credit constraints equity market liberalizations and international trade abstract this paper provides evidence that credit constraints are an important determinant of international trade flows i exploit shocks to the availability of external finance and examine the impact of equity market liberalizations on the export behavior of 91 countries in the 1980 1997 period i show that liberalizations increase exports disproportionately more in financially vulnerable sectors that require more outside finance or employ fewer collateralizable assets this result is not driven by cross country differences in factor endowments and is independent of simultaneous trade policy reforms moreover it obtains with equal strength in the full panel of countries as well as in both panel and event study analyses of countries which removed capital controls during the sample period finally the effects of liberalizations are more pronounced in economies with initially less active stock markets indicating that foreign equity flows may substitute for an underdeveloped domestic financial system similarly opening equity markets has a greater impact in the presence of higher trade costs caused by restrictive trade policies

the deadweight loss from non neutral capital income taxation abstract this paper develops an overlapping generations general equilibrium model that treats explicitly the role of capital goods in the production process and uses the model to measure the relative magnitudes of different distortions associated with capital income taxation across industries assets and time one of the main results is that uniform capital income taxation is almost certainly suboptimal theoritically but that optimal deviations from uniform taxation are empirically inconsequencial the paper also introduces and applies a general technique for distinguishing intergenerational transfers from efficiency gains in the analysis of the impact of policy changes on long run welfare

measuring the spillovers from technical advance mainframe computers in financial services measuring the social gains from recent technological advances is difficult because there are no output indexes from some important adopters measurement methods that infer the willingness to pay of theadopting industries from the derived demand curve for a new technologyovercome this difficulty the derived demand for high speed computersfor use in banks finance and insurance is shown to imply a very largesocial gain to computerization that is not captured by computer manufacturers copyright 1986 by american economic association

off the cliff and back credit conditions and international trade during the global financial crisis abstract we study the collapse of international trade flows during the global financial crisis using detailed data on monthly us imports we show that credit conditions were an important channel through which the crisis affected trade volumes by exploiting the variation in the cost of capital across countries and over time as well as the variation in financial vulnerability across sectors countries with higher interbank rates and thus tighter credit markets exported less to the us during the peak of the crisis this effect was especially pronounced in sectors that require extensive external financing have limited access to trade credit or have few collateralizable assets exports of financially vulnerable industries were thus more sensitive to the cost of external capital than exports of less vulnerable industries and this sensitivity rose during the financial crisis the quantitative implications of our estimates for trade volumes highlight the large real effects of financial crises and the potential gains from policy intervention

network models and financial stability abstract systemic risk is a key concern for central banks charged with safeguarding overall financial stability in this paper we investigate how systemic risk is affected by the structure of the financial system we construct banking systems that are composed of a number of banks that are connected by interbank linkages we then vary the key parameters that define the structure of the financial system including its level of capitalisation the degree to which banks are connected the size of interbank exposures and the degree of concentration of the system and analyse the influence of these parameters on the likelihood of knock on defaults first we find that the better capitalised banks are the more resilient is the banking system against contagious defaults and this effect is non linear second the effect of the degree of connectivity is non monotonic i e initially a small increase in connectivity increases the contagion effect but after a certain threshold value connectivity improves the ability of a banking system to absorb shocks third the size of interbank liabilities tends to increase the risk of knock on default even if banks hold capital against such exposures fourth more concentrated banking systems are shown to be prone to larger systemic risk all else equal in an extension to the main analysis we study how liquidity effects interact with banking structure to produce a greater chance of systemic breakdown we finally consider how the risk of contagion might depend on the degree of asymmetry tiering inherent in the structure of the banking system a number of our results have important implications for public policy which this paper also draws out

the real effects of financial integration abstract this paper shows how correlations in gdp fluctuations rise with financial integration finance serves to increase international correlations in both consumption and gdp fluctuations which explains the persistent gap between the two in the data a quantity puzzle the positive association between financial integration and gdp correlation constitutes a puzzle as theory suggests a negative relation if anything nevertheless it prevails in the data even after the effects of finance on trade and specialization are accounted for

