deep habits price rigidities and the consumption response to government spending this paper inspects the deep habits mechanism originally used by ravn schmitt grohe and uribe 2006 to generate the positive comovement of public and private consumption observed in many var studies in their set up the price elasticity of demand is pro cyclical and it is optimal for the firm to lower the mark up while expanding production after the fiscal shock raising the demand for labor and the real wage consequently agents substitute consumption for leisure and overcome the negative wealth effect of the fiscal expansion here we show that increasing price stickiness reduces the impact of the fiscal shock on the real wage and hinders the rise of consumption if the degree of price stickiness is high enough consumption is crowded out this is in contrast to the role of price rigidities in the standard new keynesian model where they weaken the crowding out of consumption

the hazard of moral hazard untangling the asian crisis abstract the paper critically examines the explanations of the asian crisis which emphasize the role of national policies and institutions that allegedly created moral hazard by overprotecting the investors industrial policy crony capitalism and government guarantees accorded to banks and industrial firms that are considered too important to fail we also discuss the international dimension of the moral hazard argument in the presence of international monetary fund imf bail out the paper finds these explanations theoretically ill defined and empirically weak and argues that the prescriptions for changes in policy and institutions based on them are unlikely to prevent similar kinds of crises in the future

the control of technology alliances an empirical analysis of the biotechnology industry we examine the determinants of control rights in biotechnology alliances through three case studies and a quantitative analysis aghion and tirole 1994 argue that control rights will be assigned so as to maximize the value of the final output as long as the r d firm has sufficient financial resources consistent with this framework the allocation of control rights to the r d firm increases with the firm s financial resources the empirical evidence regarding the relationship between control rights and the stage of the project at the time the alliance is signed is more ambiguous

what accounts for the changes in u s fiscal policy transmission using vector autoregressions on u s time series for 1957 79 and 1983 2004 we find government spending shocks to have stronger effects on output consumption and wages in the earlier period we try to account for this observation within a dsge model featuring price rigidities and limited asset market participation specifically we estimate the structural parameters of the model for both periods by matching impulse responses model based counterfactual experiments suggest that most of the changes in fiscal policy transmission are accounted for by increased asset market participation and the more active monetary policy of the volcker greenspan period

nonseparable preferences frisch labor supply and the consumption multiplier of government spending one solution to a fiscal policy puzzle this paper proposes a theoretical explanation of the positive consumption multipliers of government spending often found in the data the explanation requires two ingredients first labor demand expands e g prices are sticky second general nonseparable preferences over consumption and leisure should be such that the two goods are substitutes that is frisch labor supply elasticity is lower than the constant consumption elasticity this implies that constant consumption labor supply shifts left existing empirical evidence on the relative magnitudes of the two elasticities supports this hypothesis the parametric conditions under which the result occurs are consistent with restrictions of concavity and noninferiority of consumption and leisure

rethinking the development agenda this paper calls for a development agenda based on five major premises 1 a more balanced form of globalisation based on a genuine respect for diversity 2 a broad view of macroeconomic stability which provides an adequate role for counter cyclical policies 3 the need to complement macroeconomic stability with active productive development policies 4 strong social policies and the mainstreaming of social objectives into economic policies to guarantee adequate linkages between economic and social development and 5 the recognition that development involves broader human development goals copyright 2002 oxford university press

boom and bust cycles external imbalances and the real exchange rate when the current account balance and net capital outflows do not exactly offset each other international payment flows arise payment flows into a country push the real exchange rate up payment outflows push it down this article uses a model of optimal consumption and portfolio choice to determine the factors that drive international payment flows during boom and bust cycles it shows that during such episodes capital inflows first exceed the deficit on current account strengthening the currency later on when the return on domestic capital reverts to its normal level the current account recovers yet the overall decline of the net foreign asset position provokes a fall of the real exchange rate even below its initial level case studies of countries experiencing rapid economic expansions followed by economic and financial meltdowns confirm the article s theoretical predictions

what do twins share a joint probit estimation of banking and currency crises we study the determinants of twin crises and investigate the direction of causality between banking and currency crises in emerging markets we model banking and currency crises as dynamic events correlated over time and jointly estimate their probability using panel data simulation techniques we show that banking and currency crises are closely intertwined and are driven by common fundamentals banking crises exhibit strong state dependence suggesting that countries that have experienced a banking crisis in the past are more prone to experience another crisis finally we find evidence of unobserved heterogeneity and autocorrelation in the error term structure

the political economy of the ecuadorian financial crisis this paper takes the unusual step of exploring economic hypotheses through interviews with key economic agents it focuses on the causes of ecuador s 1999 banking collapse within an eclectic framework with minskian elements broad support is found for endogenous explanations of financial crises and little backing for explanations such as accidents or policy mistakes interviewees argued that after the stabilisation programme of 1992 agents became euphoric and accumulated debt to finance imprudent levels of expansion that incentives for moral hazard led to financial corruption and excessive risk taking and that weak regulation after

