Neuware - The enhanced access of developing countries to the international financial market since the seventies has been characterized by boom-bust cycles of unfettered external borrowing followed by abrupt financial crises. The first chapter analyzes the macroeconomic effects of volatile capital flows to a developing country. The analysis shows that investment, consumption, and the current account deficit depend positively on the expected availability of external finance. If international investors may unexpectedly decide to reduce their exposure to financial assets issued by the country, the optimal cost of external borrowing should exceed the interest rate paid by domestic residents in the international financial market. In the absence of insurance markets for this type of risk, a tax on capital inflows can be optimal.Recent endogenous growth models characterize a firm's technology as a commodity which is both partly excludable and associated with some production inputs, such as human capital and equipment. The second chapter explores the nature of the link between equipment investment and technology at the plant level in a large sample of Colombian manufacturing establishments. The results support the endogenous growth model's notion that technology is associated with the production inputs. Larger plants that invest more in machinery and equipment and employ higher levels of human capital tend to be more efficient.Models of investment with non-convex costs of adjustment predict that microeconomic time series of investment may be characterized by infrequent investment spurts and prolonged periods of little or no investment. In the third chapter I study the pattern of investment at the plant level in different categories of capital goods. As in the U.S., plant-level investment in Colombia is lumpy, and the probability of observing a large investment episode depends positively on the time elapsed since the latest large investment episode. As a contribution to the literature, I propose and implement two alternative econometric methods for the estimation of a simple model of irreversible investment. The results show that increases in the real exchange rate (pesos per dollar) have a consistently negative effect on investment, regardless of the type of capital good.

Neuware - Traditional theories of property rights change have posited an evolutionary progression of property rights towards private property in response to changes in the relative price ratio of land compared to the other factors of production. Using case studies from two areas of Ethiopia and one area of Eritrea the dissertation demonstrates the role of political factors such as interest group preference and state intervention in directing property rights development away from a linear path. The case studies trace the development of three separate systems of property rights throughout the twentieth century up to the Ethiopian revolution of 1974. Analysis of history and litigation in the three areas demonstrates that in none did property rights evolve spontaneously towards privatization. In one area of the study relative price changes did not lead to changes in the system of property rights as the theory predicts. In the other two areas, changes in property rights followed a change in the relative price of land, but these changes were brought about exogenously, by the intervention of the government or interest groups in guiding property rights in a particular direction. There are two theoretical conclusions to the study 1) property rights development does not always occur when we expect it to, other factors such as vested interests and government reluctance can intervene with their development and 2) even if property rights do change in response to relative price changes, they may not always move towards privatization or greater specification. In addition, one interesting empirical result of the research was that in communal systems of land tenure the transaction costs of land transfer are higher, leading to a drag on economic efficiency in the overall economy of the region. Generally, the incorporation of political factors into the model of changing property rights leads to a less parsimonious, but more accurate description of the progression of land rights in developing countries in particular.
