a perspective on the symptoms and causes of the financial crisis abstract prior to the 2007 2008 financial crisis banking sector profits were very high but the profitability of financial intermediation was poor using a novel model of banking this article argues that the high profits were achieved through balance sheet expansion and growing default liquidity and term risk mismatches between assets and liabilities as a result large banks financial leverage rose as they became less liquid setting the conditions for a systemic banking crisis this article argues that the increase in financial leverage was possible due to misguided changes in the regulatory framework specifically the basel i capital accord and reductions in reserve requirements finally this article overviews and assesses the policy response in the aftermath of the crisis

u s comparative advantage in bioenergy a heckscher ohlin ricardian approach much of the current literature on trade in biofuels is focused on the partial equilibrium welfare effects in the u s ethanol sector of potentially distorting policy instruments such as tax credits to blenders and import tariffs see elobeid and tokgoz 2006 de gorter and just 2007 however recent studies by the oecd 2006 and the world bank kojima mitchell and ward 2007 have expanded the analysis to consider the future prospects for trade in both ethanol and biodiesel paying particular attention to current production costs across countries and the connection between thresh old prices for crude oil prices and biofuel pro duction costs as well as the land requirements needed to meet the types of biofuel production mandates being implemented in the united states the european union eu and else where two key stylized facts can be gleaned from these latter studies while increasing crude oil prices have improved the economic viability of say u s corn based ethanol brazil continues to have a significant comparative advantage in producing ethanol from sugarcane oecd 2006 kojima mitchell and ward 2007 sec ond the land requirements necessary to meet targets being set for the proportion of biofu els used in transport fuel consumption show that again brazil has a clear comparative ad vantage for example brazil only requires 3 of its agricultural land to meet a 10 share of biofuels in domestic transport fuel consump tion compared to 30 36 and 72 re spectively in the united states canada and the e u oecd 2006 this all seems to point to a simple but rather predictable story of trade in biofuels in the absence of trade distorting policy instru ments brazil currently has a comparative and maybe even an absolute advantage in produc ing biofuels based on lower ethanol feedstock costs and relative abundance of agricultural land even in the presence of trade distortions brazil exported 20 of its production during the 2006 7 harvest season kojima mitchell and ward 2007 and this would increase sub stantially if the united states removed its ethanol import tariff of 54 cents per gallon elobeid and tokgoz 2006 however the mar gin for competitiveness in biofuels is rather narrow only 10 of production being traded internationally of which brazil accounts for 50 kojima mitchell and ward 2007 this is a static story though based on cur rent crop yields as well as existing biofuel production technologies consequently in try ing to analyze the potential for united states comparative advantage in biofuels production it is important to account for technological innovation that may occur within the next decade notably in the production of ethanol from cellulosic material to that end a styl ized trade model is set out in the first part of this article which allows for the possibil ity that the united states could become a fu ture exporter of biofuels the model draws on a heckscher ohlin ricardo approach origi nally due to davis 1995 as well as analysis of trade in the presence of external economies helpman and krugman 1985 given this analysis the second part of the article is con cerned with the possibility that current u s policy toward corn based ethanol production may actually stymie the potential for future exports drawing on recent literature analyz ing the infant industry argument for protec tion saure 2007

removal of u s ethanol domestic and trade distortions impact on u s and brazilian ethanol markets we analyze the impact of trade liberalization and removal of the federal tax credit in the united states on u s and brazilian ethanol markets using a multi market international ethanol model calibrated on 2005 market data and policies the removal of trade distortions induces a 23 2 percent increase in the price of world ethanol on average between 2006 and 2015 relative to the baseline the u s domestic ethanol price decreases by 14 1 percent which results in a 7 5 percent decline in production and a 3 2 percent increase in consumption the lower domestic price leads to a 2 5 percent rise in the share of fuel ethanol in gasoline consumption u s net ethanol imports increase by 192 8 percent brazil responds to the higher world ethanol price by increasing its production by 8 8 percent on average total ethanol consumption in brazil decreases by 3 2 percent and net exports increase by 61 9 percent relative to the baseline the higher ethanol price leads to a 4 7 percent increase in the share of sugarcane used in ethanol production the removal of trade distortions and 51 per gallon tax credit to refiners blending ethanol induces a 22 5 percent increase in the world ethanol price

