Thesis advisor: Donald Cox / What fraction of college-age youths in the United States comes from credit-constrained families? Can subjective assessments of financial difficulties inform the debate about pervasiveness of credit constraints in the demand for college education? My dissertation contains two essays addressing these questions. Credit constraints in education may lead to inefficient skill allocations and perpetuate imbalances in the distribution of economic well-being. Unfortunately, empirical evidence regarding their pervasiveness in the United States has not been consistent, in part because constraints tend to be inferred indirectly. The first essay evaluates how a potentially more direct measure can be used to enhance our understanding of the issue. I focus on subjective assessments of financial limitations available in the National Longitudinal Survey of Youth 1979 and find that about 12 percent of college-age individuals expect to underinvest in education because of financial reasons or the need to work. While the measure developed in this paper is noisy and not a precise indicator of credit constraints, it appears to capture important variations in educational choices, beyond these captured by the standard controls, such as parental income. The contribution of the second essay is the use of parents' reports of borrowing limitations in the NLSY79 Young Adult Supplement to evaluate the proportion of constrained college-age youths in the early 2000s. The focus on the 2000s is critical because the sharp increase in tuition costs and gradual erosion of real student borrowing limits over the past two decades have potentially made credit constraints in education more widespread. My analysis sample is limited to children of young mothers who are more likely to be disadvantaged economically and hence are of specific interest to policy-makers. Over one-fifth of youths in the sample come from families where mothers report borrowing limitations. Conditional on scholastic ability, family income, and family background characteristics, parental constraints have a strong negative correlation with children's college attendance. Although my results do not distinguish between alternative explanations for borrowing limitations, they do suggest that researchers interested in the connection between liquidity constraints and education might benefit from paying more attention to direct measures. / Thesis (PhD) — Boston College, 2009. / Submitted to: Boston College.

Thesis advisor: Ryan A. Chahrour / The dissertation studies the primary sources of business-cycle fluctuations and their interaction with uncertainty and financial frictions. In my work, I examine the degree to which changes in uncertainty and financial conditions can be independent drivers of economic fluctuations; I study the sources of boom-bust cycles and whether they are linkedto credit market sentiments; and I ask how financial frictions affect economic fluctuations in terms of prices and quantities. In "Financial and Uncertainty Shocks", I separately identify financial and uncertainty shocks using a novel SVAR procedure and discuss their distinct monetary policy implications. The procedure relies on the qualitatively different responses of corporate cash holdings: after a financial shock, firms draw down their cash reserves as they lose access to external finance, while uncertainty shocks drive up cash holdings for precautionary reasons. Although both financial and uncertainty shocks are contractionary, my results show that the former are inflationary while the latter generate deflation. I rationalize this pattern in a New-Keynesian model: after a financial shock, firms increase prices to raise current liquidity; after an uncertainty shock, firms cut prices in response to falling demand. These distinct channels have stark monetary policy implications: conditional on uncertainty shocks the divine coincidence applies, while in case of financial shocks the central bank can stabilize inflation only at the cost of more unstable output fluctuations. In "What are the Sources of Boom-Bust Cycles?", joint with Vito Cormun, we provide a synthesis of two major views on economic fluctuations. One view maintains that expansions and recessions arise from the interchange of positive and negative persistent exogenous shocks to fundamentals. This is the conventional view that gave rise to the profusion of shocks used in modern dynamic stochastic general equilibrium models. In contrast, a second view, which we call the endogenous cycles view, holds that business cycle fluctuations are due to forces that are internal to the economy and that endogenously favor recurrent periods of boom followed by a bust. In this environment, cycles can occur after small perturbations of the long run equilibrium. We find empirical evidence pointing at the coexistence of both views. In particular, we find that the cyclical behaviour of economic aggregates is due in part to strong internal mechanisms that generate boom-bust phenomena in response to small changes in expectations, and in part to the interchange of positive and negative persistent fundamental shocks. Motivated by our findings, we build a theory that unifies the dominant paradigm with the endogenous cycles approach. Our theory suggests that recessions and expansions are intimately related phenomena, and that understanding the nature of an expansion, whether it is driven by fundamentals or by beliefs, is a first order issue for policy makers whose mandate is to limit the occurrance of inefficient economic fluctuations. In "COVID-19 and Credit Constraints'', joint with Pierluigi Balduzzi, Emanuele Brancati, and Fabio Schiantarelli, we investigate the economic effects of the COVID-19 pandemic and the role played by credit constraints in the transmission mechanism, using a novel survey of expectations and plans of Italian firms, taken just before and after the outbreak. Most firms revise downward their expectations for sales, orders, employment, and investment, while prices are expected to increase at a faster rate, with geographical and sectoral heterogeneity in the size of the effects. Credit constraints amplify the effects on factor demand and sales of the COVID-19 generated shocks. Credit-constrained firms also expect to charge higher prices, relative to unconstrained firms. The search for and availability of liquidity is a key determinant of firms' plans. Finally, both supply and demand shocks play a role in shaping firms' expectations and plans, with supply shocks being slightly more important in the aggregate. / Thesis (PhD) — Boston College, 2021. / Submitted to: Boston College.

