interpreting economic time series this paper explores some of the implications for econometric practice of the principle that people s observed behavior will change when their constraints change in dynamic contexts a proper definition of people s constraints includes among them laws of motion that describe the evolution of the taxes they must pay and the prices of the goods that they buy and sell changes in agents perceptions of these laws of motion or constraints will in general produce changes in the schedules that describe the choices they make as a function of the information that they possess until very recently received dynamic econometric practice ignored this principle the practice of dynamic econometrics should be changed so that it is consistent with the principle that people s rules of choice are influenced by their constraints this is a substantial undertaking and involves major adjustments in the ways that we formulate estimate and simulate econometric models

testing the unbiasedness hypothesis in the forward foreign exchange market a specification analysis abstract this paper evaluates two popular regression methods of testing the unbiasedness hypothesis in the forward foreign exchange market for the 30 day canada united states forward foreign exchange market the evidence overwhelmingly indicates that it is inappropriate to treat the structure of the systematic and stochastic components of the test relations as constant over time hence conclusions inferred from parameter significance testing based upon full sample estimation can be very misleading accordingly we argue for a specification analysis of the test relations and more explicit modelling of market fundamentals

democracy and economic growth a meta analysis despite a sizeable theoretical and empirical literature no firm conclusions have been drawn regarding the impact of political democracy on economic growth this article challenges the consensus of an inconclusive relationship through a quantitative assessment of the democracy growth literature it applies meta regression analysis to the population of 483 estimates derived from 84 studies on democracy and growth using traditional meta analysis estimators the bootstrap and fixed and random effects meta regression models it derives several robust conclusions taking all the available published evidence together it concludes that democracy does not have a direct impact on economic growth however democracy has robust significant and positive indirect effects through higher human capital lower inflation lower political instability and higher levels of economic freedom democracies may also be associated with larger governments and less free international trade there also appear to be country and region specific democracy growth effects overall democracy s net effect on the economy does not seem to be detrimental

a reexamination of purchasing power parity a multicountry and multiperiod study abstract this paper re examines the purchasing power parity ppp theory in a multiple exchange rate world owing to a lack of precision in estimating the parameters many authors concluded that ppp did not hold very well in the 1970s using a time series cross sectional estimation procedure we are unable to reject the hypothesis that ppp holds in several currencies simultaneously in addition the parameters are precisely estimated this result follows from the estimation procedure which allows us to exploit the cross sectional variation in the data and the contemporaneous correlation in the deviations from ppp

bank integration and state business cycles we investigate how integration of bank ownership across states has affected economic volatility within states in theory bank integration could cause higher or lower volatility depending on whether credit supply or credit demand shocks predominate in fact year to year fluctuations in a state s economic growth fall as its banks become more integrated via holding companies with banks in other states as the bank linkages between any pair of states increase fluctuations in those two states tend to converge we conclude that interstate banking has made state business cycles smaller but more alike i introduction the united states banking system was once anything but united until 1978 every state in the union barred banks from other states so instead of one national banking system we had more like 50 little banking systems one per state 1 once states opened their borders to out of state banks bank holding companies marched in and bought up or merged with banks all over the country in 1975 just 10 percent of the bank assets in the typical state were owned by a multistate bank holding company by 1994 this interstate bank asset ratio had risen to 60 percent figure i our paper investigates how the advent of interstate banking integration in the united states has affected economic volatility within states with the united states balkanized banking system the fate of a state and its banks were closely tied as went the state so went the banks the farm price deflation in the early 1980s bankrupted many farmers and many farm banks falling oil prices in the mid 1980s wiped out a lot of texans and a lot of texas banks shocks to commodity prices probably caused these contractions but frictions in the banking sector may have aggravated them by allowing a freer flow of bank capital and lending among states we maintain that interstate banking will reduce the drag that banking frictions can have on economic contractions

sulfur dioxide control by electric utilities what are the gains from trade title iv of the 1990 clean air act amendments caaa established a market for transferable sulfur dioxide so2 emission allowances among electric utilities this market offers firms facing high marginal abatement costs the opportunity to purchase the right to emit so2 from firms with lower costs and this is expected to yield cost savings compared to a command and control approach to environmental regulation this paper uses econometrically estimated marginal abatement cost functions for power plants affected by title iv of the caaa to evaluate the performance of the so2 allowance market specifically we investigate whether the much heralded fall in the cost of abating so2 compared to original estimates can be attributed to allowance trading we demonstrate that for plants that use low sulfur coal to reduce so2 emissions technical change and the fall in prices of low sulfur coal have lowered marginal abatement cost curves by over 50 percent since 1985 the flexibility to take advantage of these chan

purchasing power parity modeling and testing mean reversion abstract a model of mean reversion of exchange rates to purchasing power parity is developed and tested where exchange rates are assumed to follow a mean reverting elastic random walk toward a stochastic ppp rate the model recognizes the possibility that mean reversion towards ppp may be nonlinear which allows greater flexibility in the adjustment process regression equations consistent with the theoretical model are derived the model is tested using long and short term data for six countries while the results are generally consistent with the findings of previous studies evidence is presented which demonstrates that the mean reversion process is not linear for some countries