ready for capital account convertibility abstract this paper investigates whether the impact of capital account convertibility on the long term volatility of economic growth depends on financial development it estimates a system of three simultaneous equations mean growth volatility of growth and financial development this allows for the study of both the impact of capital account liberalization on volatility as well as its direct impact on financial development results indicate that economies with low financial development fall prey to excess volatility arising from capital account openness while capital account openness itself has a significant positive impact on financial development the results are robust to alternative measures of financial development and volatility and to the removal of outliers

a developing country view of the current global crisis what should not be forgotten and what should be done macroeconomic theory will surely be affected by the current global crisis there are signs that some old theories and insights will have a comeback this paper argues that among them economists should not forget the lessons that have been learnt from three decades of several financial crises in developing countries we emphasise two important lessons first preventing crises in developing countries requires not only the regulation of domestic financial systems but also a consistent set of macroeconomic policies in particular we stress the need for consistency between the exchange rate rule the capital account regime and the domestic financial market regulations second financial crises in developing countries tend to worsen both the balance of payments and the fiscal balance traditional adjustment policies tend to exacerbate the recessive trends in output and employment this is just the opposite of what is required and what governments in developed countries are able to do developing countries should push for an agenda that helps them deal with these problems

investment shocks and consumption abstract several influential papers have argued that preferences featuring a weak wealth effect on labour supply are key to generate macroeconomic co movement across real variables in response to shocks using a fully general specification for the instantaneous utility function we show that the size of the wealth effect on labour supply is largely inconsequential for macroeconomic dynamics instead we find that edgeworth complementarity between consumption and hours worked is crucial in order to obtain co movement of key macroeconomic variables we consider investment shocks and we show that co movement can easily be achieved with non separable preferences in combination with a reasonable degree of nominal rigidity this holds even in the presence of sizeable wealth effects

real interest rates and growth improving on some deflating experiences tests of the mckinnon shaw hypothesis typically investigate the relationship between real interest rates and growth recent work has concluded that this relationship may be non monotonic this article investigates the role of real interest rate mismeasurement in explaining these non monotonicities when such mismeasurement is systematically related to growth it will produced biased empirical results after addressing these biases the article demonstrates that financial liberalisation may offer substantial economic gains in an average country raising real interest rates from 25 per cent to five per cent will increase real annual per capita gdp growth from zero to a relatively robust rate of two per cent

les liaisons dangereuses a minskyan approach to the relation of credit and investment in argentina during the 1990s we classify firms according to their financial behaviour in the short term using a minskyan taxonomy that classifies firms as hedge speculative and ponzi we measure financial constraints across that taxonomy using panel data for argentina during 1992 2001 after controlling for profitability we find that firms with an oppressed financial structure in the short term had to rely on their internal funds for long term investment we interpret this finding from a minskyan keynesian framework arguing that credit allocation followed conventional rules about the quality of borrowers and not necessarily about the quality of the project because of being a highly unstable country argentinean firms quality is defined on a short term basis

expectations learning and business cycle fluctuations this paper explores an alternative theory based on learning dynamics in the con text of an otherwise standard stochastic growth model we consider an environment in which households and firms have an incomplete model of the macroeconomy knowing only their own objectives constraints and beliefs agents are optimizing have a completely specified belief system but do not know the equilibrium map ping between primitive disturbances the aggregate state of the economy and mar ket clearing prices by extrapolating from historical patterns in observed data they approximate this mapping to forecast variables that are exogenous to their decision problems such as the rental rate of capital and the real wage this belief structure has the property that beliefs affect the true data generating process of the economy which in turn affects belief formation the economy is therefore self referential shifts in beliefs about future returns to labor and capital affect current market clear ing prices which in turn can reinforce beliefs in this environment current prices can become less informative about future economic conditions generating fluctuations in real activity this kind of mechanism driving business cycle fluctuations is found in early writ ings on macroeconomic dynamics for example alfred c pigou 1927 on page 122 writes

intellectual property rights and the welfare effects of agricultural r d the profound changes that have affected agriculture in modern times are perhaps best illustrated by the evolution of production techniques due to mechanization new chemical inputs such as herbicides pesticides and fertilizers genetic selection of crops and animals new crop varieties and countless other technical and organizational improvements these innovations have allowed a generalized increase in physical output while at the same time agriculture has suffered a massive exodus of labor forces towards the non farm sectors indeed a stylized fact of developed countries post war growth is that productivity in agriculture has grown faster than in other sectors jorgenson and gollop 1992 this remarkable record naturally begs the question of what is at its root and a view that commands considerable consensus is that agricultural productivity growth is due to past investments in scientific research and development r d

trips trade and technology transfer a north south model of unintentional technology transfer is developed where the stringency of southern patent protection provides the institutional backdrop for a strategic game in a high tech goods market the appropriability regime is set endogenously and combines elements of imperfect southern patent protection with the protection afforded by market made northern technology masking less stringent protection of northern intellectual property can work much like other strategic trade policies therefore developed countries appear to be right in demanding discussion of intellectual property rights in gatt

