states and the business cycle abstract we model the us business cycle using a dynamic factor model that identifies common factors underlying fluctuations in state level income and employment growth we find three such common factors each of which is associated with a set of factor loadings that indicate the extent to which each state s economy is related to the national business cycle according to the factor loadings there is a great deal of heterogeneity in the nature of the links between state and national economies in addition to exhibiting geographic patterns the closeness of state economies to the national business cycle is related not only to differences in industry mix but also to non industry variables such as agglomeration and neighbor effects finally we find that the common factors tend to explain large proportions of the total variability in state level business cycles although again there is a great deal of cross state heterogeneity

similarities and convergence in g 7 cycles this paper examines the properties of g 7 cycles using a multicountry bayesian panel var model with time variations unit specific dynamics and cross country interdependences we demonstrate the presence of a significant world cycle and show that country specific indicators play a much smaller role we detect di erences across business cycle phases but apart from an increase in synchronicity in the late 1990s find little evidence of major structural changes we also find no evidence of the existence of an euro area specific cycle or of its emergence in the 1990s

inefficient credit booms this paper studies the welfare properties of competitive equilibria in an economy with financial frictions hit by aggregate shocks in particular it shows that competitive financial contracts can result in excessive borrowing ex ante and excessive volatility ex post even though from a first best perspective the equilibrium always displays under borrowing from a second best point of view excessive borrowing can arise the inefficiency is due to the combination of limited commitment in financial contracts and the fact that asset prices are determined in a spot market this generates a pecuniary externality that is not internalized in private contracts the model provides a framework to evaluate preventive policies which can be used during a credit boom to reduce the expected costs of a financial crisis copyright 2008 wiley blackwell

flexibility and uncertainty the preserving of flexibility when faced with uncertainty is a neglected aspect of behaviour under risk yet it is an important factor in decisions to hold liquid assets or delay irreversible investment this paper formalizes the notion of flexibility in a sequential decision context and relates its value to the amount of information an agent expects to receive a rudimentary money demand model is developed embodying these ideas and the history of flexibility as an economic concept is traced choices are frequently made between alternatives that imply different degrees of future commitment between a short term investment that leaves future options open for example and a long term one that by its very nature forecloses those options the relative attractiveness of the two depends on their probability distributions of payoffs over time a basic consideration in this choice is the recognition that beliefs about the risks governing these payoffs may change current doubts may be partially resolved in the near future this prospect decreases the attractiveness of the longer term commitment in that one is able to respond less fully to new information and even if it does not directly affect the risks associated with shorter term choices enhances their appeal this paper formalizes the above remarks by establishing connections between the following two partial orderings the first is an ordering based on variability of beliefs one set of beliefs is more variable than another if more final risk is resolved at an intermediate stage the more one expects to learn by an intermediate period relative to what one knows today the more variation one is anticipating in beliefs about the final outcome the second is an ordering of current actions or positions based on flexibility one position is more flexible than another if it leaves available a larger set of future positions at any given level of cost these two orderings are incorporated in a simple sequential decision model to suggest the following behavioural principle the more variable are a decision maker s beliefs the more flexible is the position he will choose this principle potentially applies whenever i there will be opportunities to act after further information is received and ii current actions influence either the attractiveness or availability of different future actions

risk sharing by households within and across regions and industries abstract cochrane 1991 journal of political economy 99 957 976 and mace 1991 journal of political economy 99 928 956 test if risk sharing across households is complete in the sense that household consumption moves one for one with aggregate consumption in their studies the source of income risk is idiosyncratic and agents can share risk across the entire economy using a sample of households from the panel study on income dynamics psid we explore whether households share the risk associated with their industries and regions across households in other regions and industries we find that a large fraction of risk faced by households is not shared across regions and industries

bank risk taking securitization supervision and low interest rates evidence from the euro area and the u s lending standards using a unique dataset of the euro area and the u s bank lending standards we find that low monetary policy short term interest rates soften standards for household and corporate loans this softening especially for mortgages is amplified by securitization activity weak supervision for bank capital and low monetary policy rates for an extended period conversely low long term interest rates do not soften lending standards finally countries with softer lending standards before the crisis related to negative taylor rule residuals experienced a worse economic performance afterward these results help shed light on the origins of the crisis and have important policy implications the author 2011 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press

the risk taking channel of monetary policy exploring all avenues the literature on the risk taking channel of monetary policy grew quickly leading to scattered evidence we examine this channel through different angles exploring detailed information on loan origination and performance ex ante riskier borrowers receive more funding at the extensive margin when interest rates are lower ex post performance is independent of the level of interest rates at origination still loans granted in periods of very low and stable interest rates show higher default rates once interest rates start to increase risk taking is stronger among banks with lower capital ratios suggesting that this channel may be linked to managerial incentives for risk shifting

the correlation of productivity growth across regions and industries in the united states abstract this paper shows that productivity growth is more strongly correlated across u s regions than across the g7 countries cross region correlations of productivity growth within a given industry are typically stronger than cross sector correlations of productivity growth within the same region