national price levels purchasing power parity and cointegration a test of four high inflation economies abstract the time series properties of exchange rates and wholesale prices from four high inflation countries show some evidence in support of purchasing power parity tests for stationarity of real exchange rates and cointegration among price and exchange rate variables are presented for argentina brazil chile and israel during the 1970s and 1980s error correction models describe the mechanism of adjustment to long run equilibrium

stocks flows and some exchange rate dynamics for the currency substitution model abstract the paper argues that the treatment of stocks and flows in portfolio balance models of exchange rate determination is inadequate and that this hampers the analysis of exchange rate dynamics a proposed resolution is reworked into the currency substitution model in addition to providing explicit solutions for the spot rate of exchange depreciation under different expectational hypotheses an attempt is made to clarify the dynamic properties of the model inter alia it is shown how exchange rate overshooting is possible without having to assume market frictions how a deteriorating current account deficit can coexist with an appreciating exchange rate and more generally how portfolio induced jumps in the exchange rate are linked to balance of payments flow influences on the evolution of the exchange rate

bank risk within and across equilibria abstract the global financial crisis highlighted that the financial system can be most vulnerable when it seems most stable this paper models non linear dynamics in banking small shocks can lead from an equilibrium with few bank defaults straight to a full freeze the mechanism is based on amplification between adverse selection on banks funding market and moral hazard in bank monitoring our results imply trade offs between regulators microprudential desire to shield individual weak banks and the macroprudential consequences of doing so moreover limiting bank reliance on wholesale funding always reduces systemic risk but limiting the correlation between bank portfolios does not

exchange rate models and innovations abstract an explicit relationship between innovations in the spot exchange rate and innovations in its driving variables is derived in the context of the asset market theory of the exchange rate the relationship forms a theoretical basis for regression results in news form that have been reported in the literature

the speculative efficiency hypothesis the hypothesis that forward prices are the best unbiased forecast of future spot prices is often presented in the economic and financial analysis of futures markets this paper considers the hypothesis independently of its implications for rational expectations or market efficiency and in order to stress this fact the term speculative efficiency is used to characterize the state envisaged under the hypothesis if a market is subject to efficient speculation the supply of speculative funds is infinitely elastic at the forward price that is equal to the expected future spot price the expected future spot price is a market price determined as the solution to the underlying rational expectations macroeconomic model although the paper is primarily concerned with testing this hypothesis in the foreign exchange market the methodology introduced in the paper is of general application to all futures markets this abstract was borrowed from another version of this item

determinants of economic well being among u s farm operator households participation in government programs has a mild impact on the economic well being of u s farm households major factors that determine farm household prosperity are the primary operator s education level and ethnicity education level of the spouse and other characteristics such as forward purchasing of inputs use of contract shipping of products having a succession plan farm ownership and location in a metro area this article uses the 2001 agricultural resource management survey arms as well as relative and an absolute measure to assess u s farm households economic well being the relative measure compares the income and wealth position of farm households relative to median income and median wealth of the general population the absolute measure adds annualized wealth to a farm household s income

testing for news in foreign exchange markets abstract traditional tests of the role of interest rate news on foreign exchange rates are analysed and found to be of little empirical value

news shocks in the data olympic games and their macroeconomic effects we examine the macroeconomic effects of bidding for the olympic games using panel data for 188 countries during the period 1950 2009 our findings confirm that economies react to news shocks investment consumption and output significantly increase 9 to 7 years before the actual event in bidding countries hosting countries also experience significant increases in investment consumption and output 5 to 2 years before the hosting of the games mapping the olympics into a macroeconomic model we show that we can match our empirical findings if we assume that an olympic bid represents news about increases in government investment

us money announcements and covered interest parity the case of japan abstract this paper examines the effects of us money announcements on dollar and yen denominated securities in their respective onshore markets the effects are consdered over several periods corresponding to possible us and japanese policy regimes the consistency of the responses is further examined by testing whether the responses of dollar denominated securities yen denominated securities the spot yen dollar exchange rate and the forward yen dollar exchange rate violate covered interest parity given the results of previous studies the evidence suggests that restrictions on capital mobility in japan have not allowed complete international integration of japanese financial markets

real exchange rate behavior abstract using random simulations with artificial data with identical sample characteristics to the long sample exchange rate data employed by lothian and taylor lothian j r and taylor m p 1996 the recent float from the perspective of the past two centuries journal of political economy 104 488 509 we show that standard unit root tests have extremely low power over sample sizes corresponding to the recent float the probability of rejecting the null hypothesis when it is false is extremely low with 20 years or even 50 years of data and only reaches an acceptable level over much longer spans

