consumption and debt response to unanticipated income shocks evidence from a natural experiment in singapore abstract this paper uses a unique panel dataset of consumer financial transactions to study how consumers respond to an exogenous unanticipated income shock consumption rose significantly after th

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

how quantitative easing works evidence on the refinancing channel we document the transmission of large scale asset purchases by the federal reserve to the real economy using rich borrower linked mortgage market data and an identification strategy based on mortgage market segmentation we find that central bank qe1 mbs purchases substantially increased refinancing activity reduced interest payments for refinancing households led to a boom in equity extraction and increased aggregate consumption relative to qe ineligible jumbo mortgages qe eligible conforming mortgage interest rates fell by an additional 40 bp and refinancing volumes increased by an additional 56 during qe1 we estimate that households refinancing during qe1 increased their durable consumption by 12 our results highlight that the transmission of unconventional monetary policy to the real economy depends crucially on the composition of assets purchased and the degree of segmentation in the marke

nonmonetary effects of the financial crisis in propagation of the great depression this paper examines the effects of the financial crisis of the 1930s onthe path of aggregate output during that period our approach is complementary to that of friedman and schwartz who emphasized the monetary impact of the bank failures we focus on non monetary primarily credit related aspects of the financial sector output link and consider the problems of debtors as well as those of the banking system we argue that the financial disruptions of 1930 33 reduced the efficiency of the credit allocation process and that the resulting higher cost and reduced availability of credit acted to depress aggregate demand evidence suggests that effects of this type can help explain the unusual length and depth of the great depression this abstract was borrowed from another version of this item

foreign ownership and corporate income taxation an empirical evaluation abstract foreign ownership allows countries to effectively export part of their corporate tax burden hence countries with high foreign ownership are expected to impose relatively high corporate taxes the findings of this paper suggest that there indeed is an economically significant positive relationship between foreign ownership and tax burdens in europe already significant foreign ownership levels in europe offer an explanation for the absence of a race to the bottom in corporate tax levels

the debt payment to income ratio as an indicator of borrowing constraints evidence from two household surveys liquidity constraints have been proposed as an important explanation for deviations from the rational expectations permanent income hypothesis this paper introduces to the liquidity constraint literature the ratio of a household s debt payments to its disposable personal income the debt service ratio dsr we find that a household with a high dsr is significantly more likely to be turned down for credit than other households also the consumption growth of likely constrained households identified using the dsr along with the liquid asset to income ratio is significantly more sensitive to past income than that of other households confirming the dsr s value in identifying constrained households

consumption housing collateral and the canadian business cycle using bayesian methods we estimate a small open economy model in which consumers face limits to credit determined by the value of their housing stock the purpose of this paper is to quantify the role of collateralized household debt in the canadian business cycle

foreign direct investment intra firm trade and ownership structure abstract asymmetric information about true opportunity cost in trade between a multinational and its foreign affiliate can alleviate the hold up problem in foreign direct investment selling shares in the affiliate to locals is also beneficial because it increases the parent multinational s information rent that is protected from a host government s confiscatory taxation

debt deleveraging and the liquidity trap a fisher minsky koo approach in this paper we present a simple new keynesian style model of debt driven slumps that is situations in which an overhang of debt on the part of some agents who are forced into rapid deleveraging is depressing aggregate demand making some agents debt constrained is a surprisingly powerful assumption fisherian debt deflation the possibility of a liquidity trap the paradox of thrift a keynesiantype multiplier and a rationale for expansionary fiscal policy all emerge naturally from the model we argue that this approach sheds considerable light both on current economic difficulties and on historical episodes including japan s lost decade now in its 18th year and the great depression itself

collusion under asymmetric information when applied to groups the revelation principle postulates a bayesian nash behavior between agents their binding agreements are unenforceable or the principal can prevent them at no cost we analyze instead a mechanism design problem in which the agents can communicate between themselves and collude under asymmetric information we characterize the set of implementable collusion proof contracts both when the principal offers anonymous and nonanonymous contracts after having isolated the nexi and the stakes of collusion we proceed to a normative analysis perform some comparative statics discuss our concept of collusion proofness and provide some insights about transaction costs in side contracting

