commodity prices policy target or information variable note the relationship between growth of the monetary aggregates and growth of nominal gnp has become less dependable in the 1980s deposit deregulation and large fluctuations in interest rates have produced sharp changes in the income velocity of money these velocity shifts have at times caused the federal reserve to miss or modify its money growth ranges because of the undependable relationship between money growth and economic activity some policymakers and economic analysts have argued that the federal reserve should pay more attention to commodity price fluctuations this paper examines the proper role for commodity prices in the formation of monetary policy

robust tests for unit roots in the foreign exchange market abstract empirical studies that have tested for unit roots in foreign exchange rate data have assumed independent and identically distributed errors in order to apply dickey fuller test procedures this assumption ignores the temporal dependence of the error sequence present in many simple efficient market tests as discussed in hansen and hodrick 1980 as well as krasker 1980 in this paper we apply unit root test statistics that allow for heterogeneously distributed and mildly dependent error processes and thus provide superior tests of the unit root hypothesis in the case of foreign exchange rates

agriculture diffusion and development ripple effects of the neolithic revolution are the effects of the neolithic revolution still impacting on incomes across the world today i find strong support for this proposition using new country specific estimates of the timing of the agricultural transition and provide evidence that the differences are due to how technological diffusion is accounted for a correction for world migrations since 1500 significantly improves the fit transition year also helps to explain income in 1500 itself and an alternative measure of pre modern development state history has similar ability to predict income in 1500 and 1997

modelling the link between commodity prices and exchange rates the tale of daily data this paper examines daily data on exchange rates and the prices of three commodities traded on the winnipeg commodity exchange the temporal patterns of commodity prices and exchange rates are shown to be similar daily data are significantly non normal with garch models capturing the processes generating the data commodity prices and exchange rates are examined for cointegration using recent tests proposed by johansen and juselius 1990 currency depreciation is shown to granger cause commodity price inflation this information might be useful to central bankers concerned with reducing general price inflation through targeting commodity price inflation it also suggests that macro events have important effects on commodity markets in canada

early starts reversals and catch up in the process of economic development early states like china and india have been experiencing more rapid economic growth in recent decades we show that more rapid growth by early starters has been the norm in economic history and that the reversal of fortune associated with the european overseas expansion was both exceptional and temporary not only was the post 1500 reversal in the process of being reversed after 1960 but also the advantage conferred by early development in the latter period was considerably greater than the growth rate disadvantage that it conferred during 1500 1960 implying a rapid undoing of the first reversal

post 1500 population flows and the long run determinants of economic growth and inequality we construct a matrix showing the share of the year 2000 population in every country that is descended from people in different source countries in the year 1500 using this matrix we analyze how post 1500 migration has influenced the level of gdp per capita and within country income inequality in the world today indicators of early development such as early state history and the timing of transition to agriculture have much better predictive power for current gdp when one looks at the ancestors of the people who currently live in a country than when one considers the history on that country s territory without adjusting for migration measures of the ethnic or linguistic heterogeneity of a country s current population do not predict income inequality as well as measures of the ethnic or linguistic heterogeneity of the current population s ancestors an even better predictor of current inequality in a country is the variance of early development history of the country s inhabitants with ethnic groups originating in regions having longer histories of agriculture and organized states tending to be at the upper end of a country s income distribution however high within country variance of early development also predicts higher income per capita holding constant the average level of early development

does money matter the robustness of evidence from vector autoregressions traditionally empirical macroeconomic research begins with the use of theory to construct a highly restricted structural econometric model the determination of the nature of those restrictions is fraught with difficulty and thus many specification decisions turn out to be largely ad hoc and of dubious validity once these specification issues have been probably inadequately addressed and a structural model constructed it is then estimated using complicated econometric techniques requiring sophisticated computer programs recently an alternative approach to modeling macroeconomic time series has come into wide use this alternative introduced by sims 1980a 1980b suggests the use of vector autoregression var models to analyze time series relationships among macroeconomic variables the fact that the use of this approach has proliferated widely in a relatively brief period of time is due not only to the very persuasive criticisms of traditional methods made by sims see especially sims 1980a but perhaps even more to the perception that specification and estimation problems are greatly simplified the user of the var approach imposes few restrictions and can generally use ordinary least squares estimation procedures the var approach is thus believed to be largely free of the spurious specification assumptions and consequent specification errors necessitated by traditional macroeconometric procedures

the statistical properties of daily foreign exchange rates 1974 1983 abstract this paper examines the statistical properties of daily rates of change of five foreign currencies from 1974 to 1983 the main purpose is to discriminate between two competing explanations for the observed heavy tails of the distribution that the data are independently drawn from a heavy tail distribution which remains fixed over time and that the data come from distributions which vary over time evidence point to the rejection of the first hypothesis further investigations show that the rejection can be attributed to changing means and variances in the data which can be described by a simple statistical model

