Abstract This article introduces corporate governance frictions into a growth model with endogenous market structure. Managers engage in corporate resource diversion and empire building. Shareholders discipline managers with incentive compensation contracts. A reform that mitigates corporate governance frictions boosts firms’ entry and, for a given market structure, has an ambiguous impact on incumbents’ return to product improvement. However, as the market structure adjusts, becoming more diffuse, incumbents invest less in product improvement. Calibrating the model to U.S. data, we find that a reform of the kind recently enacted in several advanced economies can lead to a welfare loss.

We study the causes behind the shift in the level of U.S. GDP following the Great Recession. To this end, we propose a model featuring endogenous productivity à la Romer and a financial friction à la Kiyotaki–Moore. Adverse financial disturbances during the recession and the lack of strong tailwinds post‐crisis resulted in a severe contraction and the downward shift in the economy's trend. Had financial conditions remained stable during the crisis, the economy would have grown at its average growth rate. From a historical perspective, the Great Recession was unique because of the size and persistence of adverse shocks, and the lackluster performance of favorable shocks since 2010.

This article studies the full equilibrium dynamics of an economy with financial frictions. Due to highly nonlinear amplification effects, the economy is prone to instability and occasionally enters volatile crisis episodes. Endogenous risk, driven by asset illiquidity, persists in crisis even for very low levels of exogenous risk. This phenomenon, which we call the volatility paradox, resolves the Kocherlakota ( 2000) critique. Endogenous leverage determines the distance to crisis. Securitization and derivatives contracts that improve risk sharing may lead to higher leverage and more frequent crises. (JEL E13, E32, E44, E52, G01, G12, G20)

Credit market imperfections influence the labor market and aggregate economic activity. In turn, macroeconomic factors have an impact on the credit sector. To assess these effects in a tractable general-equilibrium framework, we introduce endogenous search frictions, in the spirit of Peter Diamond (1990), in both credit and labor markets. We demonstrate that credit frictions amplify macroeconomic volatility through a financial accelerator. The magnitude of this general-equilibrium accelerator is proportional to the credit gap, defined as the deviation of actual output from its perfect credit market level. We explore various extensions, notably endogenous wages.

Abstract We present a model of heterogeneous firms and misallocation in which financial frictions are partially overcome if more human resources are devoted to intermediation, at the cost of having fewer resources employed in directly productive activities. Not only does an inefficient financial sector result in an inefficient final good sector; an inefficient final good sector results in an inefficient financial sector. Exogenous inefficiencies in the productive sector generate decreased demand for financial services, which translates into a smaller and less efficient financial sector, worsening the resource allocation in the productive sector. This direction of causality seems in line with cross-country evidence.

This paper examines an economy in which output is produced by state-owned enterprises and private firms. Private-capital formation requires intermediation that is subject to a credit market friction. In this environment, I look at the effects of a privatization policy that transfers state-owned capital to the private sector. Multiple steady-state equilibria are possible. When these arise, the low-wage equilibrium features a relatively inefficient financial system and privatization transfers help to increase the aggregate capital stock by reducing the severity of the credit market frictions. On the other hand, privatization transfers may have adverse effects when the economy is at the high-wage equilibrium. Analysis of the dynamic characteristics of the model reveals that development trap phenomenon and endogenous fluctuations can be observed.

Since 1997, the Department of Economics of the University of Crete has organized an annual international conference on macroeconomic analysis and international finance. The articles included in this special issue are refereed versions of papers presented at the 17th International Conference on Macroeconomic Analysis and International Finance held at the University Campus, Rethymno, 30 May–1 June 2013, and submitted to Macroeconomic Dynamics in an open call for papers. The central theme of this Special Issue is Growth, Optimal Fiscal and Monetary Policy, and Financial Frictions. The topics discussed in this issue are endogenous growth and public investment and taxation; optimal inflation and fiscal and monetary policy; foreign reserve accumulation and China's exchange rate policy; and liquidity shocks and financial frictions. We begin the Special Issue with an overview of these papers.

I develop a macroeconomic model in which banks can affect loan quality by exerting costly screening effort. Informational frictions limit the amount of external funds that banks can raise. In this framework, I consider two types of financial intermediation: traditional banking and shadow banking. By pooling different loans, shadow banks achieve a higher endogenous leverage compared to traditional banks, increasing credit availability. However, shadow banks also make the financial sector more fragile because of the lower quality of the loans they finance and because of their exposure to bank runs. In this setting, unconventional monetary policy can reduce macroeconomic instability. (JEL E32, E44, E52, G01, G21, G23, L25)