rational heuristics expectations and behaviors in evolving economies with heterogeneous interacting agents we analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent based model populated by heterogeneous interacting firms agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change imperfect information coordination hurdles and structural breaks in these circumstances we find that neither individual nor macroeconomic dynamics improve when agents replace myopic expectations with less naive learning rules our results suggest that fast and frugal robust heuristics may not be a second best option but rather rational responses in complex and changing macroeconomic environments jel c63 d8 e32 e6 o4

managerial overconfidence in initial public offering decisions and its impact on macrodynamics and financial stability analysis using an agent based model abstract in this study we build a macroeconomic agent based model that is calibrated for the specific case of poland to explore whether the overconfidence of top corporate managers in the context of their initial public offering ipo decisions is detrimental for the firms being managed in this way the financial market dynamics and the selected macroeconomic indicators we found a contradiction between the micro and macro impacts of overconfidence overconfident firms showed better performance in terms of output than other firms but were also more exposed to stock market volatility thereby making them more likely to default the higher default rates of overoptimistic firms negatively impacted the banking sector and increased financial instability finally we ran policy shocks and showed that increased financial instability can be offset by strengthening the regulation of the banking sector

trade credit bank lending and monetary policy transmission this paper investigates the role of trade credit in the transmission of monetary policy most models of the transmission mechanism allow the firm to access only financial markets or bank lending according to some net worth criterion in our model we introduce trade credit as an additional source of funding we predict that when monetary policy tightens there will be a reduction in market and bank lending and an increase in trade credit this is confirmed with an empirical investigation of 16 000 manufacturing firms

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

fiscal policy and business cycle characteristics in a heterogeneous agent macro model abstract this paper explores the macroeconomic implications of changing fiscal policy in a heterogeneous interacting agent hia model the key contributions to the existing hia complex adaptive trivial system cats literature include the addition of a progressive income tax structure an expanded role for redistribution and a stylized reactive government sector in certain specifications deficit financed tax cuts are shown to effectively shorten recessions while deficit financed spending stimulus is able to lengthen recoveries alternative specifications provide ambiguous support for generalizing the effectiveness of these policy treatments robustness checks support the general findings that increased redistribution towards the unemployed results in higher unemployment rates greater inequality and shorter contractions

distance constraints the limits of foreign lending in poor economies how far does mobility of multinational banks solve problems of financial development using a panel of 80 000 loans over 7 years i show that greater cultural and geographical distance between a foreign bank s headquarters and local branches leads it to further avoid lending to informationally difficult yet fundamentally sound firms requiring relational contracting greater distance also makes them less likely to bilaterally renegotiate and less successful at recovering defaults differences in bank size legal institutions risk preferences or unobserved borrower heterogeneity cannot explain these results these distance constraints can be large enough to permanently exclude certain sectors of the economy from financing by foreign banks

taxation within cournot oligopoly abstract when the production of output causes pollution we often consider taxation as a means to reduce it this paper examines various forms of taxation to control pollution within cournot oligopoly it shows that two commonly used forms can actually increase pollution in contrast both of these forms unambiguously reduce pollution within the competitive model the paper provides conditions in terms of demand and technology that make taxation effective in the cournot oligopoly case another implication of the analysis is that outside the price taking framework asymmetry of cost functions is particularly important and deserves careful attention when we examine the effect of taxation

rents and the cost and optimal design of commodity taxes this paper numerically investigates the significance of rents for both the welfare costs and the optimal design of commodity taxes using a general equilibrium model calibrated to 1986 canadian data in the data we use ricardian rents are concentrated in agriculture and utilities with market structure rents concentrated in manufacturing different types of rents have different implications for the welfare cost of taxes and hence also for appropriate tax design ricardian rents lower the cost of taxes rents supported by imperfect competition with no free entry raise the cost of taxes rents supported by regulation generate rent seeking costs and if taxed improve resource allocation model results show a markedly nonuniform optimal tax structure and a substantial influence of the treatment of rents on the pattern of optimal tax rates by commodity