sex equality and growth abstract we set up a model of economic and demographic long run development where inequality in income and reproductive success polygynous mating plays a central role the model generates a slow and gradual compression of the income gap between landholders and landless together with rising levels of human capital this process spurts at some stage as society endogenously transits into sustained growth simultaneously inequality in income and reproductive success drops society becomes monogamous

commodity price changes and the predictability of economic policy uncertainty in this study we forecast economic policy uncertainty epu using input on 23 commodity price changes we reveal the significant predictability of epu using three forecast combinations this indicates that commodity price changes can be taken as a leading indicator of epu

dollar movements and inflation a cointegration analysis many studies have concluded that changes in us dollar values affect us prices however since exchange rates may reflect underlying economic conditions this result may be spurious if those conditions are ignored recent advances in time series analysis permitted investigation of both the short and long term interactions between the us price level and the yen dollar exchange rate taking into account the effects of changes in domestic economic activity such as income interest rates and monetary policy examination of these interactions helps to determine to what extent the yen dollar exchange rate impacts the domestic price level the finding is that there is no long term relation between the two variables in addition the results suggest that in the short run monetary authorities respond to changes in the consumer price index and japanese exchange rates however the price level does not respond to change in the exchange rate

the statistical distribution of exchange rates empirical evidence and economic implications the abundant evidence that changes in exchange rates have distributions with fatter tails than the normal distribution has led researchers to consider non normal distributions including the student the stable paretian and mixtures of distributions this paper compares the empirical fits of three non normal candidates and the normal distribution for daily changes in the logarithms of exchange rates using maximum likelihood estimation of the parameters and chi square goodness of fit tests the student and mixture of two normals provide the best fits but there is evidence that the distribution parameters may vary over time

china s macroeconomic performance and management during transition since reforms started in 1978 china has combined rapid growth with moderate price stability this paper analyzes china s macroeconomic performance over the past fifteen years with special attention to factors responsible both for the pace of economic expansion and the periodic fluctuations regarding the former the author identifies four sources of stimuli administrative decentralization high levels of fixed capital investment the elastic supply and quality of the labor force and the increasing volume of savings supplemented in recent years by a large inflow of foreign direct investment future growth with stability calls for controlling and implementing banking and fiscal reform

the effects of macroeconomic announcements on commodity prices this article analyzes the immediate reaction of a representative sample of commodity prices and two t bill yields to the unanticipated components of thirteen macroeconomic announcements surprises in the monetary variables cause the majority of the significant commodity price responses while these plus other cyclical surprises such as the unemployment rate cause significant lumber and t bill reactions the results provide strong support for the policy anticipations hypothesis and against the inflationary expectations hypothesis i e that monetary surprises cause changes in real interest rates rather than in nominal rates only as the inflationary expectations hypothesis contends

causality cointegration and control abstract the first sections of the paper show that causality tests can be relevant when considering the effectiveness of a control mechanism rejecting some results in earlier papers the relevance comes from a more careful consideration of what information is available to whom and when compared to previous work the final section of the paper extends this analysis to cointegrated variables when causality is a necessary consequence

identifying monetary impacts on agricultural prices in var models since the mid 1970s a number of studies have used vector autoregressive var models to evaluate the magnitude and timing of macroeconomic impacts on agriculture use of the var method has been viewed as a way to obtain empirical evidence about these impacts that might not emerge from more traditional overidentified and less dynamic econometric models the hope has been that by placing minimal restrictions on var models the true structure of the economic relationships under investigation can be observed while the aim is laudable critics of var models have argued that it has had the unfortunate consequence of obscuring some important structural identification issues and seeming to promise that something can be obtained for nothing cooley and leroy leamer they point out that identifying restrictions are required to give economically interpretable meaning to the results of any simultaneous equation model sem in standard practice identification of var models is obtained implicitly by choice of a choleski decomposition of the covariance matrix of one step ahead forecast errors which is equivalent to imposing a recursive structure for the economy of concern is that the recursive structure may not be believable further as bernanke has observed examination of ad hoc variants of the recursive order implies a strange set of prior beliefs in which the analyst holds strongly that the system is recursive but is not sure in what order the variables should be arranged in response to these concerns several recent papers have pointed out that identification of var models does not have to rely on the assumption that the contemporaneous structure is recursive bernanke sims rather the distinguishing features of a var model are first that identification rests on the assumption that distinct mutually orthogonal behavior shocks drive the economy and second that lagged relationships among the endogenous and exogenous variables if any are left entirely unrestricted given these features a var model must be identified solely by restrictions placed on the contemporaneous interactions among the variables but the identifying restrictions do not have to preclude simultaneity in this paper we elaborate on the structural interpretation of var models and use this analysis to examine monetary impacts on agricultural prices we discuss the identification problem and the implications of a recursive structure we illustrate our points with respect to the three variable model of money industrial prices and agricultural prices that has been used in several articles to evaluate the effects of monetary shocks on price dynamics bessler devadoss and meyers we then introduce a somewhat richer behavioral model of the macroeconomy and its effects a simultaneous model is shown to offer a more believable identification of monetary policy and other macroeconomic shocks than a recursive model and monetary impacts on agricultural prices are assessed