structural causes of the global financial crisis a critical assessment of the new financial architecture we are in the midst of the worst financial crisis since the great depression this crisis is the latest phase of the evolution of financial markets under the radical financial deregulation process that began in the late 1970s this evolution has taken the form of cycles in which deregulation accompanied by rapid financial innovation stimulates powerful financial booms that end in crises governments respond to crises with bailouts that allow new expansions to begin as a result financial markets have become ever larger and financial crises have become more threatening to society which forces governments to enact ever larger bailouts this process culminated in the current global financial crisis which is so deeply rooted that even unprecedented interventions by affected governments have thus far failed to contain it in this paper we analyse the structural flaws in the financial system that helped bring on the current crisis and discuss prospects for financial reform

trade finance specialization and synchronization i investigate the determinants of business cycle synchronization across regions the linkages between trade in goods financial openness specialization and business cycle synchronization are evaluated in the context of a system of simultaneous equations the main results are as follows i specialization patterns have a sizable effect on business cycles most of this effect is independent of trade or financial policy but directly reflects differences in gdp per capita ii a variety of measures of financial integration suggest that economic regions with strong financial links are significantly more synchronized even though they also tend to be more specialized iii the estimated role of trade is closer to that implied by existing models once intra industry trade is held constant the results obtain in a variety of data sets measurement strategies and specifications they relate to a recent strand of international business cycle models with incomplete markets and transport costs and on the empir

do green tech policies need to pass the consumer test the case of ethanol fuel abstract this paper investigates a question sometimes overlooked by policymakers and regulators namely the need of a robust value proposition for green technologies to successfully enter the market in particular results from consumer choice models are used to develop measures of consumer acceptance of ethanol blends and flex fuel vehicles is studied a fuel vehicle system that has received attention in a variety of federal and state policies the analysis suggests that under projected fuel prices and given the characteristics of the competing vehicle fuel systems consumers are unlikely to substitute ethanol blends for gasoline the analysis also highlights the need for further research in this area

risk premium and market power in credit markets abstract the use of credit risk adjusted marginal opportunity cost of funds in the computation of the lerner index for bank loans opens new directions to properly evaluate market power of banks in credit markets beyond disputed concentration measures

market structure and the nature of price rigidity evidence from the market for consumer deposits panel data on consumer bank deposit interest rates reveal asymmetric impacts of market concentration on the dynamic adjustment of prices to shocks banks in concentrated markets are slower to raise interest rates on deposits in response to rising market interest rates but are faster to reduce them in response to declining market interest rates thus banks with market power skim off surplus on movements in both directions since deposit interest rates are inversely related to the price charged by banks for deposits the results suggest that downward price rigidity and upward price flexibility are a consequence of market concentration

import demand for brazilian ethanol a cross country analysis abstract this study presents an empirical analysis of the import demand for brazilian ethanol by its six major foreign buyers the primary objectives of this study were to identify the economic factors affecting the demand for ethanol imports and to derive long run price and income elasticities of import demand these elasticities could be used to analyze the impact of government policies such as mandatory gasoline ethanol blends and import tariffs import demand models were estimated with ordinary least squares ols using quarterly time series data for the 1997 2007 time period the results suggest that the factors influencing the import demand for ethanol vary across countries markets adopting mandatory blends of renewable fuels tend to have less price elastic import demand schedules ethanol imports were found to be price elastic and statistically significant in the caribbean region 1 66 mexico 2 08 japan 1 44 and nigeria 1 38 while import demand was price inelastic and not statistically different from zero in the us 0 76 and europe 0 21 the regression results could not determine the impacts of import tariffs for the united states mexico and nigeria on the quantity of imports because tariffs did not vary during the time period studied results show that mandatory gasoline ethanol blends have been an important determinant of ethanol imports