supply capacity acquisition and allocation with uncertain customer demands we study a class of capacity acquisition and assignment problems with stochastic customer demands often found in operations planning contexts in this setting a supplier utilizes a set of distinct facilities to satisfy the demands of different customers or markets our model simultaneously assigns customers to each facility and determines the best capacity level to operate or install at each facility we propose a branch and price solution approach for this new class of stochastic assignment and capacity planning problems for problem instances in which capacity levels must fall between some pre specified limits we offer a tailored solution approach that reduces solution time by nearly 80 over an alternative approach using a combination of commercial nonlinear optimization solvers we have also developed a heuristic solution approach that consistently provides optimal or near optimal solutions where solutions within 0 01 of optimality are found on average without requiring a nonlinear optimization solver

tastes and technology in a two country model of the business cycle explaining international trade on international financial markets allows people to insure country specific risk and smooth consumption intertemporally equilibrium models of business cycles with trade on global financial markets typically yield international consumption correlations near one and excessive volatility of investment the authors incorporate nontraded goods in the model and find that the implications for aggregate consumption investment and the trade balance are consistent with business cycle properties of industrialized countries however the model driven by technology shocks alone yields counterfactual implications for comovements between consumption and prices at the sectoral level taste shocks produce price quantity relationships more consistent with the data copyright 1995 by american economic association

the propagation of regional recessions this paper develops a framework for inferring common markov switching components in a panel data set with large cross section and time series dimensions we apply the framework to studying similarities and dierences across u s states in the timing of business cycles we hypothesize that there exists a small number of cluster designations with individual states in a given cluster sharing certain business cycle characteristics we nd that although oil producing and agricultural states can sometimes experience a separate recession from the rest of the united states for the most part dierences across states appear to be a matter of timing with some states entering recession or recovering before others jel c11 c32 e32

the allocation of credit and financial collapse this paper examines the allocation of credit in a market in which borrowers have greater information concerning their own riskiness than do lenders it illustrates that 1 the allocation of credit is inefficient and at times can be improved by government intervention and 2 small changes in the exogenous risk free interest rate can cause large discontinuous changes in the allocation of credit and the efficiency of the market equilibrium these conclusions suggests a role for government as the lender of last resort

age effects leverage and firm growth abstract recent theories of firm dynamics emphasize the role of financial variables as determinants of firm growth empirically examining these relationships has been difficult since there is a lack of financial data on the small young and private firms using a unique administrative data set this paper considers the growth of new firms in canadian manufacturing from a financial perspective we find that financial factors such as leverage and initial financial size impact growth rates for new firms further the inclusion of leverage has little impact on the economic significance of the conditional age and size relationships with firm growth

multi resource investment strategies operational hedging under demand uncertainty abstract consider a firm that markets multiple products each manufactured using several resources representing various types of capital and labor and a linear production technology the firm faces uncertain product demand and has the option to dynamically readjust its resource investment levels thereby changing the capacities of its linear manufacturing process the cost to adjust a resource level either up or down is assumed to be linear the model developed here explicitly incorporates both capacity investment decisions and production decisions and is general enough to include reversible and irreversible investment the product demand vectors for successive periods are assumed to be independent and identically distributed the optimal investment strategy is determined with a multi dimensional newsvendor model using demand distributions a technology matrix prices product contribution margins and marginal investment costs our analysis highlights an important conceptual distinction between deterministic and stochastic environments the optimal investment strategy in our stochastic model typically involves some degree of capacity imbalance which can never be optimal when demand is known

single period multiproduct inventory models with substitution we study a single period multiproduct inventory problem with substitution and proportional costs and revenues we consider n products and n demand classes with full downward substitution i e excess demand for class i can be satisfied using product j for i j we first discuss a two stage profit maximization formulation for the multiproduct substitution problem we show that a greedy allocation policy is optimal we use this to write the expected profits and its first partials explicitly this in turn enables us to prove additional properties of the profit function and several interesting properties of the optimal solution in a limited computational study using two products we illustrate the benefits of solving for the optimal quantities when substitution is considered at the ordering stage over similar computations without considering substitution while ordering specifically we show that the benefits are higher with high demand variability low substitution cost low profit margins or low price to cost ratio high salvage values and similarity of products in terms of prices and costs

pricing and the news vendor problem a review with extensions in the newsvendor problem a decision maker facing random demand for a perishable product decides how much of it to stock for a single selling period this simple problem with its intuitively appealing solution is a crucial building block of stochastic inventory theory which comprises a vast literature focusing on operational efficiency typically in this literature market parameters such as demand and selling price are exogenous however incorporating these factors into the mode l can provide an excellent vehicle for examining how operational problems interact with marketing issues to influence decision making at the firm level in this paper we examine an extension of the newsvendor problem in which stocking quantity and selling price are set simultaneously we provide a comprehensive review that synthesizes existing results for the single period problem and develop additional results to enrich the existing knowledge base we also review and develop insight into a dynamic inventory extension of this problem and motivate the applicability of such models