bank linkages and international trade abstract we uncover a new channel through which international finance is related to trade the formation of international bank linkages increases exports bank linkages are measured for each pair of countries in each year as a number of bank pairs in these two countries that are connected through cross border syndicated lending using a gravity approach to model trade for 66 countries over 24 years with a full set of fixed effects source year target year source target we find that new connections between banks in a given country pair lead to an increase in trade flows between these countries in the following year and to trade diversions from countries competing for similar imports we conjecture that the mechanism for this effect is the role bank linkages play in reducing export risk and present evidence supporting this conjecture in particular using industry level trade data and controlling for country pair year and industry fixed effects we find that new bank linkages have larger impacts on trade in industries which tend to be subject to more export risk for u s banks we can show that bank linkages are positively associated with foreign letter of credit exposures

tax evasion and the optimum general income tax abstract this paper incorporates tax evasion into an optimum general income tax problem with endogenous labor supply it posits a two group model with high and low wage individuals to investigate the properties of optimal audit and tax structures the following main results are obtained first high wage persons are never audited while low wage persons are audited with a probability strictly less than one secondly high wage persons should face a zero marginal tax rate thirdly low wage individuals who have been audited and found innocent should pay a lower tax than those who are not audited fourthly there are two possible tax regimes low wage persons face a positive marginal tax rate under one regime and a zero rate under the other fifthly even if honesty cannot be rewarded the other results of the paper continue to hold

insecurity and the pattern of trade an empirical investigation corruption and imperfect contract enforcement dramatically reduce international trade this paper estimates the reduction using a structural model of import demand in which insecurity acts as a hidden tax on trade we find that inadequate institutions constrain trade as much as tariffs do we also find that omission of indices of institutional quality biases the estimates of typical gravity models obscuring a negative relationship between per capita income and the share of total expenditure devoted to traded goods finally we argue that cross country variation in the effectiveness of institutions and the consequent variation in the prices of traded goods offer a simple explanation for the stylized fact that high income capital abundant countries trade disproportionately with each other

international shock transmission after the lehman brothers collapse evidence from syndicated lending after lehman brothers filed for bankruptcy in september 2008 cross border bank lending contracted sharply to explain the severity and variation in this contraction we analyze detailed data on cross border syndicated lending by 75 banks to 59 countries we find that banks that had to write down sub prime assets refinance large amounts of long term debt and experienced sharp declines in their market to book ratio transmitted these shocks across borders by curtailing their lending abroad while shocked banks differentiated between countries in much the same way as less constrained banks they restricted their lending more to small borrowers

trade credit and the bank lending channel the bank lending channel theory posits that during monetary contractions banks restrict some firms loans thus reducing their desired investment independently of interest rates previous research finds small firms reduce while large firms accelerate loan growth we find that small firms increase trade credit a substitute credit indicating a strong loan demand it supports the bank lending channel they do not voluntarily cut bank loans since they increase a less desirable alternative using trade credit is propitious since unlike commercial paper investigated by previous researchers it is widely used by the small firms suffering the loan decline surprisingly we also find large firms increase trade credit a puzzle since they are typically assumed to have wide access to other credit using individual manufacturing firm data we find the reasons large firms use trade credit are financial in nature those without a bond rating increase trade credit that is without access to open market credit as relatively few firms have this mark of quality it implies that more firms are affected by credit constraints than previously believed

us trade and inventory dynamics we examine the source of the large fall and rebound in us trade in the recent recession while trade fell and rebounded more than expenditures or production of traded goods we find that relative to the magnitude of the downturn these trade fluctuations were in line with those in previous business cycle fluctuations we argue that the high volatility of trade is attributed to more severe inventory management considerations of firms involved in international trade we present empirical evidence for autos as well as at the aggregate level that the adjustment of inventory holdings help explain these fluctuations in trade

taxation and welfare in an oligopoly with strategic commitment this paper establishes comparative statics results for an oligopoly model with strategic commitment firms compete in two stages in the first stage firms decide on strategic cost reducing r d investment whereas they choose output in the second stage taking an excise tax subsidy as a shift parameter in the second stage game the short run as well as long run effects on output cost reducing r d investment and second best welfare will be examined the crucial role played by the strategic substitutability of outputs as well as cost reducing r d investments is clarified and a variant of the le chatelier samuelson principle in the authors game theoretic model is obtained copyright 1992 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