estimating the effect of unearned income on labor supply earnings savings and consumption evidence from a survey of lottery players this paper provides empirical evidence about the effect of unearned income on earnings consumption and savings using an original survey of people playing the lottery in massachusetts in the mid 1980 s the effects of the magnitude of lottery prizes on economic behavior are analyzed the critical assumption is that among lottery winners the magnitude of the prize is randomly assigned it is found that unearned income reduces labor earnings with a marginal propensity to consume leisure of approximately 11 percent with larger effects for individuals between 55 and 65 years old after receiving about half their prize individuals saved about 16 percent

the effect of government spending on private consumption a puzzle the empirical finding that cyclical changes in government spending tend to be associated with positive responses of private consumption has been interpreted as a challenge for representative agent intertemporal optimizing theories which usually imply that the negative wealth effect of higher fiscal spending reduces the households consumption and leisure the present paper shows that the evidence can be explained by a standard real business cycle type model with a nonadditively separable utility function and a small intertemporal consumption elasticity higher fiscal spending can raise consumption and lower investment as in the data the nonseparable utility model is shown to imply the same consumption euler equation as a model with rule of thumb consumers who mechanically spend their income

clearing up the fiscal multiplier morass bayesian prior predictive analysis of five nested dsge models suggests that model specifications and prior distributions tightly circumscribe the range of possible government spending multipliers multipliers are decomposed into wealth and substitution effects yielding uniform comparisons across models by constraining the multiplier to tight ranges model and prior selections bias results revealing less about fiscal effects in data than about the lenses through which researchers choose to interpret data when monetary policy actively targets inflation output multipliers can exceed one but investment multipliers are likely to be negative passive monetary policy produces consistently strong multipliers for output consumption and investment

determinants of patent rights a cross national study abstract this paper presents an index of patent rights for 110 countries for the period 1960 1990 the index is used to examine what factors or characteristics of economies determine how strongly patent rights will be protected the evidence does indicate that more developed economies tend to provide stronger protection but the underlying factors which influence patent protection levels are the country s level of research and development r d activity market environment and international integration which are correlated with its level of development the results qualify however that r d activity influences patent protection levels after a nation s research sector reaches a critical size an implication of this is that to raise patent protection levels in weakly protecting countries it is important to foster a significant research base in those countries and thereby create incentives for protecting patent rights

third world debt and its effects on the british economy a southern view of economic mismanagement in the north when citicorp one of the largest banks in the world announced its decision to make a us 3 billion provision against third world loans in may 1987 almost every commentator agreed that it represented a turning point in the debt crisis it marked the end of the major banks policy of turning a blind eye to the debt crisis after years of unrealistic projections false hopes and promises in the north and with a third world debt already well above us 1 000 billion the banks suddenly began to speak of debt realities see for instance morgan guaranty s world financial markets june july 1987 this realism was a pre condition for overcoming one of the main stumbling blocks to any solution of the crisis namely the reluctance of the main creditor banks to acknowledge the impossibility of recovering the full face value of their ldcs loans

consumption heterogeneity employment dynamics and macroeconomic co movement abstract real business cycle models rely on total factor productivity tfp shocks to explain the observed co movement among consumption investment and hours however an emerging body of evidence identifies investment shocks as important drivers of business cycles this paper shows that a neoclassical model consistent with observed heterogeneity in labor supply and consumption across employed and non employed can generate co movement in response non tfp shocks estimation reveals fluctuations in the marginal efficiency of investment that explain the bulk of business cycle variance in consumption investment and hours a corollary of the model s empirical success is the labor wedge that is not important at business cycle frequencies

foreign patent rights and high tech exports evidence from taiwan this paper conducts a consecutive pooled data analysis from 1989 to 2000 to investigate the relationship between foreign patent rights fprs and the exports of three high tech industries in taiwan the semiconductor the information and the communication equipment industries following smith s model setup empirical results indicate that both market expansion and market power effects do exist in taiwan s case in addition this paper proposes a new hypothesis in which the importing country may exhibit a stronger r d ability than the exporting country a case that has not been considered in earlier empirical work finally a test is made to determine if a trips trade related intellectual property rights agreement has any impact on the fprs exports relationship and no evidence is found of a structural change after the implementation of trips

the circular relationship between inequality leverage and financial crises in this paper we put into perspective the recent literature which points to inequality as a possible cause of credit bubbles by reintegrating it into a more general analysis on the two way relationship between inequality and finance we focus more specifically on situations where high inequalities and widespread access to credit coexist and argue that even when institutions maintain more or less equal access to finance there may be a dynamic positive circular relationship between inequality and financial development however even if there is some evidence in the literature of a positive causal impact of inequality on credit this does not preclude other important cofounding factors the conclusions concerning the distributional impact of finance are more ambiguous a survey of the empirical literature highlights several issues that must be tackled first endogeneity reverse causality and coincidental factors are major concerns second the choice of consistent measurements for the key variables both credit and inequality has strong empirical implications and must be grounded on relevant theoretical channels third those circular dynamics have substantial policy implications for emerging economies since an increasing number face a joint increase in inequality and credit