firm and product life cycles and firm survival on average roughly 5 10 percent of the firms in a given market leave that market over the span of a single year at least so data for a broad range of industries in several economies tell us what is it other than random shocks that determines the probability of survival for a firm in a given market we start by decomposing the forces that affect survival into industry and firm attributes industry attributes we hypothesize encompass variables that exert their influence both over time and across markets the variables that operate over time are defined by the life cycle of the industry life cycles of the industry affect mainly the characteristics of demand and the rate and form of technical change variations across firms we hypothesize arise mainly from learning by doing darwinian survival of the fittest and the obsolescence of initial endowments these variables are linked to the life cycle of the firm how these industry and firm life cycles define patterns of survival is the story

investment and capacity choice under uncertain demand this paper extends the real options literature by discussing an investment problem where a firm has to determine optimal investment timing and optimal capacity choice at the same time under conditions of irreversible investment expenditures and uncertainty in future demand after the project is installed with a certain maximum capacity this capacity is fixed as an upper boundary to the output and cannot be adjusted later on it turns out that in the framework of this once and for all decision uncertainty in future demand leads to an increase in optimal installed capacity but on the other hand it causes investment to be delayed to an extent that even small uncertainty makes waiting and accumulation of further information the optimal decision for large ranges of demand limiting the capacity which may be installed weakens this extreme effect of uncertainty

dynamic capacity planning using strategic slack valuation in this paper we analyze a particular aspect of capacity planning that is concerned with the active trading of production facilities for a homogenous product market we provide a theoretical rationale for the valuation and trading of these assets based on a metric of strategic slack we show that trading production assets with non additive portfolio profitability involves complex coordination with multiple equilibria and that these equilibria depend on the foresight in the planning horizon using the concept of strategic slack we have analyzed the dynamics of market structure the impact of asset trading on the level of production of the industry and to derive boundaries on the value of the traded assets moreover through computational learning the formulation is applied to a large oligopolistic electricity market showing that plant trading tends to lead to increased market concentration high prices lower production and a decrease in consumer surplus

optimal investment strategies for flexible resources considering pricing and correlated demands we study the optimal resource investment decision faced by a two product price setting firm that operates in a monopolistic setting and employs a postponed pricing scheme the firm has the option to invest in dedicated resources as well as a more expensive flexible resource that can satisfy both products while the resource investment decision is made under demand uncertainty pricing and resource allocation decisions are postponed to the time when demand curves are realized our analysis provides the structure of the firm s optimal resource investment strategy as a function of demand parameters and investment costs and shows that the flexible resource investment decision follows athreshold policy we also show that it can be optimal for the firm to invest in the flexible resource even when demand patterns are perfectly positively correlated the reason for flexible capacity investment in this case is financial rather than risk pooling on the other hand we show that it can be optimal for the firm not to invest in the flexible resource even when demand patterns are perfectly negatively correlated the flexible resource investment decision in this case depends on the profitability of the two products based on our analysis we provide principles on the firm s optimal resource investment decision

resource flexibility with responsive pricing this article studies two types of flexibility used by firms to better respond to uncertain market conditions resource flexibility and responsive pricing we consider a situation in which a single flexible resource can be used to satisfy two distinct demand classes while the resource capacity must be decided based on uncertain demand functions the resource allocation as well as the pricing decision are made based on the realized demand functions we characterize the effects of two key drivers of flexibility demand variability and demand correlation assuming normally distributed demand curve intercepts demand variability creates opportunity costs and with fixed prices decreases the firm s profit we show that with the additional flexibility gained from responsive pricing the firm can maximize the benefits of favorable demand conditions and mitigate the effects of poor demand conditions ultimately profiting from variability positive demand correlation on the other hand remains undesirable under responsive pricing the optimal capacity of the flexible resource is always increasing in both demand variability and demand correlation this contrasts with the scenarios based on fixed prices highlighting the crucial difference that responsive pricing makes in the management of flexible resources we further quantify the value of flexibility for the firm and its customers by considering as a benchmark a firm relying on two dedicated resources the value of flexibility is most significant if the demand levels are highly variable and negatively correlated in such cases the firm benefits from demand variability due to responsive pricing while facing limited demand risk due to resource flexibility finally we endogenize the input price of the flexible resource by considering the pricing decision of the resource supplier

valuing flexibility as a complex option this paper develops an approach for valuing flexible production systems using contingent claims pricing demand curves for our model s underlying assets output products may be downward sloping in contrast with the standard option pricing assumption also our marginal production exercise costs may be increasing in addition we allow for multiple products and a production capacity constraint these elements of the model result in complex exercise decisions for the contingent claims which comprise the production system s value we illustrate our approach by valuing a flexible system that produces two products which have profit margin functions with stochastic parameters

channels of interstate risk sharing united states 1963 1990 we develop a framework for quantifying the amount of risk sharing among states in the united states and construct data that allow us to decompose the cross sectional variance in gross state product into several components which we refer to as levels of smoothing we find that 39 percent of shocks to gross state product are smoothed by capital markets 13 percent are smoothed by the federal government and 23 percent are smoothed by credit markets the remaining 25 percent are not smoothed we also decompose the federal government smoothing into subcategories taxes transfers and grants to states