financial crises and the composition of cross border lending abstract we examine the composition and drivers of cross border bank lending between 1995 and 2012 distinguishing between syndicated and non syndicated loans we show that on balance sheet syndicated loan exposures which account for almost one third of total cross border loan exposures increased during the global financial crisis due to large drawdowns on credit lines extended before the crisis our empirical analysis of the drivers of cross border loan exposures in a large bilateral dataset leads to three main results first banks with lower levels of capital favor syndicated over other kinds of cross border loans second borrower country characteristics such as level of development economic size and capital account openness are less important in driving syndicated than non syndicated loan activity suggesting a diversification motive for syndication third information asymmetries between lender and borrower countries became more binding for both types of cross border lending activity during the recent crisis

are output growth rate distributions fat tailed some evidence from oecd countries this work explores some distributional properties of aggregate output growth rate time series we show that in the majority of oecd countries output growth rate distributions are well approximated by symmetric exponential power densities with tails much fatter than those of a gaussian fat tails robustly emerge in output growth rates independently of i the way we measure aggregate output ii the family of densities employed in the estimation iii the length of time lags used to compute growth rates we also show that fat tails still characterize output growth rate distributions even after one washes away outliers autocorrelation and heteroscedasticity

inequality household debt and financial instability an agent based perspective abstract our paper contributes to the literature on the causes of the 2007 2008 financial crisis in the united states by means of an agent based model we replicate an artificial credit network economy in order to assess the impact of growing income inequality in the presence of peer effects and home equity borrowing we show that the resulting debt financed consumption boom jeopardises the stability of the economic system thus paving the way for a financial crisis our model includes a behavioural rule for consumption based on expenditure cascades a hierarchical structure of household finance an articulated credit market with collateralised consumption loans and mortgages and a simple housing market results show that the model is able to capture the economic and social pressure of inequality on low and middle income households that pushes them to increase their consumption via home equity extraction rising non performing loans lead to higher bad debt on the banks balance sheets and consequently to the emergence of a crisis as an endogenous dynamic

why are distributions of firm growth rates tent shaped abstract recent empirical analyses on different datasets have revealed a common exponential behavior in the shape of the probability density of the corporate growth rates we present new evidence on this topic from the italian manufacturing industry and propose a very simple mechanism that under rather general assumptions provides a robust explanation for the observed regularities

a new approach to business fluctuations heterogeneous interacting agents scaling laws and financial fragility abstract in this paper we discuss a scaling approach to business fluctuations our starting point consists in recognizing that concepts and methods derived from physics have allowed economists to re discover a set of stylized facts which have to be satisfactorily accounted for in their models standard macroeconomics based on a reductionist approach centered on the representative agent is definitely badly equipped for this task on the contrary we show that a simple financial fragility agent based model based on complex interactions of heterogeneous agents is able to replicate a large number of scaling type stylized facts with a remarkable high degree of statistical precision

optimal non linear health insurance abstract most theoretical and empirical work on efficient health insurance has been based on models with linear insurance schedules a constant co insurance parameter in this paper dynamic optimization techniques are used to analyse the properties of optimal non linear insurance schedules in a model similar to one originally considered by spence and zeckhauser american economic review 1971 61 380 387 and reminiscent of those that have been used in the literature on optimal income taxation the results of a preliminary numerical example suggest that the welfare losses from the implicit subsidy to employer financed health insurance under us tax law may be a good deal smaller than previously estimated using linear models

trade law and product complexity abstract how does the quality of national institutions that enforce the rule of law influence international trade anderson and marcouiller argue that bad institutions located in the importer s country deter international trade because they enable economic predators to steal and extort rents at the importer s border we complement this research and show how good institutions located in the exporter s country enhance international trade in particular trade in complex products whose characteristics are difficult to fully specify in a contract we argue that both exporter and importer institutions affect international as well as domestic transaction costs in complex and simple product markets international transaction costs are a part of the costs of trade domestic transaction costs affect complex and simple products differently thereby changing a country s comparative advantage in producing such goods we find ample empirical evidence for these predictions countries that have good institutions tend to

