This thesis contains three essays. In the first essay, I provide new evidence on the failure of the Q theory of investment. The Q theory implies the state-by-state equivalence of stock returns and investment returns. However in the data, I find that investment and stock returns are negatively correlated. I also show that a production economy with time-to-build can explain these empirical facts. When I compute Q theory based investment returns on simulated data of the time-to-build model, they are uncorrelated with simulated stock returns, as in the data. Moreover, the model replicates the empirical negative correlation between stock returns and investment growth which some researchers have interpreted as evidence for irrational markets. In the second essay, I analyze the equilibrium effects of investment commitment on asset prices when the representative consumer has Epstein-Zin utility. Investment commitment captures the idea that long-term investment projects require not only current expenditures but also commitment to future expenditures. The general equilibrium effects of investment commitment and Epstein-Zin preferences generate endogenously time-varying first and second moments of consumption growth and stock returns. As a result, the first and second moments of excess returns are endogenously counter-cyclical, excess returns are predictable, and the equity premium increases by an order of magnitude. This paper also offers novel empirical findings regarding the predictability of returns. In the real and simulated data, the lagged investment rate helps to forecast the mean and volatility of returns. In the third essay, we embed a structural model of credit risk inside a consumption based model, which allows us to price equity and corporate debt in a single framework. Our key economic assumptions are that the first and second moments of earnings and consumption growth depend on the state of the economy which switches randomly, creating intertemporal risk, which agents prefer to resolve quickly because they have Epstein- Zin-Weil preferences. Our model generates co-movement between aggregate stock return volatility and credit spreads, consistent with the data, and potentially resolves the equity risk premium and credit spread puzzles.

In a production-based general equilibrium model, I study the impact of time-to-build and time-to-produce technology constraints and inventory on asset prices and macroeconomic quantity dynamics. A time-to-build constraint captures the delay in transforming new investment into productive capital; a time-to-produce constraint captures the delay in transforming productive capital into final products. Empirically, I find that the U.S. economy in aggregate exhibits approximately a three-quarter time-to-build and a four-quarter time-to-produce constraint. These delays in the production process introduce short-run risks in the economy where inventory accumulation facilitates consumption smoothing over time. Using this structure for time-to-build and time-to-produce constraints, I numerically calibrate a production-based general equilibrium model where the representative investor has recursive preferences over consumption and inventory. The model delivers first and second moments of macroeconomic quantities and asset prices consistent with the data. A small elasticity of intertemporal substitution is necessary to positively price the short-run risks induced by the production constraints. Inventories help fit the volatilities of asset returns, while the time-to-produce feature ensures nontrivial inventory holdings. In addition, the model is able to match empirical lead-lag patterns between asset prices and macroeconomic quantities as well as observed equity return predictability.

This thesis explores the effects of three important factors on a firm's investment and financing decisions, using contingent claim structural model. The first essay investigates how implementation lag impacts investment timing for a levered firm. The main finding is that implementation lag can potentially have a substantial effect on a company’s investment trigger. A crucial determinant of the lag-investment relationship is the fraction of investment cost that has to be incurred upfront. If this fraction is small, investment trigger is a decreasing function of implementation lag and the effect can be economically significant. If this fraction is large, investment trigger can be either increasing or decreasing in lag, but the magnitude of the effect is not large. The second essay investigates how future uncertain growth opportunity impacts a firm's investment timing decision and optimal leverage ratio. The firm has an option to expand profits after the first investment. However, the exercise of the growth option depends not only on the underlying profit flow but also on the uncertain arrival of the growth opportunity. The model illustrates that such uncertainty can significantly impact the initial investment timing for unlevered firm in a non-monotonic way. For levered firm, the future growth uncertainty, along with debt overhang problem, can shape the firm’s financing decision at initial investment. The third essay shows how risk-compensating performance-sensitive debt can be used to mitigate the “overinvestment” agency problem. We show that properly designed performance-sensitive debt can add significant value relative to fixed-coupon debt, and identify the risk-compensation level that maximizes shareholder wealth. The optimal risk-compensation level is found to be smaller than that required to eliminate overinvestment; thus, it is optimal for shareholders to incur some agency cost of overinvestment. / Thesis / Doctor of Philosophy (PhD)