institutions and the long run impact of early development we study the role of institutional development as a causal mechanism of history affecting current economic performance several indicators capturing different dimensions of early development in 1500 ad are used to remove the endogenous component of the variations in institutions these indicators are adjusted with large scale movements of people across international borders using the global migration matrix of putterman and weil 2010 to account for the fact that the ancestors of a population have facilitated the diffusion of knowledge when they migrate the exogenous component of institutions due to historical development is found to be a significant determinant of current output by demonstrating that the relationship between early development and current economic performance works through the channel of institutions and that better institutions can be traced back to historical factors the results of this paper shed some light on how history has played a role in shaping long run comparative development

common trends commodity prices and consumer prices abstract a multivariate cointegration analysis of monthly data for consumer prices in the usa west germany japan on a commodity price index as well as the dm and yen exchange rate indicates that these six variables are driven by one common trend

effects of the monetary macro economy on canadian agricultural prices this paper examines the importance of monetary macro economic variables on canadian agricultural prices using vector autoregressive var modeling the research results suggest that u s monetary macro economic policy as represented by the u s world exchange rate is the most significant monetary factor influencing canadian agricultural price instability the paper also examined how agricultural prices and manufactures prices respond to a monetary shock the results suggest that agricultural prices respond more quickly in the short run but that manufactures prices catch up in later periods this conclusion supports bordos contract length hypothesis and frankel s overshooting hypothesis it does not support tweeten s cost price squeeze hypothesis

statehood experience legal traditions and climate change policies this study investigates how the implementation of modern climate change policies is related to former colonies length of state history and their legal heritage we argue that countries with longer statehood experience around the time of colonization were better equipped to implement the legal philosophies transplanted by their colonial powers therefore the implications of receiving british common law versus french civil law should be particularly important in countries with a greater accumulated history of statehood using a cross section of up to 78 former colonies our results provide support for this hypothesis in particular our estimates demonstrate that common law countries have weaker modern climate change policies than civil law countries and the difference is inflated by a longer statehood experience measured by the length of state history from 1 to 1800 ad legal origin has no effect in areas which by the time of colonization had no statehood experience finally we report similar results for the pattern of labor market regulations jel k15 k31 k32 o44 q54 q58

preindustrial and postwar economic development is there a link everybody knows now that the hardware dimension of development the physical infrastructure for example is a lot easier to put in place than the software to keep it operable which depends on local skills and institutions united nations development programme 1

the informational role of commodity prices in formulating monetary policy a reexamination abstract this paper reexamines the issue of whether commodity prices provide useful information for formulating monetary policy through the application of a recent development in time series methodology developed by toda and yamamoto j econometrics 66 1995 225 250 we found that commodity prices signal the future direction of the economy

stock returns and volatility most asset pricing models postulate a positive relationship between a stock portfolio s expected returns and risk which is often modeled by the variance of the asset price this paper uses garch in mean models to examine the relationship between mean returns on a stock portfolio and its conditional variance or standard deviation after estimating a variety of models from daily and monthly portfolio return data we conclude that any relationship between mean returns and own variance or standard deviation is weak the results suggest that investors consider some other risk measure to be more important than the variance of portfolio returns

option implied expectations in commodity markets and monetary policy abstract in this paper we estimate the dynamic interactions between option implied variance and skewness in agricultural commodity markets and monetary policy using a structural vector autoregressive svar framework we find that an expansionary contractionary monetary policy upwardly downwardly revises commodity markets expectations about the price and volatility path of agricultural products on the other hand our empirical analysis reveals that monetary policy does not have a systematic and timely response to sudden changes in option implied expectations of commodity investors in addition we provide empirical evidence showing the robust forecasting power of agricultural option implied information on monetary policy with r 2 values reaching almost 52