the principal agent relationship with an informed principal ii common values in many circumstances a principal may have relevant private information when she proposes a contract to an agent we analyze such a principal agent relationship as a noncooperative game the principal proposes a contract which is accepted or rejected by the agent who for most of our analysis has no private information the contract is executed if accepted otherwise the reservation allocation takes effect this allocation may be determined by a pre existing contract which the principal by her proposal is attempting to renegotiate or it may simply be the no trade point in this paper we assume that the principal s information directly affects the agent s payoff before solving the game we discuss pareto efficiency with asymmetric information we define an incentive compatible allocation to be weakly interim efficient wie if there exists no alternative incentive compatible allocation that both parties prefer for all possible beliefs that the agent might have about the principal s private information type we show that any wie allocation is interim efficient ie for some beliefs the rothschild stiglitz wilson rsw allocation relative to the reservation allocation l is the allocation that maximizes the payoff of each type of principal within the class of incentive compatible allocations that guarantee the agent at least the utility he gets from a irrespective of his beliefs about the principal s type the equilibrium set of the contract proposal game consists of the allocations that weakly pareto dominate the rsw allocation thus there is a unique equilibrium outcome if and only if the latter is ie and the equilibrium outcome is the rsw allocation itself after characterizing the equilibrium allocations we study those that are renegotiation proof when either the principal or the agent leads the renegotiation we then compare our contract proposal game which is a signaling model with its screening counterpart we conclude by extending our results to the case in which the agent as well as the principal has private information under the assumption of quasi linear preferences

multiperiod loans occasionally binding constraints and monetary policy a quantitative evaluation we study the implications of multiperiod mortgage loans for monetary policy considering several realistic modifications fixed interest rate contracts a lower bound constraint on newly granted loans and the possibility of the collateral constraint to become slack to an otherwise standard dsge model with housing and financial intermediaries we estimate the model in its nonlinear form and argue that all these features are important to understand the evolution of mortgage debt during the recent us housing market boom and bust we show how the nonlinearities associated with the two constraints make the transmission of monetary policy dependent on the housing cycle with weaker effects observed when house prices are high or start falling sharply we also find that higher average loan duration makes monetary policy less effective and may lead to asymmetric responses to positive and negative monetary shocks

house prices home equity based borrowing and the u s household leverage crisis us household leverage sharply increased in the years preceding the 2007 eco nomic recession the top panel of figure 1 shows the steady rise in household debt since 1975 which accelerated beginning in 2002 in just five years the household sector doubled its debt balance in comparison the contemporaneous increase in corporate debt was modest the middle panel shows that the increase in household debt from 2002 to 2007 translated into a striking rise in household leverage as mea sured by the debt to income ratio during the same time period corporate leverage declined the dramatic absolute and relative rise in us household leverage from 2002 to 2007 is unprecedented compared to the last 25 years one reason for the rapid expansion in household leverage during this period is that mortgage credit became more easily available to new home buyers mian and sufi 2009 strong house price appreciation from 2002 to 2006 however which may have been fueled by the availability of mortgage credit to a riskier set of new home buyers could also have had an important feedback effect on household lever age through existing homeowners given that 65 percent of us households already owned their primary residence before the acceleration in house prices the feedback from house prices to borrowing may be an important source of the rapid rise in household leverage that preceded the economic downturn our central goals in this study are to estimate how homeowner borrowing responded to the increase in house prices and to identify which homeowners responded most aggressively we examine this home equity based borrowing channel using a dataset consisting of anonymous individual credit files of a national consumer credit bureau agency we follow a random sample of over 74 000 us homeowners who owned their homes as of 1997 at an annual frequency from the end of 1997 until the end of 2008 the bottom panel of figure 1 plots the growth in debt of 1997 homeowners over time and shows that existing homeowners borrow significantly more debt as their house prices appreciate from 2002 to 2006 while the aggregate trend is suggestive

housing finance and monetary policy we document three facts concerning how the structure of housing finance affects the monetary transmission mechanism first the characteristics of residential mortgage markets differ markedly across industrialized countries second the impact of monetary policy shocks to residential investment and house prices is significantly stronger in those countries with larger flexibility development of mortgage markets third the transmission to consumption is stronger only in those countries where mortgage equity release is common and mortgage contracts are predominantly of the variable rate type we then build a two sector dsge model with financial constraints to rationalize those facts

interest rates and equity extraction during the housing boom credit record panel data from 1999 2010 indicates that the likelihood of home equity extraction borrowing on average about 40 000 against one s home peaked in 2003 when mortgage rates reached historic lows we estimate a 27 percent rise in extraction in response to a 100 basis point rate decline and that house price growth amplifies this relationship differential responses to interest rates and home price appreciation by borrower age and credit score provide new evidence of financial frictions finally equity extractions are associated with higher default risk consistent with the use of borrowed funds for consumption or illiquid investment

housing dynamics over the business cycle housing construction measured by housing starts leads gdp in a number of countries measured as residential investment the lead is observed only in the united states and canada elsewhere residential investment is coincident variants of existing theory however predict housing construction lagging gdp in all countries in the sample nominal interest rates are low ahead of gdp peaks introducing long term nominal mortgages and an estimated process for nominal interest rates into a standard model aligns the theory with observations on starts as mortgages transmit nominal rates into real housing costs longer time to build makes residential investment cyclically coincident abstract from author