currency crises and institutions abstract this study furthers recent literature on currency crises and institutions the main objective is to re evaluate the causes of currency crises by focusing on the role played by a broader array of institutional factors and crisis episodes than have previously been considered while at the same time controlling for economic factors our dataset consists of over 30 countries covering 13 institutional factors for the period 1984 2002 two questions are addressed they are 1 what mix of institutions may contribute to or set the stage for a currency crisis and 2 what mix of institutions may affect the depth of currency crises as measured by a decline in output our findings reveal that institutional as well as economic factors affect the probability of currency crises and that worse institutions are associated with bigger contractions in output during the crisis in general our strongest results regarding institutions show that corruption a de facto fixed exchange rate regime weak government stability and weak law and order increase the probability of a currency crisis we find mixed evidence that deposit insurance the removal of capital controls a lack of central bank independence financial liberalization and civil law increase the chance of crisis we find a similar set of factors worsens the contraction in output during a crisis except for deposit insurance which we find moderates the contraction in output

on the minimum degree of returns to scale in sunspot models of the business cycle abstract bennett and farmer j econ theory 93 2000 118 claim that the degree of increasing returns to scale required for indeterminacy in a single sector growth model can be lowered by allowing for preferences that are non separable in consumption and leisure in this paper i show that the example they give violates concavity in a more general setup which does not impose specific functional forms on utility i prove that there are no concave utility functions compatible with indeterminacy if the elasticity of scale is lower than the inverse of the labor share in production

the impact of patent protection on us pharmaceutical exports to developing countries this article provides evidence that patent protection can have a positive effect on trade by analysing the impact of the implementation of intellectual property rights ipr in developing countries on the us exports of pharmaceutical products following intense lobbying efforts from the us pharmaceutical industry to have the trade related aspects of intellectual property rights trips agreement included in the creation of the world trade organization wto a gravity model using panel data from 1995 to 2010 suggests that the implementation of minimum standards of patent protection has increased us exports of pharmaceuticals to 108 nonadvanced countries

nonseparable preferences fiscal policy puzzles and inferior goods nonseparable preferences over consumption and leisure can generate an increase in private consumption in response to government spending as found in the data in a frictionless business cycle model however the conditions on preferences required for these result to obtain hold if and only if the consumption good is inferior similarly positive co movement of consumption and hours worked occurs if and only if either consumption or leisure is inferior

patent rights and trade analysis of biological products medicinals and botanicals and pharmaceuticals this article analyzes the effects of foreign patent rights on u s bilateral exports the empirical analysis covers three highly disaggregated drug industries over three decades we estimate bilateral trade equations for each industry using cross country data on the strength of national patent rights the findings show that strong foreign patent rights enhance the market power of u s drug exporters across countries with weak imitative abilities alternatively strong foreign patent rights stimulate the market expansion of u s drug exports across countries with strong imitative abilities these effects are larger in magnitude during the 1980 90s relative to the 1970s copyright 2002 oxford university press

pharmaceutical patents prices and welfare losses policy options for india under the wto trips agreement c oncerns on the effect of product patents on the prices of medicines have been acute in many developing countries which up to the entry into force of the world trade organisation wto agreement on trade related aspects of intellectual property rights trips in 1995 could and did disallow such patenting in their national patent laws with trips all members of and those seeking accession to the wto have to make available with limited exceptions both product and process patents in every sector including pharmaceuticals more specifically trips provides that all wto members have to receive product patent applications for pharmaceuticals from the date of establishment of the wto i e january 1995 it is important to note that even under the trips regime patents are to be granted only on applications received from 1995 onwards for new patentable pharmaceutical inventions thus prices of existing pharmaceuticals already on the market or even those covered by patent

international overborrowing a decomposition of credit and currency risks summary the severity of the financial crises enveloping the tiger economies of southeast asia in 1997 came as a surprise to many observers this paper uses a simple fisherian model of the overborrowing syndrome to compare the asian crises of 1997 with earlier overborrowing episodes in mexico and chile while important similarities exist the crises in southeast asia have been exacerbated by the unhedged foreign exchange positions of asian banks these open currency positions not only imposed significant additional losses on the banks following devaluation they also magnified the scale of overborrowing during the cycle s initial boom phase failure to limit the exposure of banks to foreign exchange risk therefore increased the magnitude of the boom bust overborrowing cycle both ex ante and ex post the paper highlights the importance of effective regulation and supervision of capital markets with a focus on limiting the speculative currency positions of banks especially those that form the core of the domestic payments system and therefore enjoy a possibly implicit public guarantee improving the institutional infrastructure of financial supervision is the only effective way of mitigating the macroeconomic costs of overborrowing