the financial accelerator in an evolving credit network we model a credit network characterized by credit relationships connecting i downstream d and upstream u firms and ii firms and banks the net worth of d firms is the driver of fluctuations the production of d firms and of their suppliers u firms in fact is constrained by the availability of internal finance proxied by net worth to the d firms the structure of credit interlinkages changes over time due to an endogeneous process of partner selection which leads to the polarization of the network at the aggregate level the distribution of growth rates exhibits negative skewness and excess kurtosis when a shock hits the macroeconomy or a significant group of agents in the credit network a bankruptcy avalanche can follow if agents leverage is critically high in a nutshell we want to explore the properties of a network based financial accelerator

the rational nonpurchase of long term care insurance only a tiny fraction of the nonpoor population currently purchases private insurance coverage against long term care ltc costs studies generally attribute the failure to purchase private coverage to unawareness by potential purchasers of the benefits of coverage and a misperception that medicare currently covers long term care i explore alternative reasons for failure to purchase coverage by well informed expected utility maximizing risk averse individuals for whom ltc is associated with a large increase in mortality and for whom family members represent an alternative source of care there may be no demand for ltc insurance even if it is made available at actuarially fair premiums because the main consequence of coverage is to enhance the expected value of one s estate

liaisons dangereuses increasing connectivity risk sharing and systemic risk the recent financial crisis poses the challenge to understand how systemic risk arises endogenously and what architecture can make the financial system more resilient to global crises this paper shows that a financial network can be most resilient for intermediate levels of risk diversification and not when this is maximal as generally thought so far this finding holds in the presence of the financial accelerator i e when negative variations in the financial robustness of an agent tend to persist in time because they have adverse effects on the agent s subsequent performance through the reaction of the agent s counterparties 2012 elsevier b v all rights reserved

foreign banks trends and impact over the past two decades foreign banks have become much more important in domestic financial intermediation heightening the need to understand their behavior we introduce a new comprehensive database made publicly available on bank ownership including the home country of foreign banks for 5 324 banks in 137 countries over the period 1995 2009 we document large increases in foreign bank presence in many countries but with substantial heterogeneity in terms of host and banks home countries bilateral investment patterns and bank characteristics in terms of impact we document that the relation between private credit and foreign bank presence importantly depends on host country and banks characteristics specifically foreign banks only seem to have a negative impact on credit in low income countries in countries where they have a limited market share where enforcing contracts is costly and where credit information is limited available and when they come from distant home countries this shows that accounting for heterogeneity including bilateral ownership is crucial to better understand the implications of foreign bank ownership

the price effects of monetary shocks in a network economy abstract empirical evidence shows monetary shocks have two temporary effects on the distribution of prices one the dispersion of cross section of prices increases in response to monetary shocks two some prices change in the wrong direction some prices decrease in response to positive monetary shocks and increase in response to negative monetary shocks we present a model that generates the two effects of monetary shocks on the distribution of prices as an out of equilibrium phenomena firms are related to each other through a production network monetary shocks change the working capital of a subset of firms and percolate to other firms through buyer seller linkages price dispersion increases because the percolation of a monetary shock through the production network causes prices to differentially deviate from their steady state values some prices change in the wrong direction because a shift in one firm s demand causes a shift in another firm s supply and vice versa thereby generating complicated chains of bi directional price changes monetary shocks can significantly disturb relative prices even when all prices are fully flexible

optimal reimbursement health insurance and the theory of ramsey taxation this paper explores the trade off between risk sharing and the incentives to consume increased medical care inherent in reimbursement insurance the results for the theory of reimbursement insurance are compared with those on ramsey taxation it is shown that there is a close formal analogy and interpretations are given

global banks and crisis transmission abstract we study the effect of financial integration through banks on the transmission of international business cycles in a sample of 18 20 developed countries between 1978 and 2009 we find that in periods without financial crises increases in bilateral banking linkages are associated with more divergent output cycles this relation is significantly weaker during financial turmoil periods suggesting that financial crises induce co movement among more financially integrated countries we also show that countries with stronger direct and indirect financial ties to the u s experienced more synchronized cycles with the u s during the recent 2007 2009 crisis we then interpret these findings using a simple general equilibrium model of international business cycles with banks and shocks to banking activity the model suggests that the relation between integration and synchronization depends on the type of shocks hitting the world economy and that shocks to global banks played an important role in triggering and spreading the 2007 2009 crisis