the principal agent relationship with an informed principal the case of private values we analyze the principal agent relationship when the principal has private information as a three stage noncooperative game contract proposal acceptance refusal and contract execution we assume that the information does not directly affect the agent s payoff private values equilibrium exists and is generically locally unique moreover it is pareto optimal for the different types of principal the principal generically does strictly better than when the agent knows her information equilibrium allocations are the walrasian equilibria of an economy where the traders are different types of principal and exchange the slack on the agent s individual rationality and incentive compatibility constraints

when credit bites back using data on 14 advanced countries between 1870 and 2008 we document two key facts of the modern business cycle relative to typical recessions financial crisis recessions are costlier and more credit intensive expansions tend to be followed by deeper recessions in financial crises or otherwise and slower recoveries we use local projection methods to condition on a broad set of macro economic controls to study how past credit accumulation impacts key macro economic variables such as output investment lending interest rates and inflation the facts that we uncover lend support to the idea that financial factors play an important role in the modern business cycle

effects of monetary and macroprudential policies evidence from four inflation targeting economies we examine the effects of monetary and macroprudential policies in the asia pacific region where many inflation targeting economies have adopted macroprudential policies in order to safeguard financial stability using structural panel vector autoregressions that identify both monetary and macroprudential policy actions we show that tighter macroprudential policies used to contain credit growth also have a significant negative impact on macroeconomic aggregates such as real gdp and the price level the similar effects of monetary and macroprudential policies may suggest a complementary use of the two policies at normal times however they could also create challenges for policymakers especially during times when low inflation coincides with buoyant credit growth

household debt and fiscal multipliers we study the size of government spending multipliers in a general equilibrium model with search and matching frictions in which we allow for different levels of household indebtedness the main results are a the presence of impatient households and private debt helps to generate government spending multipliers greater than 1 b as financial conditions worsen the size of the government spending multiplier falls c conversely employment vacancies and unemployment multipliers are larger in a credit crunch d the model explains the observed pattern of responses of labour market variables housing prices and private debt to a fiscal shock reasonably well

interest rate volatility and monetary policy in october 1979 the federal reserve shifted from an interest rate oriented operating procedure to a reserves oriented procedure it is argued in this paper that part of the very large increase in interest rate volatility which resulted from the policy switch may have been due to shifts in the parameters of the money demand equation shifts due to the adoption of a reserve aggregates operating procedure this result is derived by comparing rational expectations equilibria in a simple theoretical model under alternative policy rules this allows the variance of interest rates to be explicitly expressed as a function of the policy rule this abstract was borrowed from another version of this item

one size fits all monetary policy and asymmetric household debt cycles in u s states i investigate the nonlinear effects of monetary policy through differences in household debt across u s states after constructing a novel indicator of inflation for the states i compute state specific monetary policy stances as deviations from an aggregate taylor rule i find that the effectiveness of monetary policy is curtailed during periods of large household debt imbalances moreover a common u s monetary policy does not fit all it may have asymmetric effects on the economic performance across states particularly at times of high dispersion in the household debt imbalances as it may have been the case around the great recession

housing market dynamics and macroprudential policy we perform an analysis to determine how well the introduction of a countercyclical loanto value ltv ratio can reduce household indebtedness and housing price fluctuations compared with a monetary policy rule augmented with house price inflation

is the response of output to monetary policy asymmetric evidence from a regime switching coefficients model this paper investigates regime switching in the response of u s output to a monetary policy action we find substantial statistically significant time variation in this response that corresponds to high response and low response regimes we then investigate whether the timing of the regime shifts are consistent with three particular manifestations of asymmetry by modeling the transition probabilities governing the switching process as functions of state variables we find strong evidence that policy actions taken during recessions have larger effects than those taken during expansions we find less evidence of asymmetry related to the direction or size of the policy action

incentive compatible regulation of a foreign owned subsidiary abstract transfer prices are administered charges for intra firm transfers of factors of production for a multinational firm transfer prices for international transfers provide the means to redistribute costs and increase global profits given variations in national tax and profit repatriation policies local regulation of a subsidiary may thus be necessary to limit the welfare costs of strategic transfer pricing prusa journal of international economics 1990 28 155 172 characterizes the welfare maximizing regulations for a monopoly subsidiary that induce the firm to report transfer prices truthfully we show however that it can be more efficient to implement regulations that encourage the firm to misrepresent its true transfer costs