effects of financial liberalisation and political connection on listed chinese firms financing constraints this paper examines the impact of recent financial liberalization in china on the financing constraints of publicly listed chinese firms with and without politically connected ceo chairman two continuous indices are used to measure the evolution and intensity of financial reforms a financial liberalization index and a capital control index the results indicate that while firms without politically connected ceo chairman face significant financing constraints and politically connected firms do not financial liberalization has reduced the constraints for the former similarly lower capital control in china s equity market lessens credit constraints for non connected firms no statistically significant impact is detected with regards to firms that have ceo chairman with powerful political background

government spending entry and the consumption crowding in puzzle this article documents empirically that net firm entry robustly rises after a u s government spending expansion we use this new finding to test the empirical validity of various model features that have been proposed to generate consumption crowding in after positive expenditure shocks endogenous entry models typically fail to generate the observed joint increase in consumption and entry model features that dampen the wealth effect such as rule of thumb households or complementarity between labor and consumption in preferences tend to reduce entry we show that utility or productivity enhancing public spending can reconcile the model with our documented fact and performs well empirically

do stronger intellectual property rights induce more agricultural trade a dynamic panel data model applied to seed trade do stronger intellectual property rights iprs induce more agricultural trade based on panel data for 60 countries during 1990 2000 and using a dynamic panel data model this article assesses whether and how national differences in iprs affect the trade flow of planting seeds imports from the united states the empirical results show that whether or not a country adheres to iprs agreements has no discernible impact on planting seeds that are imported from the united states implying that the strengthening of iprs seems not to induce more agricultural trade this result sheds some light on the debate in the theoretical literature on the importance of iprs and trade

financial crisis in southeast asia dispelling illusion the minskyan way this paper extends minsky s financial instability hypothesis to the case of the open liberalised economy making it possible to put forward a specifically minskyan account of the road to the financial crisis in southeast asia 1997 1998 the analysis suggests that the threats to growth and employment emanating from the financial sector which minsky identified in the closed economy setting are much intensified in open liberalised developing economies financial liberalisation is an important key factor in this process rival explanations of the crisis are examined and rejected in favour of the extended minskyan explanation the policy implications are derived and discussed copyright 2002 oxford university press

two fiscal policy puzzles revisited new evidence and an explanation abstract this paper examines two fiscal policy puzzles related to the effects of government spending shocks contrary to theoretical predictions recent empirical evidence suggests a crowding in of consumption and a depreciation of the real exchange rate after a government spending increase while several studies have been made to reconcile the conflicting results this paper provides new time series evidence and proposes an alternative explanation using the japanese data the empirical responses of consumption and the real exchange rate after government spending shocks are shown to be well replicated by an estimated medium scale open economy dynamic stochastic general equilibrium dsge model augmented with i edgeworth complementarity between private and government consumption and ii productive public capital furthermore sensitivity analysis suggests that the combination of edgeworth complementarity home bias and incomplete asset market allows the model to account for an immediate increase in consumption and for a hump shaped depreciation of the real exchange rate after a government consumption shock this result is potentially important in preventing the model from showing the consumption real exchange rate anomaly after the shock

dollarization of bank deposits causes and consequences abstract this paper assesses the benefits and risks associated with dollarization of bank deposits we provide novel empirical evidence on the determinants of deposit dollarization its role in promoting financial development and on whether dollarization is associated with financial instability we find that a the credibility of macroeconomic policy and the quality of institutions are both key determinants of cross country variations in dollarization b dollarization is likely to promote financial deepening only in a high inflation environment and c financial instability is likely higher in dollarized economies the implications of these findings for financial sector and monetary policies are briefly discussed

korea the misunderstood crisis abstract the article argues against the conventional wisdom that the current korean crisis is a crisis from underregulation rather than from overregulation it argues that ill managed financial liberalization abandonment of investment coordination and poor exchange rate management were the underlying causes of the crisis it then argues that while certain structural changes made such policy shifts somewhat inevitable there were also poor strategic choices and ideological prejudices involved the article finally discusses whether the current international monetary fund program of institutional reform in the anglo american direction will be able to revive the korean economy in the long run

the effects of a money financed fiscal stimulus abstract i analyze the effects of a money financed fiscal stimulus and compare them with those resulting from a conventional debt financed stimulus i study the effects of both a tax cut and an increase in government purchases with and without a binding zero lower bound zlb on the nominal interest rate when the zlb is not binding a money financed fiscal stimulus is shown to have much larger multipliers than a debt financed fiscal stimulus that difference in effectiveness persists but is much smaller under a binding zlb nominal rigidities are shown to play a major role in shaping those effects

housework and fiscal expansions in an otherwise standard business cycle model with housework calibrated consistently with data on time use we discipline complementarity between consumption and hours worked and relate its strength to the size of fiscal multipliers evidence on the substitutability between home and market goods confirms that complementarity is an empirically relevant driver of fiscal multipliers however in a housework model substantial complementarity can be generated without imposing a low wealth effect which contradicts the microeconomic evidence also explicitly modeling housework matters for assessing the welfare effects of government spending which are understated by theories that neglect substitutability between home produced and market goods