what s different about banks abstract negotiable certificates of deposit cd s trade in the capital market in competition with other securities like commercial paper and bankers acceptances if cd s must pay lenders competitive monetary interest the reserve tax on cd s is borne by bank borrowers viability of the tax means there must be something special about bank loans that makes some borrowers willing to pay higher interest rates than those on other securities of equivalent risk moreover there must be something special about banks that prevents other intermediaries from competing to assure that it never pays to finance loans with cd s

an asymmetry generator for error coorection mechanisms with application to bank mortgage rate dynamics empirical evidence supports asymmetries in the adjustment of prices interest rates and other economic variables the asymmetry hypothesis however is often procedurally difficult to set up and test this article shows that a wide variety of such mechanisms can be nested within an asymmetry generator which represents the interactions between the disequilibrium term of an error correction mechanism and an ancillary driver process the asymmetry hypothesis can then be tested in a straightforward extension of linear statistical methods the methods are applied to 10 years of monthly new zealand mortgage rate data

deposit spreads and the welfare cost of inflation abstract high nominal interest rates are associated with high deposit spreads which is consistent with a model where banks have monopoly power and currency and deposits are substitutes therefore higher interest rates raise the implicit price of banking services increase bank profits and attract entry into the banking sector taking these effects into account a one percentage point increase in inflation has a welfare cost of 0 083 of gdp 6 7 times higher than traditional estimates

the alcohol program the rational for the launching of the alcohol program from sugarcane in brazil in the mid 1970 s is described as an answer to the first oil crisis as well as a solution to the problem of the fluctuating sugar prices in the international market the technical characteristics of ethanol as a fuel are given as well as a discussion of the evolution of the cost of production environmental and social consequences regarding costs ethanol production was close to 100 dollars a barrel in the initial stages of the program in 1980 falling rapidly due to economies of scale and technological progress to half that value in 1990 followed by a slower decline in recent years considering the hard currency saved by avoiding oil importation through the significant displacement of gasoline by ethanol and the decrease in the amount of external debt that the displaced oil importation was able to provide it is possible to demonstrate that the alcohol program has been an efficient way of exchanging dollar debt by national currency subsidies which are paid by the liquid fossil fuel users even with this economic gains for society the continuity of the program is difficult to maintain two solutions to this problem are discussed internal expansion of the use of ethanol and exports to industrialized countries where it could be used as an octane enhancer the main attractiveness of the program the reduction of co2 emissions as compared to fossil fuels is stressed mainly as a solution for industrialized countries to fulfill their commitments with the united nations framework climate change convention

business cycles and monetary regimes in emerging economies a role for a monopolistic banking sector abstract this study shows that the presence of imperfect competition in the banking system propagates external shocks and amplifies the business cycle strategic limit pricing aimed at protecting retail niches from potential competitors generates countercyclical bank markups markup increments during recessions directly increase borrowing costs for firms and indirectly damage the financial position of firms balance sheets increasing the risk perception of lenders i use bayesian techniques and data from argentina to show that the inclusion of monopolistic banking improves the fit of the new keynesian small open economy model

capital requirements monetary policy and aggregate bank lending theory and empirical evidence capital requirements linked solely to credit risk are shown to increase equilibrium credit rationing and lower aggregate lending the model predicts that the bank s decision to lend will cause an abnormal runup in the borrower s stock price and that this reaction will be greater the more capital constrained the bank i provide empirical support for this prediction the model explains the recent inability of the federal reserve to stimulate bank lending by increasing the money supply i show that increasing the money supply can either raise or lower lending when capital requirements are linked only to credit risk the motivation of this article is first to examine the impact of risk based capital requirements namely those that link mandatory capital to asset ratios for banks to their loans on aggregate bank lending these requirements called the basle capital rules or bis guidelines went into effect in march 1989 for banks in the leading industrialized nations these rules initially required banks to maintain capital equal to 7 25 percent of business and most consumer loans with the requirement increasing to 8 percent by the end of 1992 secondly i wish to understand the link between monetary policy and aggregate bank credit in the presence of risk based capital requirements my curiosity is sparked in part by two recent phenomena one is the experience of the u s economy which displayed sluggish growth during 1989 93 despite a monetary policy that attempted to spur bank lending and economic activity and the other is the striking decline in loans relative to security holdings mostly government bonds in the asset portfolios of u s