discontinuity of output convergence within the united states why has the course changed has the progress of output convergence changed within the united states this article examines the output convergence among u s states for the last five decades by making several improvements over the extant literature by applying a battery of convergence tests designed to capture nonlinear transitional dynamics to real output per worker data i e nominal values deflated by state level price we find that output convergence has not been a feature of the continental united states since the 1970s instead output convergence has proceeded among four subgroups within which constituent states have certain characteristics in common our regression analysis suggests that state level characteristics related to technology and human capital play a crucial role in accounting for the formation and composition of convergence clubs in agreement with the recent theoretical models of growth and development e g aghion et al 2009 gennaioli et al 2013b the level of technology proxied by patents turns out to be a consistently significant determinant even after controlling for endogeneity suggesting that frictions in the diffusion of technology and human capital may have led to clustering of states with different levels of productivity our results therefore cast doubt on the common view that diffusion of knowledge and technology across state borders is frictionless jel o47 o51

interest rates and credit risk this paper explores the effects of shifts in interest rates on corporate leverage and default we develop a dynamic model in which the relationship between firms and their outside financiers is affected by a moral hazard problem and entrepreneurs initial wealth is scarce the link between leverage and default risk comes from the lower incentives of overindebted entrepreneurs to guarantee firm survival the need to finance new investment with outside funding pushes firms leverage ratio above some state contingent target towards which they gradually adjust through earnings retention the dynamic response of leverage and default to interest rate rises and cuts is both asymmetric and heterogeneously distributed across firms both rises and cuts increase the aggregate default rate in the short run however a higher interest rate reduces firms target leverage and hence produces lower default rates in the longer run this helps rationalize some evidence regarding the risk taking channel of monetary policy

entrepreneurial moral hazard and bank monitoring a model of the credit channel abstract this paper develops a model of the choice between bank and market finance by entrepreneurial firms that differ in the value of their net worth the monitoring associated with bank finance ameliorates a moral hazard problem between the entrepreneurs and their lenders the model is used to analyze the different strands of the credit view of the transmission of monetary policy in particular we derive the empirical implications of a broad credit channel and compare them to those obtained when the model is extended to incorporate some elements of the bank lending channel

employment fluctuations in u s regions and industries the roles of national region specific and industry specific shocks this study quantifies the roles of national region specific and industry specific shocks in aggregate employment fluctuations in u s regions and industries variation among the growth rates of major regions and industries is decomposed into unobserved national region and industry specific components the results reject the view that any heterogeneity in regional fluctuations is attributable to differences in industry composition after controlling for industry mix effects roughly 40 of the variance of the cyclical innovation in any region s growth rate is particular to that region in addition region specific shocks appear to propagate across regions over time

are firms underleveraged an examination of the effect of leverage on default probabilities a commonly held view in corporate finance is that firms are less leveraged than they should be given the potentially large tax benefits of debt in this paper i study the effect of firms leverage on default probabilities as represented by the firms ratings using an instrumental variable approach i find that the leverage s effect on ratings is three times stronger than it is if the endogeneity of leverage is ignored this stronger effect results in a higher impact of leverage on the ex ante costs of financial distress which can offset the current estimates of the tax benefits of debt

intranational business cycles in the united states abstract we established a comprehensive set of stylized facts for intranational business cycles across states and regions in the u s notable findings are that the cross correlations of our consumption measure is much less than that for output and the volatility of the real exchange rate between states is much less than that for output these findings are contrasted with the quantity and price anomalies found in international business cycle data additional results for labour and non labour earnings suggest that the observed amount of intratemporal risk sharing is quite limited as compared to that for intertemporal risk sharing

international risk sharing and european monetary unification abstract we explore income and consumption smoothing patterns among european community ec countries and among oecd countries during the period 1966 90 we find that for oecd as well as for ec countries about 40 percent of shocks to gdp are smoothed at the one year frequency with about half the smoothing achieved through national government budget deficits and half by corporate saving at the three year differencing frequency only 25 percent of shocks to gdp are smoothed mainly via government lending and borrowing in the absence of alternative income and consumption smoothing mechanisms the restrictions on budget deficits imposed by the maastricht treaty should be relaxed to allow governments to run large temporary deficits in response to output shocks

the asymmetric effects of monetary policy a nonlinear vector autoregression approach this paper tests for nonlinearity in a standard vector autoregression including output prices and money supply using an estimation strategy that is consistent with a wide range of structural macroeconomic models shocks to the money supply are found to have stronger output effects and weaker price effects when output growth is initially low positive and negative monetary shocks are found to have nearly symmetric effects in addition there is some evidence that shocks of different magnitudes have asymmetric effects these results are consistent with the view that the aggregate supply curve is convex

