Current Account Adjustment: Some New Theory and Evidence

This paper aims to provide a theory of current account adjustment that generalizes the textbook version of the intertemporal approach to current account and places domestic labor market institutions at the center stage. In general, in response to a shock, an economy adjusts through a combination of a change in the composition of goods trade (i.e., intra-temporal trade channel) and a change in the current account (i.e., intertemporal trade channel). The more rigid the labor market, the slower the speed of adjustment of the current account towards its long-run equilibrium. Three pieces of evidence are provided that are consistent with the theory.

A Solution to Two Paradoxes of International Capital Flows

International capital flows from rich to poor countries can be regarded as either too small (the Lucas paradox in a one-sector model) or too large (when compared with the logic of factor price equalization in a two-sector model). To resolve the paradoxes, we introduce a non-neo-classical model which features financial contracts and firm heterogeneity. In our model, free trade in goods does not imply equal returns to capital across countries. In addition, rich patterns of gross capital flows emerge as a function of financial and property rights institutions. A poor country with an inefficient financial system may simultaneously experience an outflow of financial capital but an inflow of FDI, resulting in a small net flow. In comparison, a country with a low capital-to-labor ratio but a high risk of expropriation may experience outflow of financial capital without compensating inflow of FDI.

Domestic Institutions and the Bypass Effect of Financial Globalization

This paper proposes a simple model to study the relationship between domestic institutions - financial system, corporate governance, and property rights protection - and patterns of international capital flows. It studies conditions under which financial globalization can be a substitute for reforms of domestic financial system. Inefficient financial system and poor corporate governance in a country may be completely bypassed by two-way capital flows in which domestic savings leave the country in the form of financial capital outflows but domestic investment takes place via inward foreign direct investment. While financial globalization always improves the welfare of a developed country with a good financial system, its effect is ambiguous for a developing country with an inefficient financial sector/poor corporate governance. However, the net effect for a developing country is more likely to be positive, the stronger its property rights protection. This is consistent with the observation that developed countries are often more enthusiastic about capital account liberalization around the world than many developing countries. A noteworthy feature of this theory is that financial and property rights institutions can have different effects on capital flows.

On the Connections between Intertemporal and Intra-temporal Trades

This paper develops a new theory of international economics by introducing Heckscher-Ohlin features of intra-temporal trade into an intertemporal trade approach of current account. To do so, we consider a dynamic general equilibrium model with tradable sectors of different factor intensities, which allows for substitution between intertemporal trade (current account adjustment) and intra-temporal trade (goods trade). An economy's response to a shock generally involves a combination of a change in the composition of goods trade and a change in the current account. Flexible factor markets reduce the need for the current account to adjust. On the other hand, the more rigid the factor markets, the larger the size of current account adjustment relative to the volume of goods trade, and the slower the speed of adjustment of the current account towards its long-run equilibrium. We present empirical evidence consistent with the theory.

When Is Quality of Financial System a Source of Comparative Advantage?

Does finance follow the real economy, or the other way around? This paper unites the two competing schools of thought in a general equilibrium framework. Our key result is that there are threshold effects defined by a set of deep institutional parameters (cost of financial intermediation, quality of corporate governance, and level of property rights protection) which can be used to separate economies of high-quality institutions from those of low-quality institutions. On one hand, for economies with high-quality institutions, the view that finance follows the real economy is essentially correct. Equilibrium output and prices are determined by factor endowment. Further improvement in the institutions does not affect patterns of output. On the other hand, for economies with low-quality institutions, the view that finance is a key driver of the real economy is essentially correct. Not only is finance a source of comparative advantage, but an increase in capital endowment has no effect on outputs and prices. Our model extends a standard one-sector, partial equilibrium model of corporate finance to a multi-sector, general equilibrium analysis. Surprisingly, but consistent with data, we show that the size of financial markets (relative to GDP) does not change monotonically with either the quality of institutions or with the factor endowment. Free trade may reduce the aggregate income of an economy with low-quality institutions. Financial capital tends to flow from economies with low-quality institutions to those with high-quality institutions.

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