O intento do trabalho é verificar se empresas com ações negociadas na Bovespa enfrentam restrição ao crédito. A análise de painel com base em dados de balanço patrimonial para o período de 2001 a 2005 revelou que, diferentemente do que se esperava, empresas de grande porte apresentam maior dependência dos fluxos de caixa para efetivar seus investimentos. Todavia, há argumentos teóricos na literatura que fundamentam esses resultados, bem como outras evidências empíricas semelhantes. / The paper focuses on evaluating whether Brazilian listed firms have faced financial constraints. Relying on data over the period 2001-2005, a panel data analysis was carried out, but the evidence raised turned out differently from the initially expected: large firms are more sensitive to cash flows to undertake their investment than smaller ones. Nonetheless, the recent literature provides theoretical rationale to deal with those findings as well as empirical evidence consistent with them.

This paper explores the 2008-2009 Global Trade Collapse to estimate the effects of a credit supply shock on exporters\' investments decisions. Using a Brazilian firm-level dataset compiled by the Brazilian Internal Revenue Service (IRS) over the period 2007-2013, I pair up export-intensive firms with their domestically-oriented counterparts to, subsequently, calculate the differences in terms of sensitivity of investment to cash flow between the two groups over the years. After controlling for the effect of international falling demand, my study reveals that exporters are more severely constrained than their peers in the control group only in 2009, when the supply of credit instruments to finance international trade shrank. Given their high need of external financing to support exporting activities and the volatility of the cost of trade finance, usually priced against 3-month Libor, my results are in line with expected. A number of robustness and placebo tests confirm the validity of the findings. / Este artigo explora o colapso do comércio global em 2008-2009 no intuito de estimar os efeitos de um choque de oferta de crédito nas decisões de investimento das empresas exportadoras. Utilizando dados em painel de empresas brasileiras no período 2007-2013, compilados pela pela Receita Federal do Brasil (RFB), é feito pareamento entre empresas exportadoras e as focadas no mercado interno e, em seguida, calculadas as diferenças na sensibilidade do investimento ao fluxo de caixa entre os dois grupos ao longo dos anos. Depois de controlar o efeito da queda da demanda internacional, meu estudo revela que as exportadoras ficaram mais restritas a crédito que suas similares do grupo de controle somente no ano de 2009, quando a oferta de instrumentos de crédito para o setor encolheu. Dada a alta necessidade de financiamento externo para apoiar as atividades de exportação e a volatilidade do custo dos instrumentos de crédito destinados a estas, geralmente precificados em relação à Libor de 3 meses, os resultados obtidos estão em linha com o esperado. Uma série de testes de robustez e placebo são realizados para confirmar a validade das inferências.

