Economic Development of Urban Areas

In this dissertation I study the development of urban areas. At the aggregate level I investigate how they may be affected by climate change policies and by being designated the seat of governmental power. At the household level I study with coauthors how microfinance could improve the health of urban residents. In Chapter 1, I investigate how local employment may be affected by electricity price increases, which is a likely consequence of climate change policies. I outline how previous studies that find large, negative effects may be biased. To overcome these biases I develop a novel estimation strategy that blends border-pair regressions with the synthetic control methodology. I show the conditions for consistent estimation. Using this estimator, I find no effect of contemporaneous price changes on employment. Consistent with the longer time-frame for manufacturing decisions, I do find evidence for negative effects from perceived permanent price shocks. These estimates are much smaller than previous research has found. National capital cities are often substantially larger than other cities in their countries. In Chapter 2, I investigate whether there is a causal effect from being a capital by studying the 1960 relocation of the Brazilian capital from Rio de Janeiro to Brasília. Using a synthetic controls strategy I find that losing the capital had no significant effects on Rio de Janeiro in terms of population, employment, or gross domestic product (GDP). I find that Brasília experienced large and significant increases in population, employment, and GDP. I find evidence of large spillovers from the public to the private sector. Chapter 3 investigates how microfinance could increase the uptake of costly health goods. We study the effect of time payments (micro-loans or micro-savings) on willingness-to-pay (WTP) for a water filter among households in the slums of Dhaka, Bangladesh. We find that time payments significantly increase WTP: compared to a lump-sum up-front purchase, median WTP increases 83% with a six-month loan and 115% with a 12-month loan. We find that households are quite patient with respect to consumption of health inputs. We find evidence for the presence of credit and savings constraints.

Essays in asset price bubbles

This thesis studies the field of asset price bubbles. It is comprised of three independent chapters. Each of these chapters either directly or indirectly analyse the existence or implications of asset price bubbles. The type of bubbles assumed in each of these chapters is consistent with rational expectations. Thus, the kind of price bubbles investigated here are known as rational bubbles in the literature. The following describes the three chapters. Chapter 1: This chapter attempts to explain the recent US housing price bubble by developing a heterogeneous agent endowment economy asset pricing model with risky housing, endogenous collateral and defaults. Investment in housing is subject to an idiosyncratic risk and some mortgages are defaulted in equilibrium. We analytically derive the leverage or the endogenous loan to value ratio. This variable comes from a limited participation constraint in a one period mortgage contract with monitoring costs. Our results show that low values of housing investment risk produces a credit easing effect encouraging excess leverage and generates credit driven rational price bubbles in the housing good. Conversely, high values of housing investment risk produces a credit crunch characterized by tight borrowing constraints, low leverage and low house prices. Furthermore, the leverage ratio was found to be procyclical and the rate of defaults countercyclical consistent with empirical evidence. Chapter 2: It is widely believed that financial assets have considerable persistence and are susceptible to bubbles. However, identification of this persistence and potential bubbles is not straightforward. This chapter tests for price bubbles in the United States housing market accounting for long memory and structural breaks. The intuition is that the presence of long memory negates price bubbles while the presence of breaks could artificially induce bubble behaviour. Hence, we use procedures namely semi-parametric Whittle and parametric ARFIMA procedures that are consistent for a variety of residual biases to estimate the value of the long memory parameter, d, of the log rent-price ratio. We find that the semi-parametric estimation procedures robust to non-normality and heteroskedasticity errors found far more bubble regions than parametric ones. A structural break was identified in the mean and trend of all the series which when accounted for removed bubble behaviour in a number of regions. Importantly, the United States housing market showed evidence for rational bubbles at both the aggregate and regional levels. In the third and final chapter, we attempt to answer the following question: To what extend should individuals participate in the stock market and hold risky assets over their lifecycle? We answer this question by employing a lifecycle consumption-portfolio choice model with housing, labour income and time varying predictable returns where the agents are constrained in the level of their borrowing. We first analytically characterize and then numerically solve for the optimal asset allocation on the risky asset comparing the return predictability case with that of IID returns. We successfully resolve the puzzles and find equity holding and participation rates close to the data. We also find that return predictability substantially alter both the level of risky portfolio allocation and the rate of stock market participation. High factor (dividend-price ratio) realization and high persistence of factor process indicative of stock market bubbles raise the amount of wealth invested in risky assets and the level of stock market participation, respectively. Conversely, rare disasters were found to bring down these rates, the change being severe for investors in the later years of the life-cycle. Furthermore, investors following time varying returns (return predictability) hedged background risks significantly better than the IID ones.