an empirical examination of long run purchasing power parity as theory of international commodity arbitrage an empirical analysis of long run purchasing power parity ppp as a theory of international commodity arbitrage between uk and us prices and the sterling us dollar exchange rate for the period 1975 1980 is presented econometric techniques concerning the cointegration of economic time series are applied to a sample of 35 manufactured commodities which in 1977 constituted approximately a quarter of the net output of all manufacturing industry in great britain our results are extremely unfavourable to the ppp hypothesis as a stable long run proportionality between exchange rates and disaggregated prices

uncertain liquidity and interbank contracting we study a version of the diamond and dybvig journal of political economy 1983 91 401 419 model where banks would like to obtain insurance against shocks on returns on liquid assets through an interbank borrowing and lending program we show that if investments in liquid assets and their realized returns are private information to individual banks the first best allocation is not incentive compatible we then characterize the second best interbank contract

exchange rates and news a multi currency approach abstract in this paper a multi currency model is used to investigate the relationship between spot exchange rates forward rates market efficiency and new information it is shown that in a world with more than two countries the error term in the standard market efficiency tests will be correlated across rates it is also shown that the exchange rate can be expressed as a function of factors known in advance which are captured by the forward rate determined in the previous period and news the empirical results presented in the paper tend to support the model s implications

a note on the determinants of unexpected exchange rate movements abstract in this paper we study the relative importance of surprises in fundamentals in explaining unexpected exchange rate movements employing a unique survey dataset that contains matched exchange rate and interest rate expectations we are able to derive a number of interesting conclusions a variance decomposition of unexpected exchange rate movements into various components reveals that interest rate news is relatively unimportant but that changes in perceptions about risk premia and more importantly revisions of expectations with regard to future exchange rate levels are crucial in explaining unexpected exchange rate movements

global growth opportunities and market integration we propose an exogenous measure of a country s growth opportunities by interacting the country s local industry mix with global price to earnings pe ratios we find that these exogenous growth opportunities predict future changes in real gdp and investment in a large panel of countries this relation is strongest in countries that have liberalized their capital accounts equity markets and banking systems we also find that financial development external finance dependence and investor protection measures are much less important in aligning growth opportunities with growth than is capital market openness finally we formulate new tests of market integration and segmentation by linking local and global pe ratios to relative economic growth in a perfectly integrated world economy capital should be invested where it

balance of trade announcements and movements in exchange rates there is a growing literature on the effect of economic news on foreign exchange rates the effects of weekly money supply announcements on exchange rates have been empirically investigated by a number of researchers over a variety of periods 1 2 3 4 7 11 12 13 the response of foreign exchange rates to other types of economic information has also been studied for example dornbusch 5 uses innovations in the current account cyclical factors and interest rates frenkel 10 uses innovations in interest rate differentials edwards 6 uses innovations in money real output and real interest rates most recently hardouvelis 14 studies the market response of three interest rates and seven exchange rates to economic news on fifteen economic aggregates including monetary announcements inflation rate announcements and announcements reflecting the stage of the business cycle this paper studies short run movements in foreign exchange rates to the commerce department s monthly announcements of the u s balance of merchandise trade it extends previous studies of foreign exchange response to economic news in three ways first by studying the response to the trade announcement which occurs two months after the month to which the announcement refers the paper provides a more precise measure of the response to the news content of trade related announcements than earlier studies this for instance is an improvement over dornbusch s 5 definition of current account news as the innovation in the actual oecd organization for economic co operation and development biannual current account estimates second the paper studies not only movements in spot rates to the announcement but calculates the movements in forward premiums to this information by studying the response in forward premiums to the merchandise trade announcements the paper examines whether the information in the announcements implies effects that operate through capital flows and interest rates in addition to responses that operate through the flow of merchandise trade

variance ratio tests of random walk for foreign exchange rates abstract the paper presents variance ratio tests of the random walk hypothesis for foreign exchange rates the data correspond to weekly exchange rates for four foreign currencies british pound german mark japanese yen and swiss franc it is found that the series contain large permanent component and small temporary component which suggests that exchange rates follow a random walk

import pricing and the trade balance in a popular model of exchange rate determination abstract this paper extends a popular model of exchange rate determination to include an import pricing relationship that is consistenc with imperfect competition in the importable sector the analysis highlights how import pricing behavior and aggregate macroeconomic relationships interact in determining the dynamics of the exchange rate the price of imports and the trade balance a basic prediction of the analysis is that an increase in the substitutability of imported product varieties in the domestic market will raise the responsiveness of the exchange rate and dampen the responsiveness of the trade account to monetary shocks

post bretton woods deviations from purchasing power parity in g7 exchange rates an empirical exploration abstract exchange rates have deviated substantially and idiosyncratically from purchasing power parity ppp since the breakdown of bretton woods in this paper a model incorporating both traditional ppp and financial market variables is constructed and tested on the us dollar s six g7 exchange rates during the floating rate era empirical tests show that the model s common set of variables with consistent signs can explain the divergent behavior of g7 exchange rates during 1973 2 90 2 idiosyncracies are reflected in different subsets of the model s variables entering significantly into each exchange rate s regression the existence of stable relationships is demonstrated by the equations co integration