credit chains and bankruptcy propagation in production networks abstract we present a simple model of a production network in which firms are linked by supplier customer relationships involving extension of trade credit our aim is to identify the minimal set of mechanisms which reproduce qualitatively the main stylized facts of industrial demography such as firms size distribution and at the same time the correlation over time and across firms of output growth and bankruptcies the behavior of aggregate variables can be traced back to the direct firm firm interdependence in this paper we assume that the number of firms is constant and the network has a periodic static structure but the framework allows further extensions to investigate which network structures are more robust against domino effects and if the network is let to evolve in time which structures emerge spontaneously depending on the individual strategies for orders and delivery

financial networks and contagion we study cascades of failures in a network of interdependent financial organizations how discontinuous changes in asset values e g defaults and shutdowns trigger further failures and how this depends on network structure integration greater dependence on counterparties and diversification more counterparties per organization have different nonmonotonic effects on the extent of cascades diversification connects the network initially permitting cascades to travel but as it increases further organizations are better insured against one another s failures integration also faces trade offs increased dependence on other organizations versus less sensitivity to own investments finally we illustrate the model with data on european debt cross holdings jel d85 f15 f34 f36 f65 g15 g32 g33 g38 globalization brings with it increased financial interdependencies among many kinds of organizations governments central banks investment banks firms etc that hold each other s shares debts and other obligations such interdependencies can lead to cascading defaults and failures which are often avoided through massive bailouts of institutions deemed too big to fail recent examples include the us government s interventions in aig fannie mae freddie mac and general motors and the european commission s interventions in greece and spain although such bailouts circumvent the widespread failures that were more prevalent in the nineteenth and early twentieth centuries they emphasize the need to study the risks created by a network of interdependencies understanding these risks is crucial to designing incentives and regulatory responses which defuse cascades before they are imminent in this paper we develop a general model that produces new insights regarding financial contagions and cascades of failures among organizations linked through a network of financial interdependencies organizations values depend on each other e g through cross holdings of shares debt or other liabilities if an

leveraged network based financial accelerator abstract in this paper we build on the network based financial accelerator model of delli gatti et al 2010 modelling the firms financial structure following the dynamic trade off theory instead of the packing order theory moreover we allow for multiperiodal debt structure and consider multiple bank firm links based on a myopic preferred partner choice in case of default we also consider the loss given default rate lgdr we find many results i if leverage increases the economy is riskier ii a higher leverage pro cyclicality has a destabilizing effect iii a pro cyclical leverage weakens the monetary policy effect iv a central bank that wants to increase the interest rate should previously check if the banking system is well capitalized v an increase of the reserve coefficient has an impact similar to that produced by raising the policy rate but for the enlargement of bank reserves that improves the resilience of the banking system to shocks

the design of long term care insurance contracts this paper studies the design of long term care ltc insurance contracts in the presence of ex post moral hazard while this problem bears some similarity with the study of health insurance blomqvist 1997 the significance of informal ltc affects the problem in several crucial ways it introduces the potential crowding out of informal care by market care financed through insurance coverage furthermore the information structure becomes more intricate informal care is not publicly observable and unlike the insurer caregivers know the true needs of their relatives we determine the optimal second best contract and show that the optimal reimbursement rate can be written as an a b c expression a la diamond 1998 these terms respectively reflect the efficiency loss as measured by the inverse of the demand elasticity the distribution of needs and the preferences for risk sharing interestingly informal care directly affects only the first term more precisely the first term decreases with the presence and significance of informal care roughly speaking this means that an efficient ltc insurance contract should offer lower marginal reimbursement rates than its counterpart in a health insurance context

trade finance and the great trade collapse pieces of evidence that support the trade finance channel first we show that export prices rose relative to domestic manufacturing prices across a large number of countries second we find that import and export prices of goods shipped by sea which are likely to be affected most by trade finance contractions rose disproportion ately more than those shipped by air or land