managing flexible capacity in a make to order environment flexible capacity has been shown to be very effective to hedge against forecast errors at the investment stage in a make to order environment this flexibility can also be used to hedge against variability in customer orders in the short term for that purpose production levels must be adjusted each period to match current demands to give priority to the higher margin product or to satisfy the closest customer however this will result in swings in production inducing larger order variability at upstream suppliers and significantly higher component inventory levels at the manufacturer through a stylized two plant two product capacitated manufacturing setting we show that the performance of the system depends heavily on the allocation mechanism used to assign products to the available capacity although managers would be inclined to give priority to higher margin products or to satisfy customers from their closest production site these practices lead to greater swings in production result in higher operational costs and may reduce profits

borders and nominal exchange rates in risk sharing models of risk sharing predict that relative consumption growth rates are positively related to changes in real exchange rates we investigate this hypothesis using a new multicountry and multiregional data set within countries we find evidence for risk sharing episodes of high relative regional consumption growth are associated with regional real exchange rate depreciation across countries however the association is reversed relative consumption and real exchange rates are negatively correlated we define this reversal as a border effect we find the border effect and show that it accounts for over half of the deviations from full risk sharing since cross border real exchange rates involve different currencies it is natural to ask how much of the border effect is accounted for by movements in exchange rates our measures indicate that a large part of the border effect comes from nominal exchange rate fluctuations we develop a simple open economy model that is consistent with the importance of nominal exchange rate variability in accounting for deviations from cross country risk sharing

understanding the backus smith puzzle it s the nominal exchange rate stupid backus kehoe and kydland bkk 1992 showed that if international capital markets are complete consumption growth correlations across countries should be higher than their corresponding output growth correlations in stark contrast to the theory however in actual data the consumption growth correlation is lower than the output growth correlation by assuming trade imperfections due to non traded goods backus and smith 1993 showed that there is an additional impediment that works to lower the consumption growth correlation while backus and smith s argument was successful in partially explaining the low growth correlation puzzle it contributed to generating another puzzle because the data forcefully showed that consumption growth is negatively correlated with the real exchange rate which is a violation of the theory in this paper by decomposing the real exchange rate growth of the oecd countries into the nominal exchange rate growth and the inflation differential we find that nominal exchange rate movements are the main source for the backus smith puzzle we find that the nominal exchange rate moves counter cyclically with consumption movements which is a violation of the risk sharing theory with non traded goods we also find that the violations are more pronounced when nominal exchange rate changes are larger in absolute value in contrast the negative of bilateral inflation differentials is positively correlated with bilateral consumption movements the latter finding is in accordance with the theory furthermore using intranational data for the united states where the nominal exchange rate is constant the backus smith puzzle disappears although complete risk sharing is rejected

corporate finance and the monetary transmission mechanism we analyze the transmission effects of monetary policy in a general equilibrium model of the financial sector with bank lending and securities markets bank lending is constrained by capital adequacy requirements and asymmetric information adds a cost to outside bank equity capital in our model monetary policy does not affect bank lending through changes in bank liquidity rather it operates through changes in the spread of bank loans over corporate bonds which induce changes in the aggregate composition of financing by firms and in banks equity capital base the model produces multiple equilibria one of which displays all the features of a credit crunch this article is concerned with the monetary transmission mechanism through the financial sector in particular the banking sector and securities markets specifically it analyzes the effects of open market operations on bank lending and securities issues in a real economy by building on recent advances in the microeconomics of banking it provides some underpinnings for the credit view of monetary policy which in its simplest form relies on an exogenously assumed limited substitutability between bank loans and bonds the macroeconomics literature distinguishes between the money view and credit view of monetary policy transmission bernanke and blinder 1988 1992 the money view takes bonds and loans to be perfect substitutes and only allows for the effects of monetary policy on aggregate investment consumption and savings through changes in interest rates the credit view allows for an additional effect on investment and economic activity operating through bank credit supply

dynamic risksharing in the united states and europe abstract we use a panel var model to improve upon the existing methodologies to analyze interregional risksharing and consumption smoothing channels first we endogenize the output process within a more general multi equation framework capturing the dynamic feedback between output and various smoothing channels second in line with dynamic general equilibrium open economy models of risksharing we exploit impulse response functions to trace the role of each smoothing channel over time in the presence of different structural shocks temporary vs permanent and output vs smoothing channels in the application to the us and oecd countries we find different dynamic properties of different smoothing channels we compare our results with the predictions of standard risksharing and consumption theories and tackle some of the puzzles in the literature such as the international risksharing puzzle and the consumption output correlation puzzle we are also able to address such policy issues as whether fiscal stabilizers have been substitutes or complements for financial market diversification activities and whether further financial market integration is likely to provide countries with more shock absorption tools a key result is the strong substitutability between capital and credit smoothing in the us and between fiscal and credit smoothing in the oecd