a model of speculative efficiency with news error components this paper proposes a theoritical model to assess of news on the spot forward exchange rate relationship and thereby predicts of the impact of news on the exchange rate two types of news are analysed rational expectations type innovations and announcement effects form newspapers by using historical data form a time period which includes the german hyperinflation of the early 1920s an estimate from of the model is derived which is substantially simpler than the version requried using contemporary data preliminary results support the main theoretical predictions but also cast some doubt on a literal interpretation of the exchange rate model plus rational expectations

empirical determinants of purchasing power parity deviations abstract this paper investigates the empirical determinants of purchasing power parity ppp deviations over the recent period of flexible exchange rates transitory ppp deviations arise in a world in which prices are sticky but where exchange rates respond instantaneously to news permanent ppp deviations occur when price indices differ across countries and the world is subject to real shocks regressions consistent with the hypothesis that current exchange rate changes create immediate ppp deviations which are slowly dissipated but not eliminated imply that both sticky prices and real shocks are responsible for the recent failure of ppp

differential human capital and structural evolution in agriculture abstract the growth of market capitalism and the technological advances of the last two centuries underlie the relentless process of structural change in agriculture substantial occupational migration out of farming and geographical migration from rural to urban areas is a characteristic of most if not all economies in the 20th century the process of rural urban migration and the resulting urban problems have received considerable attention the fate of the residual farm population has received less scrutiny and is less well understood in the united states we observe considerable farm poverty increasing farm size inequality and a disturbing decay of rural communities for the last half century the problem of low farm incomes has been perceived as a farm problem amenable to solutio by appropriate farm policy in this paper a model is proposed which suggests that farm poverty and inequality are inevitable consequences of a rural urban migration process in which two types of human capital play a fundamental role general human capital determines a person s expected nonfarm income while farming specific human capital determines his her productivity in farming it is argued that inadequate human capital combined with positive rural urban migration cost positive farm technology adoption costs and inelastic demand for farm output can explain persistently high levels of farm poverty and increasing farm size inequality the model suggests that traditional farm policies are inappropriate programs that directly address the problems of inadequate human capital are advocated

the j curve effect and us agricultural and industrial trade this paper examines the j curve hypothesis for us agricultural and manufactured goods using the shiller lag model the results support the j curve effect for agricultural goods but not for manufactured goods these findings explain why many studies in the literature fail to support the j curve phenomenon there are two explanations for these findings 1 the aggregation bias of data that combine both agricultural and manufactured goods and 2 the country under study is often an industrial nation like the us or japan with a high proportion of manufactured goods in both exports and imports

money supply announcements interest rates and foreign exchange abstract this paper presents a test of the joint hypothesis that money supply announcements affect the real interest rate and that changes in the real interest rate affect the exchange rate in the short run the test results are consistent with the joint hypothesis for example it is found that announcement of an unexpected jump in the money supply is accompanied by an increase in interest rates and an appreciation of the dollar if the rise in interest rates was entirely due to higher inflationary expectations the dollar should not appreciate

creditor concentration an empirical investigation most of the literature on multiple banking assumes equal financing shares however unequal asymmetric or concentrated bank borrowing is widespread and creditor concentration is only weakly correlated with the number of bank relationships this paper therefore investigates the determinants of creditor concentration for german firms using a comprehensive firm bank level dataset for the time period between 1993 and 2003 we document that corporate borrowing from banks is very often concentrated even for the largest firms in our sample leveraged firms and firms with more redeployable assets concentrate their borrowing from banks as are firms dealing with a relationship lender that is profitable that has lower monitoring costs or that operates in a concentrated regional lending market

arbitrage cointegration and testing the unbiasedness hypothesis in financial markets we use a no arbitrage cost of carry asset pricing model to show that the existence of coin tegration between spot and forward futures prices depends on the time series properties of the cost of carry we argue that the conditions for cointegration are more likely to hold in currency markets than in commodity markets explaining many of the empirical results in the literature we also use this model to demonstrate why the forward rate forecast error the basis and the forward premium are serially correlated and to develop econometric tests ofthe unbiasedness hypothesis sometimes called the simple efficiency hypothesis in various financial markets the unbiasedness hypothesis is so prevalent in the finance liter ature that many tests for it have been developed we examine four of the common tests and and use our cointegration results to demonstrate why each of these tests should reject the null hypothesis of unbiasedness we find strong support for our hypothesis in the existing empirical literature

financial globalization and real regionalization over the period 1972 1986 the correlations of gdp employment and investment between the united states and an aggregate of europe canada and japan were respectively 0 76 0 66 and 0 63 for the period 1986 to 2000 the same correlations were much lower 0 26 0 03 and 0 07 real regionalization at the same time u s international asset trade has significantly increased for example between 1972 and 1999 united states gross fdi and equity assets in the same group of countries rose from 4 to 23 percent of the u s capital stock financial globalization we argue that these two trends are intimately related we document that the correlation of real shocks between the u s and the rest of the world has declined we then present a model in which international financial market integration occurs endogenously in response to less correlated shocks financial integration further reduces the international correlations in gdp and factor supplies we find that both less correlated shocks and endogenous financial market development are needed to account for all the changes in the international business cycle