is the 2007 u s sub prime financial crisis so different an international historical comparison the first major financial crisis of the twentyfirst century involves esoteric instruments unaware regulators and skittish investors it also follows a well trodden path laid down by centuries of financial folly is the special prob lem of sub prime mortgages really different our examination of the longer historical record which is part of a larger effort on cur rency and debt crises finds stunning qualitative and quantitative parallels across a number of standard financial crisis indicators to name a few the run up in us equity and housing prices that graciela l kaminsky and reinhart 1999 find to be the best leading indicators of crisis in countries experiencing large capital inflows closely tracks the average of the previous 18 post world war ii banking crises in industrial countries so too does the inverted v shape of real growth in the years prior to the crisis despite widespread concern about the effects on national debt of the tax cuts of the early 2000s the run up in us public debt is actually some what below the average of other crisis episodes in contrast the pattern of us current account deficits is markedly worse at this juncture the book is still open on how the current dislocations in the united states will play out the precedent found in the aftermath of other episodes suggests that the strains can be quite severe depending especially on the initial degree of trauma to the financial system and to some extent the policy response the average drop in real per capita output growth is over 2 percent and it typically takes two years to return to trend for the five most catastrophic cases which include episodes in finland japan

asymmetric adjustment of commercial bank interest rates evidence from malaysia and singapore abstract this paper examines the rigidity of commercial bank interest rates using evidence from singapore and malaysia an asymmetric error correction technique is used to test whether mean adjustment lags are different when retail rates are above or below their equilibrium levels it is concluded in both countries that the mean adjustment lag is shorter when the deposit rate is above its equilibrium than when it is below its equilibrium using the framework of hannan and berger 1991 this finding implies that the hypothesis of collusion cannot be rejected

international business cycles with endogenous incomplete markets backus kehoe and kydland 1992 baxter and crucini 1995 and stockman and tesar 1995 find two major discrepancies between standard international business cycle models with complete markets and the data in the models cross country correlations are much higher for consumption than for output while in the data the opposite is true and cross country correlations of employment and investment are negative while in the data they are positive this paper introduces a friction into a standard model that helps resolve these anomalies the friction is that international loans are imperfectly enforceable any country can renege on its debts and suffer the consequences for future borrowing to solve for equilibrium in this economy with endogenous incomplete markets the methods of marcet and marimon 1999 are extended incorporating the friction helps resolve the anomalies more than does exogenously restricting the assets that can be traded

emerging problems with the basel capital accord regulatory capital arbitrage and related issues in recent years securitization and other financial innovations have provided unprecedented opportunities for banks to reduce substantially their regulatory capital requirements with little or no corresponding reduction in their overall economic risks a process termed regulatory capital arbitrage these methods are used routinely to lower the eaective risk based capital requirements against certain portfolios to levels well below the basel capital accord s nominal 8 total risk based capital standard this paper discusses the principal techniques used to undertake capital arbitrage and the diaculties faced by bank supervisors in attempting to deal with these activities under the current capital framework 2000 elsevier science b v all rights reserved

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

a bank asset and liability management model in managing its assets and liabilities in light of uncertainties in cash flows cost of funds and return on investments a bank must determine its optimal trade off between risk return and liquidity in this paper we develop a multiperiod stochastic linear programming model alm that includes the essential institutional legal financial and bank related policy considerations and their uncertainties yet is computationally tractable for realistically sized problems a version of the model was developed for the vancouver city savings credit union for a 5 year planning period the results indicate that alm is theoretically and operationally superior to a corresponding deterministic linear programming model and that the effort required for the implementation of alm and its computational requirements are comparable to those of the deterministic model moreover the qualitative and quantitative characteristics of the solutions are sensitive to the model s stochastic elements such as the asymmetry of cash flow distributions we also compare alm with the stochastic decision tree sdt model developed by s p bradley and d b crane alm is computationally more tractable on realistically sized problems than sdt and simulation results indicate that alm generates superior policies