estimating the euler equation for output new keynesian macroeconomic models have generally emphasized that expectations of future output are a key factor in determining current output the theoretical motivation for such forward looking behavior relies on a straightforward generalization of the well known euler equation for consumption in this paper we use maximum likelihood and generalized method of moments gmm methods to explore the empirical importance of output expectations we find little evidence that rational expectations of future output help determine current output especially after taking into account the small sample bias in gmm

europe s great depression coordination failure after the first world war in this paper i survey and reinterpret the extensive literature on europe s great depression i argue that europe could not exploit its vast economic potential after 1918 because the war had not yet come to an end indeed it did not end before 1945 both domestic and international institutions suffered from a lack of reciprocal trust and commitment which can be clearly illustrated in the realm of monetary policy but affected many other areas of policy making such as energy or migration policies these institutions in turn affected expectations and thereby the extent to which for example expansionary policies could be effective

developing countries changing nature of financial integration and new forms of external vulnerability the brazilian experience this article argues using the example of brazil that the changing nature of developing and emerging countries decs financial integration has created new forms of external vulnerability causing large and volatile capital and exchange rate movements despite sound fundamentals and a substantial reduction in its traditional external vulnerabilities the brazilian real has been one of the most volatile currencies over recent years the article argues that this has been the result of the surging exposure of foreign investors in an increasingly complex set of very short term domestic currency assets following a minskyan analysis we demonstrate that the changing nature of brazil s external vulnerability confirms both the inherent and endogenous instability of international capital flows and decs subordinate role in the international financial system we conclude with policy recommendations to reduce decs external vulnerability sustainably

financial development and the instability of open economies this paper introduces a framework for analyzing the role of financial factors as a source of instability in small open economies our basic model is a dynamic open economy model with a tradeable good produced with capital and a country specific factor we also assume that firms face credit constraints with the constraint being tighter at a lower level of financial development a basic implication of this model is that economies at an intermediate level of financial development are more unstable than either very developed or very underdeveloped economies this is true both in the sense that temporary shocks have large and persistent effects and also in the sense that these economies can exhibit cycles thus countries that are going through a phase of financial development may become more unstable in the short run similarly full capital account liberalization may destabilize the economy in economies at an intermediate level of financial development phases of growth with capital inflows are followed by collapse with capital outflows on the other hand foreign direct investment does not destabilize

intellectual property rights and the world trade organization retrospect and prospects this paper analyzes the main economic issues of intellectual property rights iprs protection in the context of the world trade organization wto a retrospective view on the establishment of the trips trade related aspects of intellectual property rights agreement a still controversial accomplishment of the uruguay round of trade liberalization is provided the paper reviews the economic rationale for the harmonization of iprs drawing both on economic theory considerations as well as emerging empirical evidence the logic of linking ipr protection and trade in the context of the wto is also re examined some specific attention is devoted to the implications of trips for agricultural and biotechnology innovations the impact that ipr protection can have in promoting growth and development and the relation of iprs with other economic policies is discussed the paper concludes with an analysis of the prospects for more or less iprs related consensus in the current round of wto negotiations

the role of the state in financial markets this paper reexamines the role of the state in financial markets and identifies seven major market failures that provide a potential rationale for government intervention in practice government interventions in capital markets even in industrial countries have been pervasive the paper provides a taxonomy of those interventions with respect to both the objectives they serve and the instruments they employ there is a role for the government in financial markets but the success of government interventions has been mixed it is important that interventions be well designed the paper sets out principles for government regulatory interventions and applies them to prudential regulation it then examines three other areas of intervention directed credit finanical repression and competition policy and identifies circumstances in which some amount of financial repression may actually be beneficial

the economics of intellectual property rights discussion intellectual property rights iprs are becoming more important in agriculture as agriculture becomes increasingly industrialized as the outcome of the recent round of the general agreement on tariffs and trade gatt takes hold and as government withdraws from and or changes the nature of its research and development r d effort the two papers presented in this session provide a good starting point for an analysis of the economic impacts of iprs lesser s paper is an excellent overview of the history and forms of iprs he also provides a good survey of the ipr literature in agriculture especially with regard to the impact of ipr legislation such as plant breeders rights langford s paper stresses the incentive effects of iprs arguing that iprs facilitate institutional change and encourage competition and economic growth a focus of both papers is the effect of iprs on the incentives for r d and the structure of the agricultural industry the issues of incentives and structure are not only important but also closely linked as i will argue in this paper the extensive use of iprs in agriculture can occur only if technology firms are oligopolistic and possesses market power with this type of industrial structure iprs create the incentives not only for increased innovation but also for technology firms to focus their attention on certain types of technologies paradoxically iprs can also create conditions where innovations that are economically feasible are not carried out or are not adopted in this paper i will develop the linkage between iprs and industrial structure and discuss some of the implications of this structure for agricultural r d