the monetary exchange rate model as a long run phenomenon abstract pure time series based tests fail to find empirical support for monetary exchange rate models in this paper we apply pooled time series estimation on a forward looking monetary model resulting in parameter estimates which are in compliance with the underlying theory based on a panel version of the engle and granger engle r f granger c w j 1987 co integration and error correction representation estimation and testing econometrica 55 251 276 two step procedure we find that the residuals of the panel based estimated monetary model are stationary this indicates that on a pooled time series level there is cointegration between the exchange rate and the macroeconomic fundamentals of this monetary model

exchange rate models and exchange rate expectations an empirical investigation a non parametrictest of popular modern exchange rate models under alternative expectation specifications is presented it is found that there is little difference in the predictive success of the alternative exchange rate models however there are significant differences in the performance of a model depending upon the expectations mechanism specified our most important finding is that the flexible price monetary model the portfolio balance model and a hybrid model under extrapolative and adaptive expectations mechanisms provide statistically significant information about the direction of exchange rate movements by contrast the same models when employing static regressive and rational expectation mechanisms do not provideany satistically significant information

growth volatility and financial liberalization we examine the effects of both equity market liberalization and capital account openness on real consumption growth variability we show that financial liberalization is mostly associated with lower consumption growth volatility our results are robust surviving controls for business cycle effects economic and financial development the quality of institutions and other variables countries that have more open capital accounts experience a greater reduction in consumption growth volatility after equity market openings we also find that financial liberalizations are associated with declines in the ratio of consumption growth volatility to gdp growth volatility suggesting improved risk sharing our results are weaker for liberalizing emerging markets but we never observe a significant increase in real volatility moreover we demonstrate significant differences in the volatility response depending on the size of the banking and government sectors and certain institutional factors

minute by minute efficiency normality and randomness in intra daily asset prices in this study we test the efficiency of asset markets at intervals as short as 30 seconds we also describe the properties of a simple new stochastic process as a potential model of the behaviour of asset prices and test it on intra daily deutsche mark futures prices according to this process asset prices are constant between economically relevant events which occur at the random times generated by a poisson process at the moments of these events prices jump to new values the size of the jump is drawn from a normal distribution tests of this process indicate that it cannot be rejected for most of the days in the sample

currency crises capital account liberalization and selection bias are countries with unregulated capital flows more vulnerable to currency crises efforts to answer this question properly must control for self selection bias since countries with liberalized capital accounts may also have more sound economic policies and institutions that make them less likely to experience crises we employ a matching and propensity score methodology to address this issue in a panel analysis of developing countries our results suggest that after controlling for sample selection bias countries with liberalized capital accounts experience a lower likelihood of currency crises that is when two countries have the same likelihood of allowing free movement of capital based on historical evidence and a very similar set of economic and political characteristics and one country imposes controls and the other does not the country without controls has a lower likelihood of experiencing a currency crisis this result is at odds with the conventional wisdom and suggests that the benefits of capital market liberalization for external stability are substantial

human capital adaptive ability and the distributional implications of agricultural policy the ability to adapt efficiently to an economic environment that has been altered in a specific way may be a scarce resource in agriculture schultz 1 the setting that i wish to focus upon is one in which farmers face uncertainty about the future course of events production technologies prices and governmental policies and production is dynamic a large share of inputs is purchased from the nonfarm sector and a significant share of output is exported information is available on past realizations of events storing and analyzing information is costly consequently farmers are not assumed to have complete information farmers are assumed to differ in their adaptive ability which is viewed as a form of human capital and to employ efficiently the information that they acquire the thesis of this paper is that adaptive ability is unimportant when the processes generating the variables which farmers take as exogenous are stationary and unaltered however when these processes undergo structural change adaptive ability is expected to affect the quality of production marketing and investment decisions farmers who have superior adaptive skills are expected on average to make better decisions furthermore given the highly competitive nature of u s agriculture successfully adapting to structural change is selective farmers possessing poor adaptive skill can be expected to comprise a relatively large share of the persons forced by economic circumstances to seek alternative employment or retirement provided governmental intervention does not neutralize this selection process when farmers make production marketing and investment plans their decision rules can be expected to incorporate the anticipated values of uncertain variables that are exogeous to their choices the unanticipated components of these exogenous variables however may confuse them and reduce the efficiency of otherwise good plans 2 when shocks occur because of domestic or foreign macroeconomic policy u s agriculture is saddled with transmitting business cycle disturbances

financial fragility liquidity and asset prices we define a financial system to be fragile if small shocks have disproportionately large effects in a model of financial intermediation we show that small shocks to the demand for liquidity cause either high asset price volatility or bank defaults or both furthermore as the liquidity shocks become vanishingly small the asset price volatility is bounded away from zero in the limit economy with no shocks there are many equilibria however the only equilibria that are robust to the introduction of small liquidity shocks are those with non trivial sunspot activity