the effects of tax reform on real estate some empirical results this paper uses data on publicly traded real estate firms to examine the effects of two major tax reforms specifically we analyze the effects of the 1976 and 1986 tax reform acts tras on the risks and returns of real estate investment trusts reits and other real estate firms using intervention analysis since reits have been a dominant force in the real estate equity markets and since they are treated differently for tax purposes than corporations investing in real estate we examine the two groups of firms separately while there exists much popular press literature which discusses the impact of tax reform on real estate little empirical work has directly examined the market s response to these changes 2 most previous work undertaken to examine the potential impact of tax changes has used simulation modeling to estimate the effects on real estate firms values e g fisher and lentz 1986 hendershott follain and ling 1986 a review of the simulation literature is presented in follain and brueckner 1986 turning away from the simulation technique nourse 1987 uses appraisal data to empirically estimate how the 1976 and 1981 tax laws affect capitalization rates i e net income divided by value for real estate in contrast with the existing literature we use market data to evaluate the empirical effects of the 1976 and 1986 law changes the empirical results provide insights into the interaction between tax laws and the market for real estate assets in the next section of the paper we discuss the historical background of the 1976

measuring the impact of fiscal policy in the face of anticipation a structural var approach empirical estimates of the impact of government spending shocks disagree on central issues such as the size of output multipliers and the responses of consumption and the real wage one explanation for the disagreement is that fiscal shocks are often anticipated due to misspecification of the information set anticipation effects may invalidate svar estimates of impulse responses we use economic theory to derive a fiscal svar estimator that is applicable when fiscal shocks are anticipated we study its properties and apply it to us data we fail to find evidence that anticipation effects overturn the existing findings from the fiscal svar literature despite years of intensive research the empirical literature on fiscal policy has yet to reach consensus on the macroeconomic impact of fiscal policy shocks disagreements concern central issues such as the size of output multipliers and the impact of government spending shocks on consumption and the real wage clearly such level of disagreement constrains our ability to give simple guidelines for the operation of one of the most important stabilisation policies a key empirical obstacle is the measurement of innovations to fiscal policy one strand of the literature employs structural vector autoregressive svar methods and achieves identification based on the presence of decision lags or sign restrictions

private debt overhang and the government spending multiplier evidence for the united states using state dependent local projections and historical us data we find that government spending multipliers are considerably larger in periods of private debt overhang in particular while multipliers are below or close to one in low private debt states we find significant crowding in of private spending in periods of debt overhang resulting in multipliers that are much larger than one in high private debt episodes more government purchases even reduce the ratio of government debt to gross domestic product these results are robust for the type of shocks and when we control for the business cycle financial crises deleveraging episodes government debt overhang and the zero lower bound

fixed and variable rate mortgages business cycles and monetary policy the aim of this paper is twofold first i study how the proportion of xed and variable rate mortgages in an economy can aect the way shocks are propagated second i analyze optimal implementable simple monetary policy rules and the welfare implications of this proportion i develop and solve a new keynesian dynamic stochastic general equilibrium model that features a housing market and a group of constrained individuals who need housing collateral to obtain loans a given proportion of constrained households borrows at a variable rate while the rest borrows at a xed rate the model predicts that in an economy with mostly variable rate mortgages an exogenous interest rate shock has larger eects on borrowers than in a xed rate economy aggregate eects are also larger for the variable rate economy for plausible parametrizations dierences are muted by wealth eects on labor supply and by the presence of savers more persistent shocks such as in ation target and technology shocks cause larger aggregate dierences from a normative perspective i nd that in the presence of collateral constraints the optimal taylor rule is less aggressive against in ation than in the standard sticky price model furthermore for given monetary policy a high proportion of xed rate mortgages is welfare enhancing

globalization and the changing logic of collective action globalization transforms collective action in domestic and international politics as the scale of markets widens and as economic organization becomes more complex the institutional scale of political structures can become insufficient for the provision of an appropriate range of public goods a process of this sort occurred prior to the emergence of the modern nation state which itself constituted a paradigmatic response to this predicament today however a complex process of globalization of goods and assets is undermining the effectiveness of state based collective action overlapping playing fields are developing made up of increasingly heterogeneous transnational local and intermediate arenas the residual state retains great cultural force and innovative projects for reinventing government are being tried nevertheless the state s effectiveness as a civil association has eroded significantly and this may lead to a crisis of legitimacy

collusion delegation and supervision with soft information this paper derives an equivalence principle between organizational forms of supervisory and productive activities we consider an organization with an agent privately informed on his productivity and a risk averse supervisor getting signals on the agent s type in a centralized organization the principal can communicate and contract with both the supervisor and the agent however these two agents can collude against the principal in a decentralized organization the principal only communicates and contracts with the supervisor who in turn sub contracts with the agent we show that the two organizations achieve the same outcome we discuss this equivalence and provide various comparative statics results to assess the e ciency of supervisory structures