the new keynesian cross abstract the new keynesian nk cross is a graphical and analytical apparatus for heterogeneous agent hank models expressing key aggregate demand objects mpc and multipliers as functions of heterogeneity parameters it affords analytical insights into monetary fiscal and forward guidance multipliers and replicates the aggregate implications of quantitative hank the key parameter the constrained agents income elasticity to aggregate income depends on fiscal redistribution when it is larger smaller than one the effects of policies and shocks are amplified dampened with uninsurable idiosyncratic uncertainty this translates intertemporally through compounding discounting in the aggregate euler equation into further amplification dampening of future shocks

how trade related are intellectual property rights abstract there is little empirical evidence about whether differing international levels of patent protection influence trade flows if a nation strengthens its patent laws it could experience higher or lower imports we specify an empirical model in which deviations of bilateral sectoral imports from anticipated levels are related to income trade barriers and patent laws patent regulations in the importing country are corrected for endogeneity through the use of instrumental variables the results of the final equations indicate that increasing patent protection has a positive impact on bilateral manufacturing imports into both small and large developing economies

the effects of government spending on real exchange rates evidence from military spending panel data abstract using panel data on military spending for 125 countries we document new facts about the effects of changes in government purchases on the real exchange rate consumption and current accounts in both advanced and developing countries while an increase in government purchases causes real exchange rates to appreciate and increases consumption significantly in developing countries it causes real exchange rates to depreciate and decreases consumption in advanced countries the current account decreases in both groups of countries these findings are not consistent with standard international business cycle models we discuss potential sources of the differences between advanced and developing countries in the responses to spending shocks

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

three and a half cycles of mania panic and asymmetric crash east asia and latin america compared this paper argues that despite some significant differences the 1982 debt crisis the 1994 mexican crisis and the 1997 east asian crisis share the common characteristic that over lending and over borrowing are basically endogenous market failures of over liquid and under regulated financial markets along the lines described by kindleberger s manias panics and crashes although these crashes have tended to be asymmetric as the largest international lenders have emerged relatively intact the paper concludes with a discussion of brazil s increasing vulnerability to a sudden collapse of confidence and withdrawal of finance which indicates the probability of another impending crisis

can public spending boost private consumption this paper analyses the effects on private consumption from an increase in productive and unproductive public spending a new keynesian model incorporating price and wage rigidities monetary policy and various fiscal rules is developed and estimated using bayesian techniques to capture the key cyclical characteristics of the us economy we find that price and wage rigidities along with a positive shock to the part of public spending that is productive are suficient to boost private consumption moreover we show that this initial positive reaction of private consumption is adequate to create a positive present value consumption multiplier for more than five years finally we show that our main results remain robust to changes in the monetary rule and the various methods of deficit financing

the effect of patents on trade abstract in contrast with quotas and tariffs it is theoretically ambiguous whether fewer or weaker rules over intellectual property rights will increase or decrease trade in patentable goods the prevailing view is that anticipation of imitation reduces exporters incentive to export goods to jurisdictions with weak patent regimes this empirical paper uses new measures of how the destination country patent system can affect trade in contrast with existing studies which assume would be exporters can always get a patent in the target foreign market we construct measures of the bias against foreign patent applicants and patents which may block imported goods we find evidence that the presence of destination country blocking patents has the larger negative impact on international trade being refused a patent also has a negative impact on trade but the magnitude is smaller

financial liberalization credit constraints and collateral investment in the mexican manufacturing sector abstract we examine the impact of financial liberalization on fixed investment in mexico using establishment level data from the manufacturing sector in addition to analyzing changes in cash flow sensitivities an innovative approach explores the role of real estate as collateral and addresses a potential censoring problem the results suggest that financial constraints were eased for the smallest firms but not for larger ones however the importance of possessing real estate increased given banks reliance on collateral in their lending the results also provide microeconomic evidence consistent with the role attributed to financial accelerator mechanisms during lending booms and during post crisis recessions

assessing the implications of intellectual property rights on plant and animal agriculture many readers over their careers will have shared my experience of initiating some really innovative work only to learn that it had been done and done better thirty years earlier that is one key attraction of research on intellectual property rights iprs for plants and animals they are in the main very recent so whatever one does cannot have a direct antecedent indeed to date little economic research has been completed on the implications of expanding ipr protection for living agricultural inputs protection in the united states for asexually propagated plants has been available since 1930 1990 in canada for sexually propagated plants for over twenty five years and for patented plants for a dozen years see below however only in the last year has significant acreage of patented bioengineered plants some 2 5 million in total been planted with higher levels going in the ground in the united states and canada as this paper is being drafted those crops are primarily herbicide resistant beans canola and corn bt producing corn cotton and potatoes and virus resistant squash james and krattiger only one livestock application to my knowledge has been patented a pig in australia with a controllable growth hormone but as yet it is not a commercial product what has been explored extensively in the literature are expressed concerns about iprs on farm structure ethics university industry relationships information exchange and related matters see e g kloppenburg nor is the debate limited to the united states or developed countries the international enhancement of