how does globalization affect the synchronization of business cycles this paper examines the impact of rising trade and financial integration on international business cycle comovement among a large group of industrial and developing countries the results provide at best limited support for the conventional wisdom that globalization has increased the degree of synchronization of business cycles the evidence that trade and financial integration enhance global spillovers of macroeconomic fluctuations is mostly limited to industrial countries one striking result is that on average cross country consumption correlations have not increased in the 1990s precisely when financial integration would have been expected to result in better risk sharing opportunities especially for developing countries this abstract was borrowed from another version of this item

a new database on the structure and development of the financial sector this article introduces a new database of indicators of financial structure and financial development across countries and over time the database is unique in that it combines a wide variety of indicators that measure the size activity and efficiency of financial intermediaries and markets it improves on previous efforts by presenting data on the public share of commercial banks introducing indicators of the size and activity of nonbank financial institutions and constructing measures of the size of bond and primary equity markets this article introduces a new database the first to provide comprehensive measures of the development structure and performance of the financial sector this database is the first to define and construct indicators of the size and activity of nonbank financial intermediaries such as insurance companies pension funds and non deposit money banks it is also the first to include indicators of the size of primary equity markets and primary and secondary bond markets in constructing the database authors carefully deflate measures and match stock and flow variables

market power in banking countercyclical margins and the international transmission of business cycles abstract by introducing an imperfectly competitive banking sector into a standard two country two good rbc model with complete asset markets we study the international transmission of aggregate tfp shocks in an environment with noncompetitive financial intermediation in this model price cost margins in a global loan market are endogenous and countercyclical as a result a positive tfp shock in one country spills over to another through a reduction in the global cost of both credit and externally financed investment the quantitative analysis shows that countercyclical margins on loans play a key role in bringing the predictions of the theory closer to the observed cross country cyclical co movements of consumption employment investment and output recessions are deeper when the cost of credit rises during these economic downturns thus a financial accelerator arises in our framework unveiling the increased importance of stabilization policies in economies where margins in credit markets are countercyclical

the deposits channel of monetary policy we propose and test a new channel for the transmission of monetary policy we show that when the fed funds rate increases banks widen the interest spreads they charge on deposits and deposits ow out of the banking system we present a model in which imperfect competition among banks gives rise to these relationships an increase in the nominal interest rate increases banks market power inducing them to increase deposit spreads and hence restrict deposit supply households respond to the increase in deposit prices by substituting from deposits into less liquid but higheryielding assets consequently changes in the nominal interest rate aect banks cost of capital and lending using branch level data on the universe of u s banks we show that following an increase in the fed funds rate deposit spreads increase by more and supply falls more in areas with less deposit competition we control for changes in banks lending opportunities by comparing branches of the same bank we control for changes in macroeconomic conditions by showing that deposit spreads widen immediately after a rate change and even if this change is fully anticipated our results imply that monetary policy has a signicant impact on how the nancial system is funded on the quantity of safe and liquid assets it produces and on its provision of loans to the real economy

determinants of business cycle comovement a robust analysis abstract this paper investigates the determinants of business cycle comovement between countries our dataset includes over 100 countries both developed and developing we search for variables that are robust in explaining comovement using the approach of leamer amer econom rev 73 1983 31 variables considered are i bilateral trade between countries ii total trade in each country iii sectoral structure iv similarity in export and import baskets v factor endowments and vi gravity variables we find that bilateral trade is robust however two variables that the literature has argued are important for business cycles industrial structure and currency unions are found not to be robust

credit cronyism and control evidence from the americas abstract i examine the effects of corruption and government control of the banking system for 18 western hemisphere countries on the sensitivity of commercial lending rates to changes in international financial conditions and find that most countries lending rates are insensitive to these conditions only the least corrupt nations exhibit a significant positive relation between lending rates and international financial conditions the responsiveness of these lending rates is nonlinearly related to corruption and government control of the banking sector the findings suggest that both corruption and government control of banks need to be considered when analyzing international credit markets

