I began this thesis because I was confused about economics. I wondered why there were so many different models. I didn't understand how they fit together. I was also confused by the assumptions being made. For instance, the assumption that humans are rational utility-maximizers did not seem to agree with my own experiences. With my director Dr. Edward Schlee's help, my thesis has become an inquiry into the state of economic methodology, both in theory and in practice. The questions that drive this paper are: How do economists choose between theories? What is the purpose of economic theory? What is the role of empirical data in assessing models? What role do assumptions play in theory evaluation, and should assumptions make sense? Part I: Methodology is the theoretical portion of the paper. I summarize the essential arguments of the two main schools of thought in economic methodology, and argue for an updated methodology. In Part II: A case study: The expected utility hypothesis, I examine methodology in practice by assessing a handful of studies that seek to test the expected utility hypothesis. Interestingly, I find that there is a different between what economists say they are doing, and what they actually seem to be doing. Throughout this paper, I restrict my analysis to microeconomic theory, simply because this is the area with which I am more familiar. I intend this paper to be a guide for my fellow students and rising economists, as well as for already practicing economists. I hope it helps the reader better understand methodology and improve her own practice.

This dissertation consists of two essays that deal with the development of open developing economies. These economies have experienced drastic divergence in terms of economic growth from the 1970s through the 2010s. One important feature of those countries that have lagged behind is their failure to build up their domestic innovation capacity.

Abstract The first chapter discusses the policies that may have an impact on the long-run innovation capacity of developing economies. The existing literature emphasizes that the backward linkage of foreign-owned firms is a key to determining whether FDI is beneficial or detrimental to a domestic economy. However, little empirical evidence has shown which aspects of FDI policies lead to a strong backward linkage between foreign-owned and domestic firms. This paper focuses on the foreign ownership structure of these foreign-owned firms. I show that joint ventures (i.e, firms with 1%-99% foreign share) have stronger backward linkages than MNC affiliates (i.e, firms with 100% foreign share) with domestic firms. I also find that the differences in backward linkages are strong enough to translate into a positive correlation between domestic innovation and the density of joint ventures and a negative correlation between domestic innovation and the density of MNC affiliates. Finally, I find that the channel through which foreign ownership structure affects domestic innovation raises innovation TFP in domestic firms. My results suggest that policies that affect the foreign ownership structure of foreign-owned firms could have a persistent effect on domestic innovation because they shift the comparative advantage of an developing economy towards the innovation sector in the long run.

Abstract The second chapter provides a unified theory to study what causes the divergence in economic growth of developing economies and how the innovation sector emerges in the developing countries. I show that open developing economies become trapped at the middle-income level because they tend not to specialize in sectors that generate spillover or factor accumulation (the innovation sector). Using a dynamic Heckscher-Ohlin (H-O) model, I show that the fast growth of developing economies tends to end before they can fully catch up with the developed world, and the innovation sector will not operate in the developing countries. However, the successful growth stories of Korea and Taiwan challenge this view. In order to explore the economic miracle that happened in Korea and Taiwan, I generalize a dynamic Heckscher-Ohlin (H-O) model by introducing technology adoption and explore how it generates spillovers to domestic innovation. I show that countries with policies that encourage technology adoption will benefit most from FDI: in addition to the fact that foreign technology raises productivity in the host country, the demand for skilled labor to adopt these technologies raises the education level in equilibrium, which benefits domestic innovation and leads to catch-up in the long run.

Prior research on consumer behavior in health insurance markets has primarily focused on individual decision making while relying on strong parametric assumptions about preferences. The aim of this dissertation is to improve the traditional approach in both dimensions. First, I consider the importance of joint decision-making in individual insurance markets by studying how married couples coordinate their choices in these markets. Second, I investigate the robustness of prior studies by developing a non-parametric method to assess decision-making in health insurance markets. To study how married couples make choices in individual insurance markets I estimate a stochastic choice model of household demand that takes into account spouses' risk aversion, spouses' expenditure risk, risk sharing, and switching costs. I use the model estimates to study how coordination within couples and interaction between couples and singles affects the way that markets adjust to policies designed to nudge consumers toward choosing higher value plans, particularly with respect to adverse selection.

Finally, to assess consumer decision-making beyond standard parametric assumptions about preferences, I use second--order stochastic dominance rankings. Moreover, I show how to extend this method to construct bounds on the welfare implications of choosing dominated plans.