household debt overhang and transmission of monetary policy we investigate how the level of household indebtedness affects the monetary transmission mechanism in the u s economy using state dependent local projection methods we find that the effects of monetary policy are less powerful during periods of high household debt in particular the impact of monetary policy shocks is smaller on gdp consumption residential investment house prices and household debt during a high debt state we then build a partial equilibrium model of borrower households with financial constraints to rationalize these facts the model points to the weakening of the home equity loan channel as a possible reason for the decline in monetary policy effectiveness when initial debt levels are high

foreign direct investment and host country policies a rationale for using ownership restrictions abstract this paper examines host governments motivation for restricting ownership shares of multinational firms mnfs in foreign direct investment fdi projects an mnf with a productivity advantage is willing to invest in a host country the host government wants to capture the mnf s surplus yet cannot observe it due to the mnf s private information about its firm specific advantage in contrast a joint venture jv partner might observe this surplus depending on its ownership share the host government can alleviate its informational constraints by using ownership restrictions to force a jv this calls into question the wisdom of calls for liberalizing fdi flows by the wholesale elimination of domestic jv requirements we show that the optimal mechanism involves ownership restrictions that decrease as the size of the mnf s firm specific advantage increases

an incentive compatible approach to the transfer pricing problem abstract this paper offers an alternative approach to regulating certain types of transfer pricing if the multinational enterprise s transfer price decision is not regulated it will manipulate the transfer price in order to maximize net global profit traditional approaches argue for ad hoc penalty schedules to mitigate manipulative transfer pricing in contrast this paper offers an incentive compatible approach which explicitly incorporates the informational asymmetries that encourage misreports the model has the desirous feature that the optimal regulatory policy has self enforcing properties that is the firm will find it profit maximizing to report true costs

mortgages and monetary policy mortgages are long term nominal loans under incomplete asset markets monetary policy is shown to affect housing investment and the economy through the cost of new mortgage borrowing and the value of payments on outstanding debt these channels distinct from traditional transmission of monetary policy are evaluated within a general equilibrium model persistent monetary policy shocks resembling the level factor in the nominal yield curve have larger effects than transitory shocks manifesting themselves as long short spread the transmission is stronger under adjustable than fixed rate mortgages higher persistent inflation benefits homeowners under frms but hurts them under arms

macroeconomic effects from government purchases and taxes for u s annual data that include world war ii the estimated multiplier for temporary defense spending is 0 4 0 5 contemporaneously and 0 6 0 7 over 2 years if the change in defense spending is permanent gauged by ramey s defense news variable the multipliers are higher by 0 1 0 2 since all estimated multipliers are significantly less than 1 greater spending crowds out other components of gdp particularly investment the lack of good instruments prevents estimation of reliable multipliers for nondefense purchases multipliers in the literature of two or more likely reflect reverse causation from gdp to nondefense purchases increases in average marginal income tax rates measured by a newly constructed time series have significantly negative effects on gdp when interpreted as a tax multiplier the magnitude is around 1 1 the combination of the estimated spending and tax multipliers implies that the balanced budget multiplier for defense spending is negative we have some evidence that tax changes affect gdp mainly through substitution effects rather than wealth effects

debt and the response to household income shocks validation and application of linked financial account data the increasing availability of data derived from linked consumer financial accounts has the potential to dramatically expand the potential for research examining the most comprehensive existing se

house prices borrowing constraints and monetary policy in the business cycle i develop a general equilibrium model with sticky prices credit constraints nominal loans and asset prices changes in asset prices modify agents borrowing capacity through collateral value changes in nominal prices affect real repayments through debt deflation monetary policy shocks move asset and nominal prices in the same direction and are amplified and propagated over time the financial accelerator is not constant across shocks nominal debt stabilises supply shocks making the economy less volatile when the central bank controls the interest rate i discuss the role of equity debt indexation and household and firm leverage in the propagation mechanism finally i find that monetary policy should not target asset prices as a means of reducing output and inflation volatility

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

leaning against boom bust cycles in credit and housing prices this paper studies the potential gains of monetary and macro prudential policies that lean against house price and credit cycles we rely on a model that features borrowers and savers and allows for over borrowing induced by news shock driven cycles we find that policy that responds to changes in financial variables is socially optimal considering the use of a single policy instrument both types of agents are better off when the interest rate optimally responds to credit growth when we allow for the implementation of both interest rate and ltv policies heterogeneity in the welfare implications is key in determining the optimal use of policy instruments the optimal policy for the borrowers is characterized by a ltv ratio that responds countercyclically to credit growth which most effectively stabilizes credit relative to gdp in contrast the optimal policy for the savers features a constant ltv ratio coupled with an interest rate response to credit growth news shock driven cycles account for most of the gains from a policy response to changes in financial variables