Durant la grande récession, les interactions entre fluctuations du prix de l’immobilier, du travail et de l’entrée des firmes sur le marché des biens, ont mis en avant l’existence de relations étroites entre ces marchés. Le but de cette thèse est de mettre en lumière les interactions entre le marché du travail et le marché des biens ainsi que des cycles financiers, en utilisant les récents progrès des modèles DSGE. Dans le premier chapitre, nous avons trouvé un fort rôle joué par la création de firmes dans l’amplification des dynamiques de l’emploi. En introduisant le mécanisme du modèle de Diamond-Mortensen-Pissarides sur le marché du travail, nous avons pu étudier sous un nouvel angle les fluctuations du taux de marge des firmes. Comparé aux travaux théoriques utilisant un marché du travail sans frictions, nous avons trouvé un taux de marge moins contracyclique dû au coût marginal acyclique d’un modèle avec frictions. De plus, le rôle accordé à la création de firmes dans la détermination du taux de marge est moins important que dans les papiers précédents. Dans le second chapitre, nous avons lié la capacité d’endettement des ménages avec leur situation sur le marché de l’emploi. Grâce à cette microfondation, les nouveaux arrivants sur le marché du travail entrainent un plus haut niveau de dette immobilière tandis que ceux qui perdent leurs emplois sont exclus du marché du crédit. En conséquence, le ratio LTV devient endogène et répond de manière procyclique aux fluctuations de l’emploi. Nous avons montré que cette modélisation était empiriquement fondée et résout les anomalies d'une contrainte de crédit standard. Dans le dernier chapitre, nous avons étendu l’analyse précédemment effectuée en intégrant des firmes qui s’endettent dans le but d’obtenir un cycle financier plus complet. Le premier résultat est qu’une contrainte de crédit pour les firmes intégrant à la fois les biens immobiliers, le capital et la masse salariale permet de mieux rendre compte des fluctuations sur le marché du travail comparativement aux contraintes n’intégrant qu’une partie de ces trois composantes. Le second résultat met en évidence le rôle des fluctuations immobilières et du crédit sur l’emploi. Les deux derniers chapitres ont d’importantes implications pour les politiques économiques. Une réforme structurelle du marché du travail visant à le déréguler entraine une forte hausse de la dette immobilière pour les ménages ainsi que du prix de l’immobilier et une augmentation moindre de la dette des firmes. Notre approche révèle qu’une politique macroprudentielle visant à restreindre la capacité d’emprunt des ménages conduit à des effets positifs à long terme pour l’économie tout en limitant les effets sur le marché immobilier (dette et prix). A l’inverse, une politique macroprudentielle visant à réduire l’emprunt des entreprises conduit à l’effet inverse avec des effets négatifs à long terme pour l’économie
During the Great Recession, the interactions between housing, labor and entry highlight the existence of narrow propagation channels between these markets. The aim of this thesis is to shed a light on labor market interactions with firm entry and financial business cycles, by building on the recent theoretical and empirical of DSGE models. In the first chapter, we have found evidence of the key role of the net entry as an amplifying mechanism for employment dynamics. Introducing search and matching frictions, we have studied from a new perspective the cyclicality of the mark-up compared to previous researches that use Walrasian labor market. We found a less countercyclical markup due to the acyclical aspect of the marginal cost in the DMP framework and a reduced role according to firm's entry in the cyclicality of the markup. In the second chapter, we have linked the borrowing capacity of households to their employment situation on the labor market. With this new microfoundation of the collateral constraint, new matches on the labor market translate into more mortgages, while separation induces an exclusion from financial markets for jobseekers. As a result, the LTV becomes endogenous by responding procyclically to employment fluctuations. We have shown that this device is empirically relevant and solves the anomalies of the standard collateral constraint. In the last chapter, we extend the analysis developed in the previous one by integrating collateral constrained firms in order to have a more complete financial business cycle. The first result is that an entrepreneur collateral constraint integrating capital, real commercial estate and wage bill in advance is empirically relevant compared to the collateral literature associated to the labor market which does not consider these three assets. The second finding is the role of the housing price and credit squeezes in the rise of the unemployment rate during the Great Recession. The last two chapters have important implications for economic policy. A structural deregulation reform in the labor market induces a significant rise in the debt level for households and housing price, combined with a substantial rise of firm debt. Our approach allows us to reveal that a macroprudential policy aiming to tighten the LTV ratio for household borrowers has positive effects in the long run for output and employment, while tightening LTV ratios for entrepreneurs leads to the opposite effect