[pt] Este artigo propõe um modelo de crescimento neoclássico usual, modificado para incluir um processo time-to-build na formação de capital público, taxa variável de utilização do capital, custos de ajustamento sobre o investimento privado e oferta de trabalho indivisível. Obedecendo a uma calibração restritiva para a economia dos Estados Unidos, as predições do modelo são comparadas à recente evidência empírica referente aos impactos dinâmicos de choques sobre o investimento público. Os resultados mostram que a utilização variável da capacidade instalada, juntamente com custos de ajustamento, explicam quantitativamente as respostas empíricas do PIB e do emprego. Este primeiro pressuposto do modelo também fornece uma intuição econômica para os resultados reportados pela literatura recente: eles são consistentes com efeitos de substituição intertemporal sobre as decisões de investimento. Em seguida à análise, um modelo de crescimento neoclássico usual, estendido para incluir um processo time-to-build para o capital público e taxação distorcionária, é usado para avaliar os efeitos de curto e longo prazo do Programa de Aceleração do Crescimento (PAC) no Brasil entre 2007 e 2010. Os resultados sugerem que o programa de investimento pode, na verdade, ter induzido desacelerações de curto prazo na economia brasileira, devido a defasagens de implementação do investimento público combinadas à tributação distorcionária. Ademais, as trajetórias de longo prazo derivadas no modelo dependem do esquema de financiamento distorcionário bem como de ajuste fiscal adotado. Finalmente, os efeitos de bem-estar associados ao programa são pequenos e diminuem conforme as defasagens de implementação dos gastos do governo aumentam. / [en] This paper proposes an otherwise standard neoclassical growth model extended for time-to-build process for public capital, varying capital utilization rate, adjustment costs in private investment and indivisible labor supply. Following a restrictive calibration for the U. S. economy, theoretical predictions are compared to the recent empirical evidence concerning the dynamic impacts of shocks to public investment. Results show that variable capacity utilization, together with adjustment costs, quantitatively accounts for GDP and employment empirical responses. This first assumption in the model also provides an economic intuition for the findings reported by the recent literature: they are consistent with plausible intertemporal substitution effects on investment decisions. Following this analysis, a standard neoclassical growth model extended for a time-to-build process for public capital and distortionary taxation is used to assess the short and long run effects of the Programa de Aceleração do Crescimento (PAC) in Brazil between 2007 and 2010. Findings suggest that the investment program may have actually induced short run slowdowns in the Brazilian economy due to implementation delays in public investment combined with distortive taxation. In addition, long run paths derived in the model depend on the adopted distortive financing as well as fiscal adjustment scheme. Finally, welfare effects associated to the program are small and decrease as the lags in implementation of government spending increases.

With the internationalization of financial markets, short-term capital flows to emerging market economies have become an important phenomenon in the world. The papers in this dissertation are concerned with investigating the effects of such flows in the receiving countries. The analysis is cast in a dynamic general equilibrium framework for small open economies. Two of the papers are quantitative investigations of the forces at work in small and relatively poor economies that liberalize trade and capital flows. The common approach of these papers is that of a computational experiment: calibrated simulations constitute a test of whether the models can explain certain dynamics which we observe in the data. The first paper investigates whether a calibrated two-sector neoclassical growth model can explain the magnitudes and the timing of capital flows in the Baltic countries after the fall of the Soviet Union. The results indicate that it can, and that the large and persistent trade deficits which we observe in the data need not be a reason to worry. However, the model also tells us that a reversal of capital flows and large sectoral adjustments lie ahead of the Baltic countries. In the second paper, the focus is on modelling the observed co-movement between consumption and the real exchange rate in Spain, which experienced large capital inflows following the entry into the European Community in 1986. In accordance with episodes of trade liberalization elsewhere, consumption in Spain boomed and the real exchange rate appreciated for several years after 1986. Standard two-sector models with traded and non-traded goods have problems accounting for these facts. The paper explores some mechanisms that can improve the standard modelling framework, and evaluates their quantitative importance in calibrated simulations for Spain. The third paper studies the government’s optimal bailout policy in an environment where sudden stops of capital flows cause financial crises in a small open economy. Real world events, such as the financial crises in the South East Asian countries in 1997, motivate the analysis. Compared to the previous essays, the paper is different in its nature in that it develops a highly stylized environment to analytically study the government’s optimal bailout policy. The paper shows that the government should optimally commit to a policy that only partially protects private debtors against inefficient liquidation. / Diss. Stockholm : Handelshögsk., 2004

