Essays on the political economy of trade policy and economic *development

This dissertation studies the political economy of trade policy in a developing country, namely Turkey, under different economic and political regimes. The research analyzes the effects of these different regimes on the import structure, the trade policy and the industrialization process in Turkey and derives implications for aggregate welfare. ^ In the second chapter, the effects of trade liberalization policies on import demand are examined. Using disaggregated industry-level data, import demand elasticities for various sectors have been computed, analyzed under different economic regimes, and compared with those of developed countries. The results are statistically significant and reliable, and conform to the predictions of economic theory. Estimation of these elasticities is also a necessary ingredient for the third chapter of the dissertation. ^ The third chapter examines the predictions of the state-of-the-art “Protection For Sale” model of Grossman and Helpman (1994). Employing advanced econometric methods and a unique data set, strong support is found for the fundamental predictions of the model in the context of Turkey. Specifically, the government is found to attach a much higher weight to social welfare than to political contributions. This weight is higher under the democratic regime than under the dictatorship, a result potentially of interest to all researchers in the area of political economy. ^ The fourth chapter looks at the effects of industry concentration and import price shocks on protection, promotion and the choice of policy instruments in Turkey. In this context, it examines and finds support for the predictions of some well-known models in the literature. ^

Dynamic Performance Evaluation of Canadian Fixed-Income Funds using Markov Regime Switching Models

This thesis examines the performance of Canadian fixed-income mutual funds in the context of an unobservable market factor that affects mutual fund returns. We use various selection and timing models augmented with univariate and multivariate regime-switching structures. These models assume a joint distribution of an unobservable latent variable and fund returns. The fund sample comprises six Canadian value-weighted portfolios with different investing objectives from 1980 to 2011. These are the Canadian fixed-income funds, the Canadian inflation protected fixed-income funds, the Canadian long-term fixed-income funds, the Canadian money market funds, the Canadian short-term fixed-income funds and the high yield fixed-income funds. We find strong evidence that more than one state variable is necessary to explain the dynamics of the returns on Canadian fixed-income funds. For instance, Canadian fixed-income funds clearly show that there are two regimes that can be identified with a turning point during the mid-eighties. This structural break corresponds to an increase in the Canadian bond index from its low values in the early 1980s to its current high values. Other fixed-income funds results show latent state variables that mimic the behaviour of the general economic activity. Generally, we report that Canadian bond fund alphas are negative. In other words, fund managers do not add value through their selection abilities. We find evidence that Canadian fixed-income fund portfolio managers are successful market timers who shift portfolio weights between risky and riskless financial assets according to expected market conditions. Conversely, Canadian inflation protected funds, Canadian long-term fixed-income funds and Canadian money market funds have no market timing ability. We conclude that these managers generally do not have positive performance by actively managing their portfolios. We also report that the Canadian fixed-income fund portfolios perform asymmetrically under different economic regimes. In particular, these portfolio managers demonstrate poorer selection skills during recessions. Finally, we demonstrate that the multivariate regime-switching model is superior to univariate models given the dynamic market conditions and the correlation between fund portfolios.

Estructura a Plazo Colombia: Modelo Afín de tres factores

La estimación e interpretación de la estructura a plazo de la tasas de interés es de gran relevancia porque permite realizar pronósticos, es fundamental para la toma de decisiones de política monetaria y fiscal, es esencial en la administración de riesgos y es insumo para la valoración de diferentes activos financieros. Por estas razones, es necesario entender que puede provocar un movimiento en la estructura a plazo. En este trabajo se estiman un modelo afín exponencial de tres factores aplicado a los rendimientos de los títulos en pesos de deuda pública colombianos. Los factores estimados son la tasa corta, la media de largo plazo de la tasa corta y la volatilidad de la tasa corta. La estimación se realiza para el periodo enero 2010 a mayo de 2015 y se realiza un análisis de correlaciones entre los tres factores. Posterior a esto, con los factores estimados se realiza una regresión para identificar la importancia que tiene cada uno de estos en el comportamiento de las tasas de los títulos de deuda pública colombiana para diferentes plazos al vencimiento. Finalmente, se estima la estructura a plazo de las tasas de interés para Colombia y se identifica la relación de los factores estimados con los encontrados por Litterman y Scheinkman [1991] correspondientes al nivel, pendiente y curvatura.