Uma análise da política econômica a partir do desempenho da indústria automotiva brasileira no cenário econômico de 2003-2014

Entre 2003 e 2008, o Brasil apresentou um positivo desempenho econômico em meio a um cenário externo favorável, entretanto a partir da crise de 2008, o governo brasileiro passou a adotar medidas anticíclicas a fim de minimizar os efeitos externos da crise. Essas medidas objetivaram o incentivo da demanda agregada, o que realmente sofreu um efeito positivo de curto prazo, entretanto essas políticas, além de apresentar uma natureza limitada, podem levar a cenários futuros indesejados para o desenvolvimento econômico, como o aumento da inadimplência e taxa elevadas de inflação. Somado a isso, as medidas de incentivos de inovação e de desenvolvimento tecnológico foram interrompidas pela crise ou não implementadas de forma efetiva. Diante disto, a monografia se propõe a analisar os efeitos dessas políticas de incentivo à demanda adotada no período a partir de uma análise da indústria automotiva brasileira, uma das indústrias mais poderosas e receptoras de incentivos governamentais, já que apresenta um caráter dinâmico e movimenta um grande número de indústrias de base. Logo, para que a indústria automotiva cresça e se desenvolva de forma sustentável, bem como os outros setores, o incentivo não deve ser de cunho setorial, por tanto, temporário, deve ser de natureza permanente e abrangente. Além disso, um incentivo da demanda terá resultados positivos com os incentivos tecnológicos, inovadores e de qualificação do capital humano para uma crescente exportação, levando a saldos positivos da balança comercial e, consequentemente, maiores investimentos a partir de uma indústria mais competitiva.

Tangibilidade, classe de ativos e estrutura de capital das empresas listadas na BM&FBOVESPA

This study aims to investigate the influence of the asset class and the breakdown of tangibility as determinant factors of the capital structure of companies listed on the BM & FBOVESPA in the period of 2008-2012. Two current assets classes were composed and once they were grouped by liquidity, they were also analyzed by the financial institutions for credit granting: current resources (Cash, Bank and Financial Applications) and operations with duplicates (Stocks and Receivables). The breakdown of the tangible assets was made based on its main components provided as warrantees for loans like Machinery & Equipment and Land & Buildings. For an analysis extension, three metrics for leverage (accounting, financial and market) were applied and the sample was divided into economic sectors, adopted by BM&FBOVESPA. The data model in dynamic panel estimated by a systemic GMM of two levels was used in this study due its strength to problems of endogenous relationship as well as the omitted variables bias. The found results suggest that current resources are determinants of the capital structure possibly because they re characterized as proxies for financial solvency, being its relationship with debt positive. The sectorial analysis confirmed the results for current resources. The tangibility of assets has inverse proportional relationship with the leverage. As it is disintegrated in its main components, the significant and negative influence of machinery & equipment was more marked in the Industrial Goods sector. This result shows that, on average, the most specific assets from operating activities of a company compete for a less use of third party resources. As complementary results, it was observed that the leverage has persistence, which is linked with the static trade-off theory. Specifically for financial leverage, it was observed that the persistence is relevant when it is controlled for the lagged current assets classes variables. The proxy variable for growth opportunities, measured by the Market -to -Book, has the sign of its contradictory coefficient. The company size has a positive relationship with debt, in favor of static trade-off theory. Profitability is the most consistent variable in all the performed estimations, showing strong negative and significant relationship with leverage, as the pecking order theory predicts