explaining the boom bust cycle in the u s housing market a reverse engineering approach we use a quantitative asset pricing model to reverse engineer the sequences of shocks to housing demand and lending standards needed to replicate the boom bust patterns in u s housing value and mortgage debt from 1993 to 2015 conditional on the observed paths for u s real consumption growth the real mortgage interest rate and the supply of residential fixed assets a specification with random walk expectations outperforms one with rational expectations in plausibly matching the patterns in the data counterfactual simulations show that shocks to housing demand housing supply and lending standards were important but movements in the mortgage interest rate were not

addressing household indebtedness monetary fiscal or macroprudential policy in this paper we build a dynamic stochastic general equilibrium model with housing and household debt and compare the effectiveness of monetary policy housing related fiscal policy and macroprudential regulations in reducing household indebtedness

the financial cycle and macroeconomics what have we learnt abstract it is high time we rediscovered the role of the financial cycle in macroeconomics in the environment that has prevailed for at least three decades now it is not possible to understand business fluctuations and the corresponding analytical and policy challenges without understanding the financial cycle this calls for a rethink of modelling strategies and for significant adjustments to macroeconomic policies this essay highlights the stylised empirical features of the financial cycle conjectures as to what it may take to model it satisfactorily and considers its policy implications in the discussion of policy the essay pays special attention to the bust phase which is less well explored and raises much more controversial issues

macroprudential and monetary policies implications for financial stability and welfare in this paper we analyze the implications of macroprudential and monetary policies for business cycles welfare and financial stability we consider a dynamic stochastic general equilibrium dsge model with housing and collateral constraints a macroprudential rule for the loan to value ratio ltv which responds to credit growth interacts with a traditional taylor rule for monetary policy we compute the optimal parameters of these rules both when monetary and macroprudential policies act in a coordinated and in a non coordinated way we find that both policies acting together unambiguously improves the stability of the system in both cases this interaction is welfare improving for the society especially in the case of the non coordinated game there is though a trade off between borrowers and savers however borrowers can compensate the saver s welfare loss view the mathml sourcela kaldor hicks to achieve a pareto superior outcome

leaning against the credit cycle how should a central bank act to stabilize the ratio of debt over gross domestic product gdp we show how the persistent nature of household debt shapes the answer to this question in environments where households repay mortgages gradually surprise interest hikes only weakly influence household debt and tend to increase debt to gdp in the short run while reducing it in the medium run interest rate rules with a positive weight on debt to gdp cause indeterminacy compared to inflation targeting debt to gdp stabilization calls for a more expansionary policy when debt to gdp is high so as to deflate the debt burden through inflation and output growth

semiparametric estimates of monetary policy effects string theory revisited we develop flexible semiparametric time series methods for the estimation of the causal effect of monetary policy on macroeconomic aggregates our estimator captures the average causal response to discrete policy interventions in a macrodynamic setting without the need for assumptions about the process generating macroeconomic outcomes the proposed estimation strategy based on propensity score weighting easily accommodates asymmetric and nonlinear responses using this estimator we show that monetary tightening has clear effects on the yield curve and on economic activity monetary accommodation however appears to generate less pronounced responses from both estimates for recent financial crisis years display a similarly dampened response to monetary accommodation

macroeconomic effects of the mortgage refinance and the home equity lines of credit abstract i examine how the mortgage refinance and the home equity lines of credit heloc impact the increase in pre crisis mortgage debt and post crisis mortgage defaults financially constrained homeowners can cash out funds through refinancing mortgages or extract home equity through heloc my quantitative exercise shows that prevalent usage of refinancing increases pre crisis mortgage debt which amplifies the post crisis foreclosure rate heloc also contributes to an increase in mortgage defaults though it negligibly impacts pre crisis mortgage debt

regulation asymmetric information and auditing this article analyzes a model of a regulated firm that is better informed about its cost function than is the regulator by auditing at a cost however the regulator is assumed to be able to observe the realized cost of the firm if the regulator finds that the firm had misrepresented its costs at the time at which prices were set he can order a refund to consumers in the optimal policy the regulator audits when the firm reports for pricing purposes that its costs will be high and orders a refund when the auditfinds that realized costs are lower than anticipated given the original report a separation result that obtains for an important case indicates that the initial pricing decision is independent of the auditing decision the auditing decision however depends on the price that was initially set the optimal auditing strategy is characterized and the nature of the welfare gains are identified the methodology used in the analysis involves the characterization of an equilibrium of a revelation game with an ex post observable

on fiscal multipliers estimates from a medium scale dsge model this paper contributes to the debate on fiscal multipliers in the context of a structural model i estimate a micro founded dynamic stochastic general equilibrium model that features a rich fiscal policy block and a transmission mechanism for government spending shocks using bayesian techniques for us data