Bancos públicos e desenvolvimento : análise de decisões judiciais e intervenção do Estado na economia

Esta dissertação tem o objetivo de estudar, entre diferentes modelos de organização econômica, aspectos da feição do arranjo financeiro brasileiro, com ênfase sobre os bancos públicos agentes de mercado no Brasil. A pesquisa está divida em uma etapa eminentemente jurídica, de sistematização e análise de normas e decisões judiciais; e uma leitura de economia política do contexto em que essas variáveis jurídicas estão inseridas. As normas pesquisadas analisam a constituição e o funcionamento do arranjo financeiro brasileiro, identificando elementos que constituem um maior protagonismo dos bancos oficiais no Sistema Financeiro Nacional, como, por exemplo, as funções de política econômica e mecanismos de poupança e depósito compulsórios. Entre outras normas, merecem destaque a Lei 4.595/64 e a Constituição Federal de 1988. A pesquisa de decisões judiciais, por sua vez, estuda o contexto e os principais argumentos de ações que envolveram um aspecto sensível na coexistência de bancos públicos e privados: a possibilidade de bancos oficiais depositarem e gerirem recursos em caráter de exclusividade. A leitura de economia política feita no segundo capítulo consiste em ampliar a lente de análise sobre o arranjo financeiro baseado em bancos públicos. Para tanto, serão analisados alguns modelos de organização econômica, divididos pela literatura de variedades de capitalismo em economias de mercado liberais e coordenadas. Ao interpretar esses modelos para o contexto econômico brasileiro, nota-se que o Brasil se valeu de mecanismos de coordenação distintos dos demais apresentados na literatura: uma coordenação pública da economia de mercado, enquanto alternativa para superar gargalos específicos do desenvolvimento econômico nacional. O Brasil, portanto, valendo-se de mecanismos de coordenação próprios, desenha o seu arranjo financeiro a partir de uma singularidade institucional: a possibilidade dos bancos oficiais poderem operar, exclusivamente, determinados recursos mesmo em uma economia de mercado; conta com mecanismos de coordenação eminentemente públicos, mas, ao mesmo tempo, deixando claro que existem mecanismos de mercado e concorrenciais estabelecidos e que devem ser observados. Essa dicotomia, entre bancos oficiais e privados, com um maior protagonismo dos bancos públicos em uma economia de mercado é que constitui, principalmente, essa singularidade institucional.

Economic Development under Alternative Trade Regimes

How does openness affect economic development? This question is answered in the context of a dynamic general equilibrium model of the world economy, where countries have technological differences that are both sector-neutral and specific to the investment goods sector. Relative to a benchmark case of trade in credit markets only, consider (i) a complete restriction of trade, and (ii) a full liberalization of trade. The first change decreases the cross-sectional dispersion of incomes only slightly, and produces a relatively small welfare loss. The second change, instead, decreases dispersion by a significant amount, and produces a very large welfare gain.

The Transitioning Economic Dynamics of the Military in Communist Regimes: A Comparison of Cuba, China and Vietnam [Student's Paper Series]

Several factors can increase or decrease military-economic involvement in communist regimes. This anomalous form of military behavior, labeled as the Military Business Complex (MBC), emerged in various communist regimes in the 1980s. However, in early 2000s, the communist governments of China and Vietnam began to decrease the number of military-managed industries, while similar industries increased in Cuba. This paper explains why military industries in Cuba have increased over the last two decades, while they decreased in the Chinese and Vietnamese examples. This question is answered by comparatively testing two hypotheses: the Communist Party and the Bureaucratic-Authoritarian (BA) Hypotheses. The Communist Party hypotheses helps explain how the historical and current structures of Party oversight of the military have been lacking in strength and reliability in Cuba, while they traditionally have been more robust in China and Vietnam. The BA hypotheses helps explain how, due to the lack of a strong civilian institutional oversight, the Cuban military has grown into a bureaucratic entity with many political officers holding autonomous positions of power, an outcome that is not prevalent in the Chinese and Vietnamese examples. Thus, with the establishment of a bureaucratic military government and with the absence of a strong party oversight, the Cuban military has been able to protect its economic endeavors while the Chinese and Vietnamese MBC regimes have contracted.

On dictatorship, economic development and stability

This paper aims to account for varying economic performances and political stability under dictatorship. We argue that economic welfare and social order are the contemporary relevant factors of political regimes' stability. Societies with low natural level of social order tend to tolerate predatory behavior from dictators in exchange of a provision of civil peace. The fear of anarchy may explain why populations are locked in the worst dictatorships. In contrast, in societies enjoying a relative natural civil peace, dictatorship is less likely to be predatory because low economic welfare may destabilize it.

Business Cycle Regimes in CEECs Production: A Threshold SURE Approach

We use a threshold seemingly unrelated regressions specification to assess whether the Central and East European countries (CEECs) are synchronized in their business cycles to the Euro-area. This specification is useful in two ways: First, it takes into account the common institutional factors and the similarities across CEECs in their process of economic transition. Second, it captures business cycle asymmetries by allowing for the presence of two distinct regimes for the CEECs. As the CEECs are strongly affected by the Euro-area these regimes may be associated with Euro-area expansions and contractions. We discuss representation, estimation by maximum likelihood and inference. The methodology is illustrated by using monthly industrial production in 8 CEECs. The results show that apart from Lithuania the rest of the CEECs experience “normal” growth when the Euro-area contracts and “high” growth when the Euro-area expands. Given that the CEECs are “catching up” with the Euro-area this result shows that most CEECs seem synchronized to the Euro-area cycle. Keywords: Threshold SURE; asymmetry; business cycles; CEECs.