Essays in Personal Transportation Demand and Consumer Finance

This dissertation is composed of three essays covering two areas of interest. The first topic is personal transportation demand with a focus on price and fuel efficiency elasticities of mileage demand, challenging assumptions common in the rebound effect literature. The second topic is consumer finance with a focus on small loans. The first chapter creates separate variables for fuel prices during periods of increasing and decreasing prices as well as an observed fuel economy measure to empirically test the equivalence of these elasticities. Using a panel from Germany from 1997 to 2009 I find a fuel economy elasticity of mileage of 53.3%, which is significantly different from the gas price elasticity of mileage during periods of decreasing gas prices, 4.8%. I reject the null hypothesis or price symmetry, with the elasticity of mileage during period of increasing gas prices ranging from 26.2% and 28.9%. The second chapter explores the potential for the rebound effect to vary with income. Panel data from U.S. households from 1997 to 2003 is used to estimate the rebound effect in a median regression. The estimated rebound effect independent of income ranges from 17.8% to 23.6%. An interaction of income and fuel economy is negative and significant, indicating that the rebound effect may be much higher for low income individuals and decreases with income; the rebound effect for low income households ranged from 80.3% to 105.0%, indicating that such households may increase gasoline consumption given an improvement in fuel economy. The final chapter documents the costs of credit instruments found in major mail order catalogs throughout the 20th century. This study constructs a new dataset and finds that the cost of credit increased and became stickier as mail order retailers switched from an installment-style closed-end loan to a revolving-style credit card. This study argues that revolving credit's ability to decrease salience of credit costs in the price of goods is the best explanation for rate stickiness in the mail order industry as well as for the preference of revolving credit among retailers.

Sino-African State Trading in Services: Added-Value through Angola-Model loaning, GATS commitments or FTAs?

Paper presented by Charlotte Sieber-Gasser at the 5th Annual TRAPCA Conference, Arusha (Tanzania), 25-26 November 2010. Despite the increasing volume of trade between China and African countries, not one single conventional free trade agreement (FTA) or economic partnership agreement (EPA) has yet been signed between an African country and China. Initially, Sino-African trade relations were to a very large extent centred on investments secured through bilateral investment agreements (BITs). The more recent Chinese investments on the African continent, however, are more informally based on FDI contracts with the state at the receiving end and a government-owned private company as the investor, or loosely attached to loans commonly known under term ‘the Angola-Model’. This rather unusual basis for economic integration and development assistance, outside the trodden path of free trade agreements and ODA, requires further analysis in order to understand how the current legal framework between China and the African continent impacts economic development and national sovereignty, and what kind of distributive consequences it may have.

The decline of ameriquest : a case study

In the subprime lending market, Ameriquest Mortgage Company is one of the leading lenders. It is widely known for its advertising slogan of “proud sponsor of the American dream.” Yet in 2006, an investigation into unlawful mortgage lending practices and the subsequent $325 million multi-State settlement brought even more attention to this company. What caused this lawsuit which brought irreparable damage to its reputation and financial loss for Ameriquest? This study focuses on the Information System Security management of the company. The study first introduces Ameriquest, and then briefly describes the lawsuit and settlement, and then discusses the IS security control in Ameriquest. The discussion will cover the internal control, external control, and technical controls of the company.

O ouro branco abre caminho: o algodão e a modernização do espaço urbano da Cidade da Parahyba (1850-1924)

The present research deals with the modernization process of the Cidade da Parahyba2, between 1850 and 1924, and its relation with the cotton economy, which represented the main source of wealth accumulation for both the private and the public sectors throughout the First Republic. This study on urban history was developed by focusing on the understanding of the city s spatial formation, and despite its emphasis on the economic aspects involved, other factors that also contribute to the development of the social life were not put aside. The modernization process of the Cidade da Parahyba was also analyzed during the period established for the study according to a chronological and thematic approach that established comparisons with the financial situation of the State, whenever this was necessary, with special attention to the contribution of the cotton economy to the State´s revenues. It was possible to detect a lack of financial help and loans from the federal and municipal administrations for finishing several public works already underway in the capital, since the federal funds allocated to the State of Parahyba do Norte were rather employed in emergency works against droughts and in agricultural development. One can then conclude that the financial resources required for the urban interventions were withdrawn from the State s treasury itself, resources that were collected mainly from activities such as cotton exportation and cotton trading. Another factor shows the interdependence between the urban remodeling and the cotton economy: during the years marked by great droughts or by hard plagues on the cotton plantations, cotton production decreased, as well as the State s finances. The first measures taken by the State s administrators were to halt all projects of urban remodeling in progress in the Cidade da Parahyba, which was, clearly, the most privileged city by the State s presidents during the period analyzed. 2 The city of João Pessoa was named Cidade da Parahyba, a designation that remained until September 1930, when it received its present-day name in order to pay homage to the president of the State, João Pessoa Cavalcanti de Albuquerque, murdered in the city of Recife in August of that same year. At that time, the State of Paraíba was known as Parahyba do Norte. Since this work is limited to a period of time comprised within the First Republic, the names employed respect the terms used in those days