the impact of monetary regime changes some exchange rate evidence abstract lucas has argued that coefficient changes can be explained by changing expectations caused by the policy regime shifts this paper provides evidence consistent with the lucas critique using an efficient markets news framework kalman filter results show that surprise relative u s monetary expansion is associated both with periods of u s depreciation and appreciation i show that variables representing changes in monetary policy regimes can explain a substantial fraction of the movements in the time varying parameter

syndicated euro credit sovereign risk assessments market efficiency and contagion effects this study investigates the informational efficiency of the syndicated euro credit market by analyzing the adjustment of spreads to news characterizing the state of sovereign borrowers creditworthiness in addition the potential for an interlinked crisis contagion effects between three major borrowing countries is examined that is contagion tests are conducted to see how news for one borrower affects the spreads charged to the others the evidence suggests that the euro credit pricing process has been informationally efficient however with respect to the contagion effects it was found that noncountry specific risk factors systematically influence country specific spreads

exchange rate based stabilization in latin america abstract this paper examines the use of the exchange rate as a nominal anchor for achieving price stability in latin america it will explore the impact of exchange rate anchoring on the real sector by analyzing five stabilization programs the paper will identify conditions that make exchange rate based stabilization successful and those that lead to its failure it will also demonstrate that while the income effect can be instrumental in describing consumption booms associated with exchange rate based stabilizations the popular view based on the credibility hypothesis fails to explain key events associated with such programs

flexible exchange rates prices and the role of news lessons from the 1970s recent experience with flexible exchange rate systems has led to renewed interest in the operation of foreign exchange markets as reflected in many recent studies of the principal determinants of exchange rates the 1970s witnessed the dramatic alteration of the international monetary system from a regime of pegged exchange rates which prevailed for about a quarter of a century since the bretton woods conference into a regime of flexible though managed rates as a consequence of the emergence of the new legal and economic system traders national governments and international organisations were confronted with new economic problems choices and instruments during the 1970s ex change rates fluctuated widely and inflation rates accelerated the international monetary system had to accommodate extraordinarily large oil related shocks which affected trade flows in goods and assets huge oil payments had to be recycled uncertainties concerning future developments in international politics reached new heights and the prospects for the world economy got gloomier these developments placed unprecedented pressures on the markets for foreign exchange as well as on other asset markets they were associated with a large slide in the value of the us dollar and resulted in speeding up the creation of new institutions like the european monetary system which provided the formal framework for the management of exchange rates among members

on jump processes in the foreign exchange and stock markets exchange rates exhibit systematic discontinuities even after allowingfor conditional heteroskedasticity in the diffusion process the results are much more significant in theforeign exchange market than in the stock market which suggests differences in the structure of these markets finally this jump component is shown to explain some of the empirically observed mispricings in the currency options market the objective of this article is to analyze and compare the empirical distribution of returns in the stock market and in the foreign exchange market there are a number of reasons why a better understanding of the stochastic processes driving prices in these markets would be useful many financial models rely heavily on the assumption of a particular stochastic process while relatively little attention is paid to the empirical fit of the postulated distribution as a result models like option pricing models are applied indiscriminately to various markets such as the stock market and the foreign exchange market when the underlying processes may be fundamentally different the foreign exchange market for instance is characterized by active exchange rate man

the cost of a central bank leaning against a random walk abstract using a stochastic model we show that a central bank is expected to suffer a loss when it temporarily affects the exchange rate by sterilized intervention against a random walk we also demonstrate that the methodology used in several studies of the profitability of official central bank intervention biases their results towards finding positive profits this bias created by only observing periods where cumulative intervention sums to zero accounts for the seemingly contradictory empirical results of several intervention profitability studies

inflation news and exchange rates abstract this paper presents a new test of the purchasing parity theory by investigating the announcement effect of unexpected inflation on the exchange rate of the us dollar against three european currencies the evidence presented does not support the theory at least in the very short run

the ecu as international money abstract the ecu is compared with alternative foreign currencies to determine how adequately it performs the various functions of international money for the period april 1979 through december 1984 it is found that for most european economic agents the ecu was superior to the sdr the us dollar and a representative foreign currency the netherlands guilder as a unit of account as a store of value and as a means of deferred payment an examination is made of the distribution of the series of exchange rate changes so that appropriate statistical methods are employed in making a final assessment about the variability of the ecu

the political economy of development a cross national causality test of development democracy growth hypothesis the empirical investigation of the development democracy growth hypothesis estimates positive correlations and causal associations between development and democracy and democracy and growth among the preconditions for the emergence of democracy market and culture show strong and highly significant positive effects which are largely transmitted directly development affects democracy directly and indirectly via education and investment the positive causal association between democracy and growth is transmitted both directly and indirectly via labor and welfare accordingly the hypothesized compatibility between economic development and political democracy is confirmed while rejecting the trade off between political democracy and economic growth