reconciling jaimovich rebello preferences habit in consumption and labor supply abstract this note studies a form of a utility function of consumption with habit and leisure that a is compatible with long run balanced growth b hits a steady state observed target for hours worked and c is consistent with micro econometric evidence for the inter temporal elasticity of substitution and the frisch elasticity of labor supply employing jaimovich rebello preferences our results highlight a constraint on the preference parameter needed to target the steady state frisch elasticity this leads to a lower bound for the latter that cannot be reconciled empirically with external habit but the introduction of a labor wedge solves the problem we also propose a dynamic frisch inverse elasticity measure and examine its business cycle properties

international standards for intellectual property protection and r d incentives abstract we examine the effect of alternative standards for intellectual property protection uniform protection based on the gatt principle of non discrimination provides domestic and foreign firms with the same level of protection discriminatory protection based on section 337 of the u s trade laws provides different levels of protection depending upon where the firm is located we show that discriminatory protection may not increase and may decrease domestic r d the effect of asymmetric patent protection depends on whether the rivals have pre existing products on the costs of r d and on the value of the potential innovation

the international monetary system in the last and next 20 years the last two decades have seen far reaching changes in the structure of the international monetary system europe moved from the european monetary system to the euro china adopted a dollar peg and then moved to a basket band and crawl in 2005 emerging markets passed through a series of crises leading some to adopt regimes of greater exchange rate flexibility and others to rethink the pace of capital account liberalization interpreting these developments is no easy task some observers conclude that recent trends are confirmation of the bipolar view that intermediate exchange rate arrangements are disappearing while members of the fear of floating school conclude precisely the opposite we show that the two views can be reconciled if one distinguishes countries by their stage of economic and financial development among the advanced countries intermediate regimes have essentially disappeared this supports the bipolar view for the group of countries for which it was first developed within this subgroup the dominant movement has been toward hard pegs reflecting monetary unification in europe while emerging markets have also seen a decline in the prevalence of intermediate arrangements these regimes still account for more than a third of the relevant subsample here the majority of the evacuees have moved to floats rather than fixes reflecting the absence of emu like arrangements in other parts of the world among developing countries the prevalence of intermediate regimes has again declined but less dramatically where these regimes accounted for two thirds of the developing country subsample in 1990 they account for a bit more than half of that subsample today as with emerging markets the majority of those abandoning the middle have moved to floats rather than hard pegs the gradual nature of these trends does not suggest that intermediate regimes will disappear outside the advanced countries anytime soon barry eichengreen and raul razo garcia

product and process innovation in the product life cycle estimates for u s manufacturing industries many theoretical analyses of international trade focus on the effects and endogenous determination of product innovation technology transfer and product obsolescence despite these theoretical innovations few direct tests of the empirical power of product cycle models have been conducted although a number of studies have examined general relationships between trade and innovation usually measured by expenditures on research and development rd and then estimate these predictions using data for eleven two digit manufacturing industries in the united states during the period from 1974 to 1988 the distinction between productand process oriented technological change is important because it yields predictions that aid in assessing the power of the product cycle models most empirical studies aggregate productand process oriented technological change with the notable exceptions of the studies of productivity growth by link 22 and terlecky 31

contracts intellectual property rights and multinational investment in developing countries abstract the policy debate between multinational firms favoring strong contract law and host country governments who often oppose such protection motivates the paper local agents managers learn the multinational s technology and can defect to start a rival firm contract enforcement including binding the multinational itself makes the multinational better off outcomes for the host country are more complex depending on mode switches induced by enforcement if enforcement induces the multinational to switch from exporting to local production welfare improves if local production was occurring anyway enforcement may result in the loss of rents to local agents and lower welfare

financial liberalization financial sector development and growth evidence from malaysia abstract the objective of this paper is to examine whether financial development leads to economic growth or vice versa in the small open economy of malaysia using time series data from 1960 to 2001 we conduct cointegration and causality tests to assess the finance growth link by taking the real interest rate and financial repression into account the empirical evidence suggests that financial liberalization through removing the repressionist policies has a favorable effect in stimulating financial sector development financial depth and economic development are positively related but contrary to the conventional findings our results support robinson s view that output growth leads to higher financial depth in the long run

the government spending multiplier in a mis managed liquidity trap i study the impact of a government spending shock in a new keynesian model when monetary policy is set optimally in this framework the economy is at the zero lower bound but expectations are well managed by the central bank as such the multiplier effect of government spending increases on expected inflation is small while the one on output can be larger than one this is consistent with recent empirical evidence on the effects of the 2009 arra

consumption versus expenditure previous authors have documented a dramatic decline in food expenditures at the time of retirement we show that this is matched by an equally dramatic rise in time spent shopping for and preparing meals using a novel data set that collects detailed food diaries for a large cross section of u s households we show that neither the quality nor the quantity of food intake deteriorates with retirement status we also show that unemployed households experience a decline in food expenditure and food consumption commensurate with the impact of job displacement on permanent income these results highlight how direct measures of consumption distinguish between anticipated and unanticipated shocks to income whereas measures of expenditures obscure the distinction