fairly priced deposit insurance and bank charter policy the thrust of current deposit insurance reform risk based insurance premiums and capital requirements is an effort to price deposit insurance more fairly fairly pricing deposit insurance eliminates inequitable wealth transfers but it does not lead to an efficient equilibrium this paper shows that an alternative charter policy results in an efflcient separating equilibrium this article analyzes the effect of alternative charter policies when deposit insurance is fairly priced the thrust of current deposit insurance reformrisk based capital requirements 1988 and risk based insurance premiums 1994 is an effort to price deposit insurance more fairly chan greenbaum and thakor s 1992 seminal paper dramatically illustrated that fairly pricing deposit insurance is not enough to solve the deposit insurance problem in their model when banks hold nontraded private information assets no equilibrium exists with fairly priced deposit insurance unless banks earn rent or are subsidized fairly pricing deposit insurance eliminates inequitable transfers of wealth but it does not lead to an efficient equilibrium this paper shows that an alternative charter policy gives an efficient separating equilibrium the separating equilibrium segregates the market for insured transactions deposits from private information financial intermediation the analysis in this article provides support for the deposit insurance reform proposal in the recent 1993 national commission on financial institution reform recovery and enforcement ncfirre report to the president and congress and for merton and bodie s 1993 proposal both proposals impose a separating equilibrium that isolates insured transactions accounts and the public information traded assets that secure them from private information assets in the bank s portfolio the formal model developed here is designed to demonstrate the effect of charter policy on the efficiency of market equilibrium in an uncomplicated setting but the main result that a separating equilibrium is more efficient is extremely robust with respect to the model specification the model has two types of financial intermediaries intermediaries that hold nontraded private

land allocation effects of the global ethanol surge predictions from the international fapri model we quantify the emergence of biofuel markets and its impact on world agriculture using the multimarket multicommodity international fapri model the model incorporates trade offs between biofuel feed and food production and consumption and international feedback effects of the emergence through world prices and trade we shock the model with exogenous changes in ethanol demand first in the united states then in brazil and other countries and compute shock multipliers for land allocation decisions for important crops and countries the brazilian ethanol expansion using sugarcane has fewer consequences on existing arable land allocation than the u s ethanol expansion does using corn feedstock

competition and pricing in the credit card market many credit card issuers charge fixed rates that remain the same for three to five years while the rest charge variable rates that are indexed to market rates the presence of these two distinct rate types forces prices at firms selling an otherwise identical product to move asynchronously variable rates move one for one with the index while fixed rates stay constant empirical and theoretical analysis shows that this pricing structure provides an explanation for the simultaneous yet seemingly contradictory existence of high rate cost margins and aggressive non price competition for new customers a phenomenon that existed in the credit card market in the early 1990s

the rigidity of prices this paper uses evidence on individual transaction prices to analyze price behavior the evidence shows that for many transactions pricesremain rigid for periods exceeding one year the rigidity of price ispositively correlated with industry concentration for several productsthe correlation of price changes across buyers is low the paper alsoinvestigates the relationship between price rigidity price change andthe length of time a buyer and seller have been doing business together the author interprets the evidence as emphasizing the importance of nonprice rationing and the inadequacy of models in whichprice movements alone clear markets copyright 1986 by american economic association

the transmission mechanism in a changing world this paper aims at improving the understanding of the transmission of shocks across countries and how this transmission may have changed over time by employing a model that allows for parameter changes across regimes we show that transmission of shocks from the us to european countries may depend on the values of transition variables such as financial prices exchange rates international capital flows trade links and monetary policy instruments we also show that transmission mechanisms estimated with the proposed models have good performance in describing the 2001 downturn in some european countries as an effect of a us shock more generally the models have a good forecasting performance over short horizons