can government purchases stimulate the economy this essay briefly reviews the state of knowledge about the government spending multiplier drawing on theoretical work aggregate empirical estimates from the united states as well as cross locality estimates i assess the likely range of multiplier values for the experiment most relevant to the stimulus package debate a temporary deficit financed increase in government purchases i conclude that the multiplier for this type of spending is probably between 0 8 and 1 5 jel e23 e62 h50

housing dynamics over the business cycle housing dynamics over the business cycle over the u s business cycle fluctuations in residential investment are well known to systematically lead gdp these dynamics are documented here to be specific to the u s and canada in other developed economies residential investment is broadly coincident with gdp nonresidential investment has the opposite dynamics being coincident with or lagging gdp these observations are in sharp contrast with the properties of nearly all business cycle models with disaggregated investment including mortgages and interest rate dynamics aligns the theory more closely with u s observations longer time to build in housing construction makes residential investment coincident with output

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

tax expenditures for owner occupied housing deductions for property taxes and mortgage interest and the exclusion of imputed rental income federal income tax policy affects the cost of homeowner ship for many households popular discussions of the favorable tax treatment of owner occupied housing usually focus on the tax deductibility of mortgage interest and prop erty tax payments as well as the specialized tax rules that affect housing capital gains academic discussions in contrast emphasize the exclusion of the imputed rental income on owner occupied housing as the key tax benefit for homeowners this paper summarizes the current distribution of the tax benefits associated with the mortgage interest and property tax deductions it contrasts this with the distribution of tax benefits asso ciated with the current tax regime for imputed rental income relative to one that taxes home

are government spending multipliers greater during periods of slack evidence from 20th century historical data a key question that has arisen during recent debates is whether government spending multipliers are larger during periods of slack some researchers and policymakers have argued that while government spending multipliers are estimated to be modest on average they might become greater during times when resources are underutilized auerbach and gorodnichenko 2012 forthcoming henceforth ag test this hypothesis and find larger multipliers dur

austerity and private debt this study provides empirical evidence that the costs of austerity crucially depend on the level of private indebtedness in particular fiscal consolidations lead to severe contractions when implemented in high private debt states contrary fiscal consolidations have no significant effect on economic activity when private debt is low these results are robust to alternative definitions of private debt overhang the composition of fiscal consolidations and controlling for the state of the business cycle and government debt overhang i show that deterioration in household balance sheets is important to understand private debt dependent effects of austerity

fiscal policy in good times and bad in the 1980s several countries with large government debt or deficit implemented substantial and in some cases drastic deficit cuts contrary to widespread expectations in many cases private consumption boomed rather than contracted this paper shows that in times of fiscal stress shocks to government revenues and especially expenditure have very different effects on private consumption than in normal times

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

optimal regulation of multinationals under collusion this paper analyses the optimal collusion proof mechanism for the regulation of multinational firms mnfs in foreign direct investment fdi projects there is a host country with a profitable investment opportunity either a multinational firm mnf or a local firm lf can undertake this project nonetheless due to its firm specific advantage and the mnf has the potential to create a larger surplus the host government faces an informational constraint such that it cannot observe the extra surplus the mnf can generate using this set up karabay 2010 shows that employing foreign ownership restrictions to force a joint venture jv can help the host government to partially overcome its information disadvantage in this paper we extend karabay 2010 by studying the host government s optimal regulatory policy when the mnf and the lf can collude it turns out collusion imposes no cost on the host government and the expected welfare attained in the absence of collusion can still be secured under collusion

determinants of thrift institution resolution costs this paper provides a detailed examination of the cost imposed by thrift institutions resolved during the period 1980 1988 a simple model is presented to explain the cost of resolution this model is tested empirically with a comprehensive data set that permits us to avoid some of the econometric problems present in earlier studies the empirical evidence suggests that the model that explains resolution costs in the late 1980s is significantly different from the model for either the middle or early 1980s this evidence is consistent with the changing nature of the thrift crisis and changes in the regulator s closure rule our econometric evidence moreover is consistent with the hypothesis that for troubled institutions tangible net worth systematically understates market value net worth in addition the importance of including time effects as well as institution effects as determinants of the cost of resolution is revealed the sharp increase in market interest rates in late 1979 and early 1980 and the deregulation of deposit rates led to record losses in the thrift industry in the early 1980s and to a major erosion of the industry s capital many institutions never fully recovered from these problems and most currently insolvent thrift

instrument choice the demand for mortgages in canada abstract this paper is directed at understanding the factors which caused mortgage demand to fluctuate to the degree witnessed in the 1980s we model the mortgage choice decision as involving simultaneous options on both the term and the amortization choice by cost minimizing risk averse borrowers the model is estimated using a bivariate ordered probit methodology an extensive database containing details on the financial and demographic characteristics of households is used we find that contrary to the dominant model of mortgage demand borrowers react to market conditions in a risk averse and cost minimizing manner