coordinating the resource investment decision for a two market price setting firm abstract we study the capacity investment decision of a two product firm that is a price setter for both products the products are of varying complexities such that the resource that can be used to produce the higher level product can also be used to produce the lower level one but not vice versa although the firm needs to make its capacity investment decision under demand uncertainty it can utilize this limited downward resource flexibility in addition to pricing to more effectively match its supply with demand as an example consider a firm that owns a main plant satisfying both end product and intermediate product demand and a subsidiary satisfying the intermediate product demand only we formulate this decision problem as a two stage stochastic programming problem with recourse and analyze the impact of coordinated decision making when the resource flexibility is taken into account in the investment decision and demand correlation on the firm s optimal investment strategy our results offer managerial principles on the firm s optimal resource investment strategy

international and intranational business cycles this paper surveys and analyzes the international real business cycle literature we re explore two international business cycle anomalies emphasized by backus kehoe and kydland 1995 as well as establishing the pattern of productivity growth between industries and countries we then compare these findings for the international business cycle to those obtained for data between regions within a country the so called intranational business cycle importantly the intranational business cycle is a natural environment for thinking about the interactions between economies when there are no trade frictions and when there are not multiple currencies we summarize our findings with a comparison between the stylized facts for international and intranational business cycles and draw some policy conclusions copyright 1997 by oxford university press

costly monitoring loan contracts and equilibrium credit rationing this paper develops a model with asymmetrically informed agents and costly monitoring of loan contracts where an equilibrium can exhibit credit rationing borrowers are identical ex ante but some receive loans and others do not in contrast to existing credit rationing theories rationing does not occur here due to inflexible prices adverse selection or moral hazard optimizing behaviour produces a standard debt contract in equilibrium the aggregate quantity of loans and equilibrium interest rates respond differently depending on whether there is rationing in equilibrium

asymmetric shocks among u s states abstract the paper applies a factor model to the study of risk sharing among u s states the factor model makes it possible to disentangle movements in output and consumption due to national regional or state specific business cycles from those due to measurement error the results of the paper suggest that some findings of the previous literature which indicate a substantial amount of inter state risk sharing may be due to the presence of measurement error in output when measurement error is properly taken into account the evidence points towards a lack of inter state smoothing

a theory of financing constraints and firm dynamics there is widespread evidence supporting the conjecture that borrowing constraints have important implications for firm growth and survival in this paper we model a multiperiod borrowing lending relationship with asymmetric information we show that borrowing constraints emerge as a feature of the optimal long term lending contract and that such constraints relax as the value of the borrower s claim to future cash flows increases we also show that the optimal contract has interesting implications for firm dynamics in agreement with the empirical evidence as age and size increase mean and variance of growth decrease and firm survival increases

the declining credit quality of u s corporate debt myth or reality in recent years the number of downgrades in corporate bond ratings has exceeded the number of upgrades leading some to conclude that the credit quality of u s corporate debt has declined however an alternative explanation of this apparent decline in credit quality is that the rating agencies are now using more stringent standards in assigning ratings an ordered probit analysis of a panel of firms from 1978 through 1995 suggests that rating standards have indeed become more stringent implying that at least part of the downward trend in ratings is the result of changing standards bond ratings play a key role in corporate financing and investment decisions a corporation that can issue higher rated bonds usually receives better terms than one that can issue only lower rated bonds by law or policy some investors can purchase only bonds with an investment grade rating a restriction which in some asset pricing models would affect the relative prices of financial assets numerous articles in the popular press have presumed that the credit quality of the debt of u s corporations has been declining over the last couple of decades the comprehensive study by lucas and lonski 1992 of moody s rating changes of corporate debt is consistent with this presumption to cite their statistics in 1970 moody s downgraded 21 issues and upgraded 23 issues but over the following years the number of bonds downgraded began to exceed by substantial margins the number of bonds upgraded and by 1990 moody s downgraded 301 issues and upgraded only 61 their study includes both investment and noninvestment grade bonds but internal data from donaldson lufkin jenrette confirm that this trend also applies to investment grade bonds alone in a somewhat different context grundy 1997 documents similar trends in the ratings of preferred shares over the 1965 to 1990 period as the credit quality of a firm s corporate debt decreases that firm will face a greater probability of financial distress which at the extreme translates into bankruptcy there is some debate as to the effect of financial dis

one money for europe lessons from the us currency union currency union barry eichengreen the creation of a monetary union in europe is often justified by the desire to reap the full benefits of economic integration the complete removal of capital controls raises a large number of issues the case for free capital mobility is strong but not overwhelming it hinges on issues of technology transport costs market structure and labour mobility and in the end is an empirical matter for which us experience may provide useful information policy making institutions differ in important respects however the us tradition of fiscal federalism for example has no ec wide counterpart yet its functions seem a desirable feature of a monetary union in particular it is shown to play an important role in absorbing regional disturbances mostly via the tax system us experience also suggests that a currency union creates pressure for fiscal policy harmonization affecting both taxes and spending although a currency union fundamentally alters the balance of payments adjustment process the potential problem of depressed regions remains a serious one given the increased tightness of the external constraint the limited extent of labour mobility and other features of european labour markets solutions based on us experience include extensive swap facilities and a european version of fiscal federalism