why has the u s economy become less correlated with the rest of the world in this paper we do two things first we document that over the last 40 years the u s business cycle has become less synchronized with the cycle in the rest of the world second we try to explain why this has happened we use a general equilibrium model as a tool to discriminate between two alternative explanations i a change in the nature of real shocks and ii an increase in u s financial integration with the rest of the world our results indicate that financial integration has played the major role in producing the observed changes in international co movement

optimum pricing policy under stochastic inflation we describe aggregate inflation as a stochastic process in which the rate of change of the price level can be positive or zero where the times spent in each state are of random duration this class of processes includes two state markov chains and renewal processes as special cases it is shown that the optimal pricing policy of a monopolistic firm with non convex costs of price adjustment is s s in its real price i e its nominal price relative to the price level a basic certainty equivalence result is proved i e the firm behaves as if it faces a certain and fixed rate of inflation higher than the actual expected rate the difference between the two rates being a risk premium which depends on the real interest rate and the parameters of the stochastic process one can thus apply previous results from the case of certainty sheshinski and weiss review of economic studies 1977 to obtain comparative static results in particular one finds that an increase in the variance of expected inflation leads firms to choose a pricing policy with larger amplitude in real price the paper also addresses the question of consistency in firms expectations when the price level is determined by the firms actions in this paper we consider pricing policies of individual firms in an inflationary environment each firm expects the general price level to increase and must determine the rate of increase of its own price it is assumed that the firm incurs an adjustment cost when it changes its nominal price consequently firms choose to change prices occasionally rather than continuously

multimarket contact competition and pricing in banking abstract in this paper we assess the impact of multimarket contact of banks on their market power by means of a simultaneous equation model in which the divergence of price from marginal cost is a function of multimarket linkages the model is estimated using aggregate data from the italian regions for the years 1997 2009 our results show that multimarket contact is positively and significantly correlated to the market power index and is also connected to both home and non home market concentration the evidence is robust to changes in model specification and multimarket contact measures and supports the idea that firms which have a greater amount of contact are more likely to collude

the impacts of biofuel targets on land use change and food supply a global cge assessment this study analyzes the long term impacts of large scale expansion of biofuels on land use change food supply and prices and the overall economy in various countries or regions using a global computable general equilibrium model augmented by a land use module and detailed representation of biofuel sectors the study finds that an expansion of global biofuel production to meet currently articulated or even higher national targets in various countries for biofuel use would reduce gross domestic product at the global level however the gross domestic product impacts are mixed across countries or regions the expansion of biofuels would cause significant land re allocation with notable decreases in forest and pasture lands in a few countries the results also suggest that the expansion of biofuels would cause a reduction in food supply although the magnitude of the impact on food supply at the global level is not as large as perceived earlier it would be significant in developing countries like india and those in sub saharan africa agricultural commodities such as sugar corn and oil seeds which serve as the main biofuel feedstocks would experience significant increases in their prices in 2020 compared with the prices at baseline due to the expansion of biofuels to meet the existing targets

the great recession us dynamics and spillovers to the world economy abstract this paper provides an empirical investigation of both the within us and international channels of transmission of macroeconomic and financial shocks by means of a 50 country macroeconometric model estimated over the 1980 2009 period including measures of excess liquidity and financial fragility specifically designed in order to evaluate the relevance of the boom bust credit cycle view put forward as an interpretation of the recent great recession episode we find that such a view is consistent with the empirical evidence moreover concerning the real effects of financial shocks within the us we detect stronger evidence of an asset prices channel rather than a liquidity channel concerning the spillovers to the world economy we find that while financial disturbances are transmitted to foreign countries through us house and stock price dynamics as well as excess liquidity creation the trade channel is the key trasmission mechanism of real shocks

measuring the determinants of business cycle synchronization using a panel approach abstract this paper investigates the gdp synchronization determinants using a new index for panel data that captures time variability effects although most of our evidence is in line with previous studies the effect of financial openness differs from the standard findings