regulation of multinational firms with two active governments a common agency approach abstract when a government agency imposes cost based taxes regulations on a multinational with private cost information it may initiate countervailing regulations by another of the governments with which the multinational interacts we analyze the problem of optimal regulation of a multinational under incomplete cost information via trade taxes by multiple governments as a problem of common agency with adverse selection by focusing on the game played by the competing governments we characterize the equilibrium trade taxes and show that the non cooperative behavior of the governments not only reduces aggregate national welfare but also reduces firm profits

interest rate pass through mortgage rates household consumption and voluntary deleveraging abstract exploiting variation in the timing of resets of adjustable rate mortgages arms we find that a sizable decline in mortgage payments up to 50 percent induces a significant increase in c

multinational firms global strategies host country indigenisation of ownership and welfare abstract this paper examines the costs and benefits that may arise when host countries aim to indigenise the ownership of foreign subsidiaries it is shown that there may be an optimal level of indigenisation beyond which the marginal social costs of such policies will exceed the corresponding benefits the analysis also shows that the optimum indigenisation may depend among other things on whether the subsidiary is autonomous or fully controlled by the parent company a further result is that if the subsidiaries equity is purchased by private firms or individuals the privately optimum level of indigenisation is likely to be greater than the socially optimum

leaning against the wind during financial disruptions market makers provide liquidity by absorbing external selling pressure they buy when the pressure is large accumulate inventories and sell when the pressure alleviates this paper studies optimal dynamic liquidity provision in a theoretical market setting with large and temporary selling pressure and order execution delays i show that competitive market makers offer the socially optimal amount of liquidity provided they have access to sufficient capital if raising capital is costly this suggests a policy role for lenient central bank lending during financial disruptions

output spillovers from fiscal policy in this paper we estimate the cross country spillover effects of government purchases on output for a large number of oecd countries following the methodology in auerbach and gorodnichenko 2012a b we allow these multipliers to vary smoothly according to the state of the economy and use real time forecast data to purge policy innovations of their predictable components we also consider the responses of other key macroeconomic variables our findings suggest that cross country spillovers have an important impact and also confirm those of our earlier papers that fiscal shocks have a larger impact when the affected country is in recession

the costs of macroprudential policy abstract central banks increasingly rely on macroprudential measures to manage the financial cycle however the effects of such measures on the core objectives of monetary policy to stabilise output and inflation are largely unknown in this paper we quantify the effects of changes in maximum loan to value ltv ratios on output and inflation we rely on a narrative identification approach based on detailed reading of policy makers objectives when implementing the measures we find that over a four year horizon a 10 percentage point decrease in the maximum ltv ratio leads to a 1 1 reduction in output as a rule of thumb the impact of a 10 percentage point ltv tightening can be viewed as roughly comparable to that of a 25 basis point increase in the policy rate however the effects are imprecisely estimated and the effect is only present in emerging market economies we also find that tightening ltv limits has larger economic effects than loosening them at the same time we show that changes in maximum ltv ratios have substantial effects on credit and house price growth using inverse propensity weights to rerandomise ltv actions we show that these effects are likely causal

credit booms and macrofinancial stability this paper explores several questions about credit booms and busts when do credit booms occur when do they end up in busts and when do they not what are the implications for different policies if curbing credit growth and or mitigating the associated risks is an objective we find that credit booms are often associated with financial reform and economic growth they also tend to be more frequent in fixed exchange rate regimes only one in three credit boom episodes are followed by a financial crisis these booms tend to be larger and last longer macroprudential tools have at times proven effective in containing booms and more often in limiting the consequences of busts due to the buffers they helped to build

estimating fiscal multipliers news from a non linear world we estimate non linear vars to assess to what extent fiscal spending multipliers are countercyclical in the us we deal with the issue of non fundamentalness due to fiscal foresight by appealing to sums of revisions of expectations of fiscal expenditures this measure of anticipated fiscal shocks is shown to carry valuable information about future dynamics of public spending results based on generalised impulse responses suggest that fiscal spending multipliers in recessions are greater than one but not statistically larger than those in expansions however non linearities arise when focusing on extreme events that is deep recessions versus strong expansionary periods

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

robustly collusion proof implementation a contract with multiple agents may be susceptible to collusion we show that agents collusion imposes no cost in a large class of circumstances with risk neutral agents including both uncorrelated and correlated types in those circumstances any payoff the principal can attain in the absence of collusion including the second best level can be attained in the presence of collusion in a way robust to many aspects of collusion behavior the collusion proof implementation generalizes to a setting in which only a subset of agents may collude provided that noncollusive agents incentives can be protected via an ex post incentive compatible and ex post individually rational mechanism our collusion proof implementation also sheds light on the extent to which hierarchical delegation of contracts can optimally respond to collusion