loan syndication and credit cycles cyclicality in the supply of business credit has been the focus of a considerable amount of research this cyclicality can stem from shocks to borrowers collateral which affect firms ability to raise capital if agency and information problems are significant ben s bernanke and mark gertler 1989 or it can stem from shocks to bank capital which affect the supply of bank loans if agency and information problems limit the ability of banks to raise additional capital bernanke 1983 both of these channels may have been at work during the financial crisis that started in 2007 ran duchin oguzhan ozbas and berk a sensoy 2010 show that firms with more collateral were better able to withstand the contraction in credit and victoria ivashina and david scharfstein 2010 show that reductions in bank capital had an adverse effect on lending in this paper we examine cyclicality in the supply of credit in the context of modern forms of banking often referred to as the originateto distribute model in particular we are interested in the role of syndicated lending in traditional bank lending the focus of most models of banking banks originate and hold loans on their balance sheets this exposes banks to risk but provides them with strong incentives to screen and monitor borrowers douglas w diamond 1984 over the last 20 years however the development and growth of the syndicated loan market has enabled a bank to originate a loan but retain only a fraction of it on average the originating bank or lead bank retains about a third of each syndicated loan and sells the remaining share to a syndicate of investors which includes banks and institutional investors such as pension funds mutual funds hedge funds and sponsors of structured loan syndication and credit cycles

between scylla and charybdis income distribution consumer credit and business cycles we introduce a macroeconomic model with heterogeneous households and an aggregate banking sector in order to analyze the impact of rising income inequality under different credit scenarios growing inequality produces debt led consumption boom dynamics when the banking sector is characterized by a lower capital requirement and a higher willingness to lend instead when inequality rises but the banking sector is highly regulated aggregate demand and output fall our results also yield new insights on the appropriate fiscal policy reaction to stabilize the economy acting on the progressivity of the tax system seems more effective than a proactive countercyclical fiscal policy jel c63 d31 e62 g01

towards a credit network based early warning indicator for crises this paper presents an agent based model which underlines the importance of credit network and leverage dynamics in determining the resilience of the system defining an early warning indicator for crises the model reproduces macroeconomic dynamics emerging from the interactions of heterogeneous banks and firms in an endogenous credit network banks and firms are linked through multiple credit relations which derive from individual target leverage choices agents choose the more convenient leverage level according to a basic reinforcement learning algorithm simulations are calibrated on balance sheet data of banks and firms quoted in the japanese stock exchange markets from 1980 to 2012

optimal departures from marginal cost pricing focuses on departures from marginal cost pricing optimal allocation or resources level of tax revenue that will be collected by the government theorems developed for resource allocation ebsco

indirect taxation and cournot equilibrium we analyse a cournot model of oligopoly in an industry which is subject to indirect taxation we consider value added as well as excise taxes we allow for various types of demand and cost conditions as well as cost differences across firms as the tax is raised two types of outcomes can prevail on the one hand the net price can increase which is shown to lead to an increase in market share of high cost firms on the other hand the net price can fall in which case efficiency is rewarded in that low cost firms gain market share this latter outcome which accords with intuition will obtain in most instances it is more likely to occur i with vat rather than with an excise tax ii with concave rather than convex demand and iii with decreasing rather than increasing marginal cost finally we show that an increase in vat can lead to higher profits for low cost firms provided cost differences across firms are large enough

minsky from the bottom up formalising the two price model of investment in a simple agent based framework abstract this paper presents a fully formalised version of hyman minsky s two price model of capital investment embedded in a macroeconomic model consisting of an agent based sector of consumption goods firms as well as three strongly simplified aggregated sectors in an innovation to the literature on minsky models the model is calibrated empirically using moments drawn from us data demonstrating that it is capable of producing plausible time series simulations show that the individual investment and financing choices made by the agent based firms lead to the emergence of business cycles at the aggregate level key aspects of the model can be closely related to central concepts from the financial accelerator literature and moreover it is demonstrated through simulation experiments that expectations and sentiment dynamics play an important role being able to amplify or dampen the cycles it is also shown that the introduction of fiscal policy monetary policy or a restriction on firm dividend payouts can contribute to a stabilisation of the model