tests of exchange market efficiency fragile evidence from cointegration tests abstract several recent papers have employed engle and granger 1987 cointegration tests to determine whether or not markets are efficient we use a new test for cointegration due to johansen 1988 to examine market efficiency with respect to the us dollar exchange rates for canadian japanese and west german currencies the fragile nature of the test indications suggests that cointegration methodologies cannot be relied upon to provide reliable evidence on market efficiency

alternative indicators for predicting the probability of declining inflation evidence from the us the performance of inflation indicators for predicting the probability of inflation falling inside constant and moving targets is considered with a probit model using us data given the federal reserve system s emphasis on achieving price stability particular attention is given to the target that future inflation will be below recent inflation in contrast with earlier years the unemployment and capacity utilisation rates do not perform well in forecasting the direction of inflation in the mid and late 1990s we suggest that extending the keynesian phillips curve analysis to consider changes in labour market conditions technological advance and worker skills and openness will increase understanding of these issues

can an evolutionary approach to development predict post war economic growth might differences in levels of development prior to the era of industrialisation explain some of the dramatic differences in rates of economic growth across developing countries in recent decades this article explores the logic behind such a conjecture and presents evidence that it is true using population and agrarian densities as proxies for early development basic growth regressions are estimated for a sample of developing countries in 1960 90 and for provinces in one country china in 1978 92 the robustness of the results to the inclusion of other measures including ethnic heterogeneity and social capability is also shown

relative prices and money further results for the united states empirical results support the hypothesis that agricultural prices respond faster than manufactured product prices to a change in money supply in the united states sims vector autoregression var technique was applied in examining this hypothesis the monte carlo integration method was used to test the significance of the impulse responses generated by the var technique

international macroeconomic policy coordination when policymakers do not agree on the true model the authors relax the assumption of the literature on international coordination that policymakers know the true model t wo countries will still be able to agree on a cooperative policy pack age that each believes will improve the objective function relative t o the nash noncooperative solution however the bargaining solution may move the target variables in the wrong direction these points ar e illustrated with monetary and fiscal multipliers taken from simulat ions of ten leading econometric models out of 1 000 possible combina tions of models that could represent u s beliefs non u s beliefs and the true model monetary coordination improves u s welfare in on ly 546 cases copyright 1988 by american economic association

international macroeconomic policy coordination when policymakers do not agree on the true model reply in their paper in this review jeffrey a frankel and katherine e rockett 1988 show that when international macroeconomic policymakers do not agree on the correct macroeconomic model they will still be able to agree on a cooperative policy package that each believes will improve his welfare yet the package may turn out to move target variables in the wrong direction from extensive simulation experiments with ten empirical models frankel and rockett conclude the bargaining solution is as likely to reduce welfare as to improve it but more definitions of cooperation should be investigated p 338 in this paper we propose an alternative definition of a policy bargain to that investigated by frankel and rockett and show that it results in a higher success rate and higher expected utility in cooperation exper iments it follows from our finding that given uncertainty or ignorance about the true model a measure of disagreement is beneficial because it facilitates a simple robustness check for proposed policy bargains as frankel and rockett 1988 p 328 acknowledge it is the countries failure to perceive the true model not their failure to agree with each other per se that alters the standard conclusion regarding coordination i e it is uncertainty not disagreement that leads to failure we go further given the inevitable failure to perceive the true model some disagreement is better than unanimity in error extreme disagreement about the nature of reality however makes robust bargains impossible

common stochastic trends in a system of exchange rates univariate tests reveal strong evidence for the presence of a unit root in the univariate time series representation for seven daily spot and forward exchange rate series furthermore all seven spot and forward rates appear to be cointegrated that is the forward premiums are stationary and one common unit root or stochastic trend is detectable in the multivariate time series models for the seven spot and forward rates respectively this is consistent with the hypothesis that the seven exchange rates possess one longrun relationship and that the disequilibrium error around that relationship partly accounts for subsequent movements in the exchange rates a general consensus has emerged in recent years that many macroeconomic time series such as gnp consumption expenditures disposable income etc can be characterized by a stochastic trend model in particular nelson and plosser 22 described this property as one of being difference stationary so that the first difference of a time series is stationary an alternative trend stationary model where a stationary component is added to a deterministic trend term has generally been found to be less appropriate 1 similarly it has long been recognized that many financial time series such as foreign exchange rates are nonstationary e g in meese and singleton 21 the issue of nonstationary is not merely a statistical curiosity but has several important implications for the modeling of exchange rates for instance many models of exchange rate determination under rational expectations require stationarity assumptions when solving out the expected future values of the fundamentals further there has been some controversy over the appropriate transformations to use when conducting tests of whether the forward rate is an unbiased and efficient predictor of the future spot exchange rate 2 some authors e g frenkel 11 12 have conducted tests in levels while geweke and feige 14