dynamic capacity management with general upgrading this paper studies a capacity management problem with upgrading a firm needs to procure multiple classes of capacities and then allocate the capacities to satisfy multiple classes of customers that arrive over time a general upgrading rule is considered i e unmet demand can be satisfied using multistep upgrade no replenishment is allowed and the firm has to make the allocation decisions without observing future demand we first characterize the structure of the optimal allocation policy which consists of parallel allocation and then sequential rationing specifically the firm first uses capacity to satisfy the same class demand as much as possible then considers possible upgrading decisions in a sequential manner we also propose a heuristic based on certainty equivalence control to solve the problem numerical analysis shows that the heuristic is fast and delivers close to optimal profit for the firm finally we conduct extensive numerical studies to derive insights into the problem it is foun

an inquiry into the sources of macroeconomic fluctuations abstract this paper attempts to decompose the sources of fluctuations in quarterly employment by industry and region into 1 an aggregate national shock 2 region specific shocks 3 industry specific shocks and 4 idiosyncratic factors the empirical analysis is motivated by a dynamic theory of the business cycle the empirical methodology is the engle watson dynamic mimic model implemented via the em algorithm the work is motivated as an attempt to compare empirically aggregate single factor theories of the cycle with real business cycle theories emphasizing industrial or regional shocks

a multi level panel star model for us manufacturing sectors we introduce a multi level smooth transition model for a panel of time series which can be used to examine the presence of common nonlinear business cycle features across many variables the model is positioned in between a fully pooled model which imposes such common features and a fully heterogeneous model which allows for unrestricted nonlinearity we introduce a second stage model linking the parameters that determine the timing of the switches between business cycle regimes to observable explanatory variables thereby allowing for lead lag relationships across panel members we discuss representation estimation by concentrated simulated maximum likelihood and inference we illustrate our model using quarterly industrial production in 19 us manufacturing sectors and document that there are subtle differences across sectors in leads and lags for switches between business cycle recessions and expansions copyright 2005 john wiley sons ltd

optimal investment in product flexible manufacturing capacity this paper presents a model and an analysis of the cost flexibility tradeoffs involved in investing in product flexible manufacturing capacity flexible capacity provides a firm with the ability to respond to a wide variety of future demand outcomes but at the expense of the increased cost of acquiring flexible manufacturing capacity as compared with dedicated or nonflexible capacity we formulate the product flexible manufacturing capacity investment decision as a two stage stochastic program in the first stage the firm must make its investment decision in manufacturing capacity before the resolution of uncertainty in product demand in the second stage after demand for products are known the firm implements its production decisions constrained by the first stage investments the main contributions of this paper are threefold first we develop a model of the firm s flexible manufacturing investment decision that conceptually captures some of the key characteristics of this complex decision probl

global facility network design in the presence of competition abstract we study the facility network design problem for a global firm that is a monopolist seller in its domestic market but faces local competition in its foreign market the global firm produces in the face of demand and exchange rate uncertainty but can postpone localization and distribution of the output until after uncertainties are resolved the competitor in the foreign market however enjoys the flexibility of postponing all production activities until after uncertainties are resolved the two firms engage in an ex post cournot competition in the foreign market we consider three potential network configurations for the global firm under a linear demand function we provide the necessary and sufficient condition that one of the three networks is the global firm s optimal choice and explore how the presence of foreign competition affects the sensitivity of the global firm s design to various cost parameters and market uncertainties

target market selection and marketing effort under uncertainty the selective newsvendor abstract we consider a firm that markets procures and delivers a good with a single selling season in a number of different markets the price for the good is market dependent and each market has an associated demand distribution with parameters that depend on the amount of marketing effort applied given long procurement lead times the firm must decide which markets it will serve prior to procuring the good we develop a profit maximizing model to address the firm s integrated market selection marketing effort and procurement decisions the model implicitly accounts for inventory pooling across markets which reduces safety stock costs but increases model complexity the resulting model is a nonlinear integer optimization problem for which we develop specialized solution methods for the case in which budget constraints exist we provide a novel solution approach that uses a tailored branch and bound algorithm our approach solves a broad range of 3000 test instances in an average of less than 2 seconds significantly outperforming a leading commercial global optimization solver

optimal long term financial contracting we develop an agency model of financial contracting we derive long term debt a line of credit and equity as optimal securities capturing the debt coupon and maturity the interest rate and limits on the credit line inside versus outside equity dividend policy and capital structure dynamics the optimal debt equity ratio is history dependent but debt and credit line terms are independent of the amount financed and in some cases the severity of the agency problem in our model the agent can divert cash flows we also consider settings in which the agent undertakes hidden effort or can control cash flow risk

monetary policy and long run systemic risk taking as an extension to the literature on the risk taking channel of monetary policy this paper studies the existence of a systemic risk taking channel srtc in the eurozone through an original macroeconomic perspective based on causality measures because the srtc is effective after an incubation period we make a distinction between short and long term causality following the methodology proposed by dufour and taamouti 2010 we find that causality from monetary policy to systemic risk while not significant in the very short term robustly represents 75 to 100 of the total dependence between the two variables in the long run reverse causality is rejected systemic risk did not influence the policy of the european central bank before the global financial crisis however central banks must be aware that a too loose monetary policy stance may be conducive to a build up of systemic risk

