and nontraded sectors 4 if the variable trend in the relative price of nontradeables is due to permanent innovations in productivity between sectors lastly the paper constructs a cointegrating error correction model

investigating nonlinearities in real exchange rate adjustment threshold cointegration and the dynamics of exchange rates and relative prices abstract motivated by growing evidence of nonlinear mean reverting behavior in real exchange rates this paper investigates the underlying dynamics in the context of a threshold vector error correction model tvecm of nominal exchange rate and relative prices unlike univariate models our nonlinear multivariate framework takes into explicit account the joint behavior and individual dynamics of the nominal exchange rate and relative prices when these two key variables are threshold cointegrated our empirical application unravels their relative contribution to mean reversion and underscores the importance of capturing their interactions in investigating the nonlinear adjustment toward purchasing power parity

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

earnings management to avoid earnings decreases and losses this paper provides evidence that firms manage reported earnings to avoid earnings decreases and losses specifically in cross sectional distributions of earnings changes and earnings we lind unusually low frequencies of small decreases in earnings and small losscs and unusually high frequencies of small increases in earnings and small positive income we find evidence that two components of earnings cash flow from operations and changes in working capital are used to achieve increases in earnings we present two theories based on stakeholder use of information processing heuristics and prospect theory about the motivation for avoidance of earnings decreases and losses

exchange rate pass through when market share matters the authors investigate the pass through from exchange rates to import prices when firms future demands depend on their current market shares they show that profit maximizing foreign firms may either raise or lower their dollar export prices when the dollar appreciates temporarily i e the pass through may be perverse and that current import prices may be more sensitive to expected future exchange rates than to current exchange rates they present evidence that suggests the behavior of expected future exchange rates may provide a clue to the puzzling recent behavior of u s import prices copyright 1989 by american economic association

determinants of export instability in the primary commodity trade of ldc s abstract based on a sample of 61 ldc primary commodity markets an attempt is made to explain inter market variations in price quantity and earnings instability a model similar to that used to explain aggregate export earning instability is tested empirical results point to internal fluctuations as a major determinant of export market instability

exchange rate volatility and exports a firm level analysis the relationship between real exports and exchange rate volatility is investigated using panel data analysis at the firm level results indicate that there is no negative or positive relationship between volatility and real exports in addition firm size and level of international activity do not influence the size and significance of the volatility effect on exports however there is some evidence that firms use import revenue to lower their exchange rate exposure

public pensions as optimal social contracts abstract a simple overlapping generations model is modified to allow for an externality experienced by the young from consumption by the elderly this sets up a game between generations in which one generation s strategy may be to save too little and rely on gifts from the young e g public assistance for retirement income social security can therefore be viewed as a pareto optimal contract to restore efficient intertemporal allocation a funded public pension plan corresponds to forced saving but is vulnerable in that the next young generation may stop contributing rely on its children for retirement assistance and meanwhile reap the consumption externality from the current elderly s social security benefits this suggests a forced giving or pay as you go type of compulsory pension plan such as exists in most nations which also has the advantage of aiding the initial old generation and therefore generating an immediate consumption externality for the initial young the approach can also be used to explain other aspects of existing social security

adjustment costs and pricing to market theory and evidence abstract this paper develops an adjustment cost model of pricing to market the model consists of a monopolist who supplies an identical nondurable good to two foreign markets it is shown that the degree of pricing to market increases with the relative importance of the transitory component in exchange rates customs data from 1978 through 1987 on u s and canadian imports of seven german commodities are used to estimate the model s parameters and test its over identifying restrictions

purchasing power parity price indices and exchange rate forcasts abstract this paper addresses the issue of using aggregate price indices for purchasing power parity ppp tests and the fitness of ppp as a model for exchange rate forecasting compared with consumer price index cpi and wholesale price index wpi the price index of traded goods tpi appears to be a more appropriate price index for both ppp tests and exchange rate forecasting it performs better in the tests and provides superior exchange rate forecasts both within and out of sample while the half life of the estimated deviations from ppp is about two years for the cpi and wpi based real exchange rates it is only one year for the tpi based real exchange rates

effect of investor speculation on earnings management this paper considers how the presence of a speculative investor who bets on a firm s future earnings report affects how the firm s management manipulates that report we examine the influence of the speculator s information on earnings management behavior quality of reported earnings and stock price efficiency we also provide predictions for and interpretations of short window event studies and long window association studies

real earnings management in sales abstract we surveyed 1 638 sales executives across 40 countries regarding their companies likelihood of asking sales to perform real earnings management rem actions when earnings pressure exists using this information which we refer to as companies rem propensities we study how company characteristics and environmental conditions relate to the responses received the use of cash flow incentives for sales personnel and the distribution of interfunctional power in favor of finance rather than sales are both associated with companies rem propensities in addition we show that sales executives preemptively change their behaviors in anticipation of top management s rem requests sales executives working for public companies and companies in the united states reported higher levels of rem propensity the data also support an association between rem propensity and finance sales conflict these findings and others are compared and contrasted with existing empirical and survey based research on rem throughout the paper abstract from author

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

real exchange rates and structural breaks cointegration tests often fail to detect the existence of long term relationships such as purchasing power parity for two reasons i these tests have low power and ii structural shocks can alter the long run real exchange rate in this paper the long run movements of five exchange rates relative to the us dollar and five european exchange rates relative to the deutsche mark are investigated in particular corrected cointegration tests are applied which take into account the possibility of a structural break at an unknown date empirical evidence is found that structural changes can be responsible for most exchange rate deviations from their equilibrium defined by purchasing power parity or a generic monetary model

society land love or money a strategic model of how to glue the generations together abstract the purpose of this paper is to show that if reasonable care is taken in well defining the types of games of strategy which arise naturally from considerations of the multigenerational aspects of any society then many different plausible explanations of intergenerational links will all be consistent with an ongoing economy with intergenerational transfers of wealth given that the problem is stated and deemed to be important what can we do about it in this paper we proceed by developing in highly simplified form the apparatus needed to consider a multistage variable person game of strategy this is applied to several relatively simple examples involving conscious altruism coded or instinctive behavior the threat of social custom and the role of ownership in conclusion it is argued that although the examples analyzed are simple they are examples of general phenomena the level of mathematical analysis itself is kept as a minimum further development calls for a considerable enlargement of notation and further discussion of items such as information games with infinite horizons and the many problems associable with the development of adequate solution theories for games played in extensive form as the stress is upon the modeling problems of glueing the generations together the game theory is presented only as a useful method for furthering this purpose because it stresses the general concepts of strategic analysis it is our belief that it is particularly suited to the analysis of situations in which economic social political and other decisions and motivations must be considered together