the cyclicality of price cost margins in banking an empirical analysis of its determinants i introduction in this paper we study the cyclical behavior of price cost margins in banking calculated as the difference between the interest rate on loans and deposits using time series quarterly data for the period 1979 2005 in the united states this cyclical behavior of banks price cost margins a key fact about business fluctuations has received little attention before dueker and thornton 1997 find evidence that in cyclical downturns banks opt for a relatively high price cost margin however they focus exclusively on the markup of the bank prime lending rate over the marginal cost of funds for banks mandelman 2006 presents evidence on the cyclicality of margins for a large sample of countries and uses foreign bank penetration to explain the behavior of margins 1 in olivero 2005 aliaga diaz 2006 and aliaga diaz and olivero 2010a we document the countercyclicality of banks price cost margins in the united states in that paper we do so using an atheoretical methodology based on var forecast errors to measure comovement between variables 2 in this paper we build on this atheoretical evidence and take a step further by constructing an empirical model of the determinants of the cyclical behavior of margins here we take a theory based approach to decide on the inclusion of the relevant regressors that belong to this model doing so allows us to contribute to the literature by providing potential explanations for the previously documented countercyclical nature of margins monetary policy and credit risk could be suggested as the main and potentially the only determinants of the cyclical behavior of margins on the one hand the bank lending channel of monetary transmission predicts that the federal funds rate as a monetary policy indicator and margins are directly related therefore if policy rates exhibit a particular cyclical behavior not controlling for monetary policy could bias the estimations on the cyclical behavior of margins on the other hand credit risk is expected to be countercyclical and to raise margins so that default should help explain the countercyclicality of the latter based on these two observations our empirical methodology consists of two steps in a first step we test whether the negative and significant contemporaneous sample correlations between margins and a business cycle indicator are robust to the inclusion of controls related to monetary policy default risk and banking regulation results show it is so that there seems to be other channels through which fluctuations in the economy give rise to the observed countercyclicality of margins in a second step we look for these channels and offer several potential explanations for the observed behavior interest rate risk the economy s financial depth banks liquidity and capitalization and the share of total assets held by large banks all exert a significant impact on the behavior of margins over the business cycle these conclusions are consistent across alternative definitions of the margins and the business cycle indicator our work is linked to two strands of research in macroeconomics first our countercyclicality results are linked to the large literature on countercyclical markups in goods markets and its effects on aggregate demand started by rotemberg and saloner 1986 and rotemberg and woodford 1992 second price cost margins that vary endogenously and countercyclically in response to the state of the economy are a necessary condition for the existence of a financial accelerator as an amplifier of business fluctuations see for example bernanke and gertler 1989 and bernanke gertler and gilchrist 1998 therefore the countercyclical nature of price cost margins that we study here provides empirical support to the large body of literature in macroeconomic theory on this financial accelerator with price cost margins in the market for credit being countercyclical credit becomes more expensive in bad times firms may delay investment and production as a result and recessions may be exacerbated

financial integration within europe and the international transmission of business cycles among industrialized countries we exploit a dataset on financial integration within europe to answer a novel question in the international real business cycle rbc literature does financial integration within europe matter for the international transmission of business cycles between the united states and europe we find that it does and that as european countries become more financially integrated among themselves european business cycles start to decouple from those in the united states we show that this is true for three macro indicators of economic activity gross domestic product gdp consumption and investment and for five alternative measures of the degree of financial integration we also show that the effect of trade linkages becomes insignificant once financial factors are accounted for our work has interesting policy implications since it unveils the importance of further integration in the eu to slow down the transmission of aggregate shocks among industrialized nations

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

the price concentration relationship in banking the commonly observed positive correlation between market concentration and profitability may be explained by noncompetitive pricing behavior as argued by the structure performance hypothesis or by the greater efficiency of firms with dominant market shares as argued by the efficient structure hypothesis by examining the price concentration relationship instead of the profit concentration relationship this paper tests the structure performance hypothesis in a manner that excludes the efficient structure hypothesis as an alternative explanation of the results the results strongly support the structure performance hypothesis and are robust with respect to model specification measurement of concentration and econometric technique copyright 1989 by mit press