measuring european financial integration in this paper we present a set of specific measures to quantify the state and evolution of financial integration in the euro area five key markets are considered namely the money corporate bond government bond credit and equity markets building upon the law of one price we have developed two types of indicators that can be broadly categorized as price based and news based measures we have complemented these measures by a number of quantity based indicators mainly related to the evolution of the home bias results indicate that the unsecured money market is fully integrated while integration is reasonably high in the government and corporate bond markets as well as in the equity markets the credit market is among the least integrated especially in the short term segment

a panel project on purchasing power parity mean reversion within and between countries abstract previous time series studies have shown evidence of mean reversion in real exchange rates deviations from purchasing power parity ppp appear to have half lives of approximately four years however the long samples required for statistical significance are unavailable for most currencies and are potentially inappropriate because of regime changes in this study we re examine deviations from ppp using a panel of 150 countries and 45 annual post wwii observations our panel shows strong evidence of mean reversion that is similar to that from long time series ppp deviations are eroded at a rate of approximately 15 annually i e their half life is around four years such findings can be masked in time series data but are relatively easy to find in cross sections

financial integration specialization and systemic risk this paper studies the implications of cross border financial integration for financial stability when banks loan portfolios adjust endogenously banks can be subject to sectoral and aggregate domestic shocks after integration they can share these risks in a complete interbank market when banks have a comparative advantage in providing credit to certain industries financial integration may induce banks to specialize in lending an enhanced concentration in lending does not necessarily increase risk because a well functioning interbank market allows to achieve the necessary diversification this greater need for risk sharing though increases the risk of cross border contagion and the likelihood of widespread banking crises however even though integration increases the risk of contagion it improves welfare if it permits banks to realize specialization benefits

beyond the purchasing power parity testing for cointegration and causality between exchange rates prices and interest rates abstract this paper reexamines the causality between the dollar and the yen in a multivariate framework with the aid of cointegration and error correcting modeling for the 1951 94 period the phillips perron tests and johansen s tests are performed while causality from interest rates to exchange rates is found in the short run no causality between prices and exchange rates is found in the short run however causality is found running from relative prices to exchange rates along with interest rates between the u s and japan in the long run which supports the long run ppp hypothesis

the distribution of income and wealth of farm operator households because of the relatively low incomes of people associated with farming in the past income maintenance has been a major focus of farm policy the average money income of families earning farm self employment income in 1983 was 93 of the average money income of other u s families usdc however an average income of farm households has lost much of its meaning because it masks a great deal of variation compared to the past farm households represent a heterogenous population presenting a new challenge to policy makers concerned about framing income maintenance policies the current farm bill debate began in 1984 amidst piecemeal information on increased bankruptcies and general financial stress of farms analysis of the financial leverage and cash flow positions of farm businesses has since been forthcoming johnson baum and prescott however information on the financial well being of those households associated with farming has remained limited the purpose of this paper is to describe the financial well being of farm operator households by measuring their size distribution of personal income and farm equity in 1984 the contribution of each source of income to the total inequality of incomes is also analyzed

is there a relationship between economic conditions and political structure the results of this investigation into the relationship between political environment and economic well being are both disappointing and encouraging phone is the only measure of economic well being which is unambiguously and positively associated with democracies why this is true remains a mystery the two reasons discussed earlier are both plausible as in a third namely increasing availability of telephones reduces the costs of organizing special interest groups to the extent that active participation of special interests is a necessary condition for the emergence or continuation of democratic government telephones per capita will be related positively to the incidence of democracy

returns to education under collective and household farming in china abstract this paper presents a theoretical model and shows that greater distributional equality decreases individuals returns to education the evidence from a production team in 1977 and the rural household farming in 1990 both in china lends support for the model production team did not reward most members especially for those with higher work points such as the married and males education during most of their lifetimes in distributing work points and labor income however under the household farming system a household s average or highest educational level increased its net agricultural income and total efficiency labor for all households at any average highest educational and age levels thus our findings support the idea that reaping returns from schooling investments requires appropriate economic political environments

political systems and distortions an empirical study this paper studies empirically why price distortions are more prevalent in some countries than in others we find no significant difference between democracies and dictatorships but frequent regime changes reduce distortions political systems factional subordinate that encourage redistributive activities rda tend to have more distortions allowing for different effects of rda in democracies and dictatorships there is a positive and significant effect of rda on distortions in dictatorships in democracies distortions destroying lobbying seems more important since no significant relation between rda and distortions can be found

forward implications of a simple stochastic asset market model abstract the behavior of forward rates in a simple stochastic asset market model is investigated theoretically empirical estimates from the foreign exchanges show the model to be of relevance