Cette thèse vise à étudier les liens entre les investissements publics, le mode definancement et la croissance économique, tout en mettant en exergue le rôle des conditionsstructurelles. Premièrement, dans un scenario d’amélioration des conditions structurelles(mesurées par l’efficience et la capacité d'absorption de l’économie) comparé à un scenario debase, nous montrons que le potentiel de croissance est supérieur comparé au scenario de base. Parconséquent, la stabilisation de la dette ne nécessite pas des ajustements budgétaires douloureux.Deuxièmement, à travers un scénario d'investissement agressif sur la base d’emprunts nonconcessionnelsen anticipation des revenus futurs du pétrole, nous constatons l’occurrence decontraintes liées à la capacité d'absorption et partant l’effet adverse du syndrome hollandais sur lacroissance du PIB hors pétrole. En outre, des réformes structurelles qui résorberaient lescontraintes liées à l’inefficience et à la capacité d'absorption se traduiraient par une augmentationimportante et durable du capital public. Cela entrainerait une croissance supplémentaire du PIBhors pétrole. Troisièmement, nous montrons que les délais d’exécution peuvent contrer l’effetclassique selon lequel une augmentation de l’investissement public entraine un effet richessenégatif dans le long terme. Aussi, une productivité élevée de l’investissement public peutsubstantiellement créer un effet richesse positif dans le long terme, stimuler la production etpermettre à la consommation et à l’investissement privé de baisser moins. Finalement, noussimulons l’impact des dépenses publiques d’éducation sur la pauvreté au Burkina Faso en utilisant2 mécanismes d’ajustement fiscal : la taxe directe et la taxe indirecte. Les simulations montrentqu’une augmentation uniforme de 40 pourcent des dépenses publiques dans l’éducation primairefiancée par les deux mécanismes de financement améliore non seulement le bien-être maiségalement entraine une baisse de la pauvreté chez tous les types de ménage. Toutefois, lefinancement par la taxe indirecte conduit à un résultat inférieur comparé au financement par lataxe directe. / This dissertation seeks to study the public investment-financing-growth linkages whileeliciting the role of structural economic conditions. First, through an alternative scenario ofimproved structural economic conditions (efficiency and absorptive capacity) and comparing witha baseline scenario, we find that the growth potential is higher than the baseline. Consequently,stabilizing debt does not require painful fiscal consolidation. Second, through an aggressiveinvestment scaling-up scenario that builds on commercial borrowing in anticipation of future oilrevenue, we find that the economy is subject to absorptive capacity constraints and ultimately toDutch disease effects that affect negatively the non-oil GDP growth in the short run. Moreover,we find that structural reforms that address absorptive capacity constraints and inefficienciestranslate into sizable and sustainable increase in public capital. This in turn has a positive spillovereffect in terms of additional growth in the non-resource GDP. Third, we find that implementationdelays can offset the standard negative wealth effect from an increase in government investmentspending in the long run. Also, high-yielding public investment can substantially create positivewealth effect in the long run, raise output and enable private consumption and investment to fallless. Finally, we simulate a 40-percent across-the-board increase in public spending for primaryeducation, financed by an increase in taxes on household income and indirect taxes. We find thatthe two financing mechanisms, not only leads to an increase in the welfare but also to a decline inthe incidence of poverty for all household types. However, the indirect tax-based financing leadsto smaller outcomes compared to the income tax-based financing.