La contrazione della formazione di imprese dopo la crisi finanziaria del 2008 è stata in parte determinata dall'inasprimento degli standard creditizi. Incorporare l'imperfezione del mercato del credito nei modelli DSGE è diventato un passo essenziale verso una migliore spiegazione di tali risultati. Nel primo capitolo, indago sul ruolo del finanziamento esterno nella creazione d'impresa. Sottolineo l'impatto del potere di mercato delle banche e la presenza di dispersione tra i tassi di interesse dei grandi e dei piccoli prestiti all'ingresso. Pertanto, sviluppo un modello DSGE che collega l'ingresso dell'impresa al sistema bancario imperfetto e introduco costi di prestito eterogenei per operatori storici e nuovi. Il modello prevede un impatto amplificato degli shock reali e finanziari e mostra una maggiore volatilità man mano che lo spread dei tassi di interesse si allarga. In linea con l'evidenza, la versione sticky-price produce un'entrata prociclica in risposta allo shock monetario espansivo. Nel secondo capitolo, mi concentro sull'interazione tra i prezzi delle case, le insolvenze sui prestiti e l'ingresso di imprese. Presento prove SVAR che rivelano una risposta prociclica positiva della nascita allo shock dei prezzi delle case e una reazione negativa alle inadempienze sui prestiti. Quindi sviluppo un modello DSGE in grado di prevedere e spiegare queste risposte. L'endogeneità del vincolo collaterale e della creazione d'impresa è al centro del meccanismo del modello. Il modello genera dei secondi momenti ragionevolmente vicini alle controparti dei dati.
The contraction of business formation after 2008 financial crisis was driven partly by the tightened credit standards. Incorporating credit market imperfection to DSGE models became an essential step towards better explaining such outcomes. In the first chapter, I investigate the role of external financing in firm creation. I highlight the impact of bank market power, and the presence of dispersion between interest rates of large and small loans on entry. Therefore, I develop a DSGE model linking firm entry to imperfect banking system, and introduce heterogeneous borrowing costs for incumbents and entrants. The model predicts amplified impact of real and financial shocks, and exhibits higher volatility as the spread in interest rates gets wider. In line with evidence, the sticky-price version produces pro-cyclical entry in response to expansionary monetary shock. In the second chapter, I focus on the interaction between house prices, loan defaults, and firm entry. I present SVAR evidence that reveals positive pro-cyclical response of birth to house price shock, and negative reaction to loan defaults. Then I develop a DSGE model that is able to predict and explain these responses. The endogeneity of collateral constraint and firm creation is in the core of the model’s mechanism. The model generates some second moments that are reasonably close to their data counterparts.

This thesis studies the self-fulfilling business cycles in a dynamic stochastic general equilibrium model with financial market frictions. It consists of three papers. The first paper uncovers a series of belief shocks (a.k.a animal spirits) that drive the U.S. economy from both financial markets data and the structure of a financial accelerator model with borrowing constraint. It finds that the computed belief shocks are well identified and resemble the observable proxy in the real world. Furthermore, the model economy in which only sunspot shocks matter performs at least as well as a standard real business cycle model driven by technology shocks in replicating major U.S. business cycle facts and it outperforms the real business cycle model in some other dimensions. The second paper investigates the role of people's animal spirits in an estimated artificial economy with financial market frictions via Bayesian methods. It demonstrates that people's animal spirits are prime drivers of U.S. business cycle fluctuations. Animal spirits shocks account for well over a third of output fluctuations over the period from 1955 to 2014. Financial friction and technology shocks are considerably less important. It also finds that a substantial part of aggregate output's contraction during the Great Recession was caused by adverse shocks to expectations. The third paper follows the path of Adelman and Adelman (1959), applying the classical business cycle method proposed by Burns and Mitchell (1946) to evaluate the cyclical properties of an animal spirits model that is estimated in the second paper. In particular, the paper examines whether the model can reproduce qualitative features of U.S. business cycle. The results indicate an adequately high degree of coincidence in main macroeconomic aggregates between the business cycle features identified in actual time series data and those found in model economy.

Questions have been raised regarding the role of low tax offshore jurisdictions in the global financial crisis, based largely on evidence that many problematic asset-backed securities were issued from or listed in the Cayman Islands, Jersey, Ireland, and other offshore sites. However, there has not been a systematic investigation of the offshore geography of crisis-implicated securitization. This chapter fills this gap by constructing the first comprehensive jurisdictional map of the largest pre-crisis asset-backed commercial paper (ABCP) programs, and examining the rationale for and impacts of this geography in detail. It shows that offshore jurisdictions were disproportionately involved in producing the most unstable ABCP classes. However, this is difficult to explain in terms of the traditional role of offshore banking centers as sites for direct avoidance of onshore regulation and transparency. Rather, the chapter proposes a Minskian model of pre-crisis offshore ABCP production, wherein these jurisdictions specialized in alleviating incidental institutional frictions (e.g. double taxation) hindering onshore financial innovation. In this context, they could sometimes be legitimately described as improving the institutional “efficiency” of financial markets. However, by facilitating the endogenous evolutionary instability of these markets, this apparently innocuous service had profoundly negative effects. This normative disconnect poses a conundrum for offshore reform, and indeed highlights the intrinsic limitations of financial regulation more broadly.

This paper discusses the role of sterilized foreign exchange (FX) interventions as a monetary policy instrument for emerging market economies in response to external shocks. We develop a model for a commodity-exporting small open economy in which FX intervention is considered as a balance sheet policy induced by a financial friction in the form of an agency problem between banks and their creditors. The severity of banks agency problem depends directly on a bank-level measure of currency mismatch. Endogenous deviations from the standard UIP condition arise at equilibrium. In this context, FX interventions moderate the response of financial and macroeconomic variables to external shocks by leaning against the wind with respect to real exchange rate pressures. Our quantitative results indicate that, conditional on external shocks, the FX intervention policy successfully reduces credit, investment, and output volatility, along with substantial welfare gains when compared to a free-floating exchange rate regime. Finally, we explore distinct generalizations of the model that eliminate the presence of endogenous UIP deviations. In those cases, FX intervention operations are considerably less effective for the aggregate equilibrium.