liquidity shortages and banking crises we show in this article that bank failures can be contagious unlike earlier work where contagion stems from depositor panics or contractual links between banks we argue that bank failures can shrink the common pool of liquidity creating or exacerbating aggregate liquidity shortages this could lead to a contagion of failures and a total meltdown of the system given the costs of a meltdown there is a possible role for government intervention unfortunately liquidity and solvency problems interact and can cause each other making it hard to determine the cause of a crisis we propose a robust sequence of intervention banks are often found at the center of systemic financial crises the causes of these crises have long been debated do they stem from depositor panics or do they arise because bank balance sheets are exposed to common factors if it is the latter then is there any sense in which bank failures can be contagious can anything be done to prevent these crises or stop them from propagating once they begin our purpose in this paper is to reexamine whether bank failures can start and propagate systemic crises even if we assume that depositors do not panic that is even if depositors actions are coordinated and they do not run simply because they fear others will run our focus is not because we think that panics are empirically unimportant the jury is still out on that instead we show that contagion can stem from an underlying real general equilibrium problem rather than just from lack of coordination among depositors from a policy perspective attempts to reassure investors through confidence building measures will not work if panic and lack of coordination are not the reasons for a crisis we begin in this paper with a model of a bank that we developed in diamond and rajan 2001 assets in this model are illiquid they cannot be borrowed against or sold for the full value of resources they will generate in their best use because the human capital necessary to generate that full value cannot

interbank lending and systemic risk systemic risk refers to the propagation of a bank s economic distress to other economic agents linked to that bank through financial transactions banking authorities often prevent systemic risk through an implicit insurance of interbank claims or by reducing interbank transactions and centralizing banks liquidity management this paper investigates whether the flexability afforded by decentralized bank interactions can be preserved while protecting the central banks from the necessity of conducting undesired rescue operations it develops a model in which decentralized interbank leading is motivated by peer monitoring in this context the paper derives the optimal prudential rules and in particular looks at the impact of interbank monitoring on the solvency and liquidity ratios of borrowing and lending banks last it provides conditions which a too big to fail policy is or is not justified and studies the possibility of propagation of a bank s liquidity shock throughout the financial system copyright 1996 by ohio state university press

risk sharing and industrial specialization regional and international evidence the authors provide empirical evidence that risk sharing enhances specialization in production to the best of their knowledge this well established and important theoretical proposition has not been tested before the empirical procedure is summarized as follows first the authors construct a measure of specialization in production and calculate an index of specialization for each of the european community ec and non ec oecd countries u s states canadian provinces japanese prefectures latin american countries and regions of italy spain and the united kingdom then they estimate the degree of capital market integration a measure of risk sharing within each of these groups of regions the ec countries the non ec oecd countries the united states canada japan italy spain and the united kingdom and rely on another author s estimate for latin america finally they perform a regression of the specialization index on the degree of risk sharing controlling for relevant economic variables they find a positive and significant relation between the degree of specialization of individual members of a group of countries provinces states or prefectures and the amount of risk that is shared within the group the authors perform regressions using variables such as shareholder rights and the size of the financial sector relative to gdp as instruments for the amount of inter regional risk sharing these regressions confirm that risk sharing facilitated by a favorable legal environment and a developed financial system is a direct causal determinant of industrial specialization this abstract was borrowed from another version of this item

searching for stationarity purchasing power parity under the current float abstract using panel data methods we investigate long run purchasing power parity by testing for unit roots in real exchange rates of industrial countries under the current float the evidence against the unit root hypothesis is stronger for larger than for smaller panels for monthly than for quarterly data and when the german mark rather than the united states dollar is used as the base currency while we find that accounting for serial correlation considerably weakens the evidence against the unit root null the results as a whole are consistent with long run purchasing power parity

european financial market dependence an industry analysis this paper uses a copula model to investigate the degree and determinants of european market dependence across 10 industries in 12 euro zone and 8 non euro zone stock markets during the period 1992 2011 most of the industries in euro countries show a dependence increase with the euro area after the introduction of the euro the effects are strongest in countries with larger market capitalization and in the financials industrials consumer goods utilities technology and telecommunications industries overall the export intensity interest rate sensitivity and competitiveness of an industry and the financial development and economic openness of a country are the most important determinants of changes in equity market dependence the period around the lehman collapse also shows higher equity market dependence between european countries while the lower dependence increase during the period of the recent european sovereign debt crisis suggests that country specific factors may matter more than before

understanding the empirical literature on purchasing power parity the post bretton woods era abstract this paper argues that the empirical failure of statistical tests of ppp in post bretton woods data is largely due to the low power of the tests employed this result is demonstrated using monte carlo experiments on the size and power of different testing procedures a new procedure based on horvath and watson econometric theory 11 pp 984 1014 1995 has greater power than previous approaches using the horvath watson procedure we find moderate evidence in favor of ppp in the post bretton woods era

financial integration productivity and capital accumulation understanding the mechanism through which nancial globalization aects eco nomic performance is crucial for evaluating the costs and bene ts of opening nancial markets this paper is a rst attempt at disentangling the eects of nancial inte gration on the two main determinants of economic performance productivity tfp and investment i provide empirical evidence from a sample of 70 countries observed between 1975 and 1999 the results for both de jure and de facto indicators suggest that nancial integration has a positive direct eect on productivity while it does not directly aect capital accumulation i also control for indirect eects of nancial globalization through nancial development and banking and currency crises while nancial integration does not systematically increase domestic nancial depth it may raise the likelyhood of banking crises though only to a minor extent yet the overall eect of nancial liberalization remains positive for productivity and negligible for investment