price versus production postponement capacity and competition this article presents a comparative analysis of possible postponement strategies in a two stage decision model where firms make three decisions capacity investment production inventory quantity and price typically investments are made while the demand curve is uncertain the strategies differ in the timing of the operational decisions relative to the realization of uncertainty we show how competition uncertainty and the timing of operational decisions influence the strategic investment decision of the firm and its value in contrast to production postponement price postponement makes the investment and production inventory decisions relatively insensitive to uncertainty this suggests that managers can make optimal capacity decisions by deterministic reasoning if they have some price flexibility under price postponement additional postponement of production has relatively small incremental value therefore it may be worthwhile to consider flexible ex post pricing before production postponement reengineering while more postponement increases firm value it is counterintuitive that this also makes the optimal capacity decision more sensitive to uncertainty we highlight the different impact of more timely information which leads to higher investment and inventories and of reduced demand uncertainty which decreases investment and inventories our analysis suggests appropriateness conditions for simple make to stock and make to order strategies we also present technical sufficiency and uniqueness conditions under price postponement these results extend to oligopolistic and perfect competition for which pure equilibria are derived interestingly the relative value of operational postponement techniques seems to increase as the industry becomes more competitive

volatility and development why is gdp growth so much more volatile in poor countries than in rich ones we identify four possible reasons i poor countries specialize in more volatile sectors ii poor countries specialize in fewer sectors iii poor countries experience more frequent and more severe aggregate shocks e g from macroeconomic policy and iv poor countries macroeconomic fluctuations are more highly correlated with the shocks of the sectors they specialize in we show how to decompose volatility into these four sources quantify their contribution to aggregate volatility and study how they relate to the stage of development we document the following regularities first as countries develop their productive structure moves from more volatile to less volatile sectors second the level of specialization declines with development at early stages and slowly increases at later stages of development third the volatility of country specific macroeconomic shocks falls with development fourth the covariance between sector specific and country specific shocks does not vary systematically with the level of development we argue that many theories linking volatility and development are not consistent with these findings and suggest new directions for future theoretical work

flexible service capacity optimal investment and the impact of demand correlation we consider a firm that provides multiple services using both specialized and flexible capacity the problem is formulated as a two stage single period stochastic program the firm invests in capacity before the actual demand is known and optimally assigns capacity to customers when demand is realized sample applications include a car rental company s use of mid sized cars to satisfy unexpectedly high demand for compact cars and an airline s use of business class seats to satisfy economy class demand we obtain an analytical solution for a particular case when services may be upgraded by one class the simple form of the solution allows us to compare the optimal capacities explicitly with a solution that does not anticipate flexibility given that demand follows a multivariate normal distribution we analytically characterize the effects of increasing demand correlation on the optimal solution for the case with two customer classes the effects of demand correlation are intuitive increasing correlation induces a shift from flexible to dedicated capacity when there are three or more classes there are also adjustments to the resources not directly affected by the correlation change as correlation rises these changes follow an alternating pattern for example if the optimal capacity of one resource rises then the optimal capacity of the adjacent resource falls these results make precise conjectures based on numerical experiments that have existed in the literature for some time

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

asymmetric effects of positive and negative money supply shocks this paper examines whether positive and negative money supply shocks have symmetric effects on output the results are consistent with the hypothesis that positive money supply shocks do not have an effect on output while negative money supply shocks do have an effect on output this finding is independent of whether or not expected money is assumed to affect output the results reported in this paper imply that the fed could increase the growth rate of real output by reducing the standard deviation of unexpected changes in the money supply

technology investment under flexible capacity strategy with demand uncertainty abstract this paper investigates technology investment under flexible capacity strategy with demand uncertainty technology investment enables a firm to reduce its total production cost while flexible capacity strategy aims to reduce a firm s production waste by postponing production until demand is known adopting a general technology investment cost we examine how technology investment cost structure affects a firm s technology investment decisions we derive the conditions under which the firm will benefit from technology investment we show that the firm can increase its expected profit through technology investment only when the unit technology investment cost that varies inversely with the basic technology level is below a threshold however even though the technology investment cost is zero the benefit from the increase in technology level is limited furthermore we analytically determine the optimal technology levels and establish their relationships under different technology investment cost structures our findings will help firms evaluate various technology investment options and choose the most proper one

market incompleteness and the equity premium puzzle evidence from state level data abstract this paper investigates the importance of market incompleteness by comparing the rates of risk aversion estimated from complete and incomplete markets environments for the incomplete markets case we use consumption data for the 50 us states we find that the rate of risk aversion under the incomplete markets setup is much lower furthermore including the second and third moments of the cross sectional distribution of consumption growth in the pricing kernel lowers the estimate of risk aversion these findings suggest that market incompleteness ought to be seen as an important component of solutions to the equity premium puzzle