Historically, credit market conditions have been shown to impact economic activity, at times severely. For instance, in the late 2000s, the United States experienced a financial crisis that seized domestic and foreign credit markets. The ensuing lack of access to credit brought about a steep decline in output and a sluggish recovery. Accordingly, policymakers commonly take steps to mitigate the effects of adverse credit market conditions and, at times, conduct unconventional monetary policy once traditional policy tools become ineffective. This dissertation is a collection of essays regarding monetary policy, the flow of credit, financial crises, and the macroeconomy. Specifically, I describe monetary policy’s impact on the allocation of credit in the U.S. and analyze the role of upstream and downstream credit conditions and financial crises on international trade in a global supply chain. The first chapter assesses the impact of monetary policy shocks on credit reallocation and evaluates the importance of theoretical transmission mechanisms. Compustat data covering 1974 through 2017 is used to compute quarterly measures of credit flows. I find that expansionary monetary policy is associated with positive long-term credit creation and credit reallocation. These impacts are larger for long-term credit and for credit of financially constrained firms and firms that are perceived as risky to the lender. This is predicted by the balance sheet channel of monetary policy and mechanisms that reduce lenders’ risk perceptions and increase the tendency to search for yield. Furthermore, I find that, on average, the largest increases in credit creation resulting from monetary expansion are to firms that exhibit relatively low investment efficiency. These estimation results suggest that expansionary monetary policy may have a negative impact on future economic growth. The second chapter evaluates the quantitative effects of unconventional monetary policy in the late 2000s and early 2010s. This was a period when the traditional monetary policy tool (the federal funds rate) was constrained by the zero lower bound. We compute credit flow measures using Compustat data, and we employ a factor augmented vector autoregression to analyze unconventional monetary policy’s impact on the allocation of credit during the zero lower bound period. By employing policy counterfactuals, we find that unconventional monetary policy has a positive and simultaneous impact on credit creation and credit destruction and these impacts are larger in long-term credit markets. Applying this technique to analyze the flows of financially constrained and non-financially constrained borrowing firms, we find that unconventional monetary policy operates through the easing of collateral constraints because these effects are larger for small firms or those with high default probabilities. During the zero lower bound period, we also find that unconventional monetary policy brings about increases in credit creation for firms of relatively high investment efficiency. The third chapter pertains to the global trade collapse of the late 2000s. This collapse was due, in part, to strained credit markets and the vulnerability of exporters to adverse credit market conditions. The chapter evaluates the impact of upstream and downstream credit conditions and the differential effects of financial crises on bilateral trade. I find that upstream and downstream sectors’ needs for external financing is negatively associated with trade flows when the exporting or importing country’s cost of credit is high. However, I find that this effect is dampened for downstream sectors. I also find that downstream sectors’ value of collateral is positively associated with trade when the cost of credit is high in the importing country. High downstream trade credit dependence coupled with high costs of credit in the importing country also cause declines in imports. There are amplifying effects of credit costs for sectors that are highly dependent on external financing when the importing or exporting country is in financial crisis. Further, the magnitude is larger when the exporting country is in financial crisis. Finally, I find that these effects on trade flows are large when the exporting country is a developed economy, but they are muted for developing economies.

Microfinance is the number one buzz word in the development sphere nowadays. The basic idea of microfinance is to make financial services available for those excluded from the conventional banking system. By charging market price interest rates on the loans granted the business is meant to become sustainable and independent of fluctuations in cash flow from donor funding. The microfinance sector in Malawi is relatively young and still in the development phase. Since the majority of the charity organizations running microfinance projects in Malawi are originating from the Western world, the services these institutions offer are inherently affected by Western (Christian) banking culture. This paper investigates if this set up results in the exclusion of Malawi’s Muslim population due to the fact that Islamic law prohibits Muslims from charging or paying interest on loans. The conclusions of this thesis are that the Muslim population uses the microfinance services to the same extent as their Christian brethren. However, a large proportion of the Muslim clientele feel that they are morally prohibited from using the microfinance services because of the interest rate charged. They only make use of the interest-based loans because they have no other option, and would thereby prefer services compatible with Islamic law. My recommendation is for the microfinance institutions to embrace this knowledge and further investigate the need of Islamic microfinance, and the possibility to implement it, before the consequences becomes more than a moral issue.

We develop an entrepreneurship model in which heterogeneous producers face collateral constraints on production, but can hedge idiosyncratic shocks. Hedging works as a tool for reallocating resources to states in which they are more productively deployed, and can alleviate the effect of the financial frictions and be a counteracting force to capital misallocation. Government incentives to hedging improve workers’ welfare in steady state through an increase in TFP and wages. The intervention leads to a reduction in the rate of return of entrepreneurs and an increase in wealth dispersion. These two effects cause entrepreneurial welfare to decrease.

The purpose of this empirical research is to evaluate the relationship between credit constraints and household risky assets in China. The life-cycle hypothesis theory and household portfolio choice theory is the basis of the research. Using a probit model, we find out that credit constraints do not have a clear impact on the probability of households to hold risky assets. Furthermore, the coefficients between age and risky assets are non-linear. Households in urban regions have a high positive coefficient with risky assets. As for now, the literature is missing theories on the relationship between credit constraints and household financial risky assets in China. Thus, this study will enrich the literature of household financial assets allocation by using a questionnaire survey from CHFS (China Household Finance Survey).
