The Power of Social Network Construction and Analysis for Knowledge Discovery in the Medical Referral Process

The social network model is powerful enough to provide for the analysis and study of a variety of application domains from daily life, including health care and health informatics. After the widespread appearance of automated tools capable of deriving and analyzing social networks, social network analysis (SNA) and mining in the health care domain has recently received considerable attention for its key role in understanding how various bodies within the health care system form communities and how they are socially connected with each other. This understanding helps enhance the organizational structures and process flows, among others. In this article, we show how SNA techniques can solve issues in the medical referral system in the Canadian health care system and the like, by analyzing the social network of general practitioners (GPs) and specialists (SPs). One of the main targets is to optimize the communication between GPs and SPs with hopes of decreasing the waiting time of patients to be seen by SPs. Various SNA and mining techniques are described and analyzed, backed by reporting some experimental results.     

Foreign Aid and the Quest for Poverty Reduction: Is Aid to Agriculture Effective?

Development statistics estimate that three quarters of the poor live in rural areas and most of them depend on agriculture and related activities for their livelihood. Consequently, research focusing on economic growth and poverty reduction has found that sustainable rapid transition out of poverty requires a special emphasis on the agricultural sector. This study contributes to the debate on aid effectiveness by disaggregating total aid into subcategories and specifically investigating the relationship between aid given to the agricultural sector and poverty reduction. If agricultural development is more effective in reducing poverty than some other types of development, then foreign aid directed towards agriculture may be more efficient in increasing the well‐being of the poor than aid directed to some other sectors or uses. Our analysis uses panel data for developing aid recipient countries to empirically test this relationship. We find a significant relationship between agricultural aid and poverty reduction in our estimates.     

Insider trading with product differentiation

This paper investigates the effect of product differentiation on the real and financial decisions of a publicly-owned firm, competing $\grave{a}$ la Cournot with another privately-owned firm. The results show that the degree of product differentiation affects the stock price coefficients (i.e. the market maker’s response to the real signal and to the total order flow signal) and the output of the publicly-owned firm. It also appears to have a detrimental effect on the manager’s profits and compensation scheme. The paper then proposes an extension of the benchmark model to incorporate Cournot and Stackelberg competition between two insiders in the financial market. The type of the financial competition adopted has also an effect on the results of the benchmark model that sometimes depend on the degree of product differentiation.     

Young Adults Living with their Parents and the Influence of Peers

This study examines the impact of peer behaviour on the living arrangements of young adults in the US using data from the National Longitudinal Study of Adolescent Health. We achieve identification by exploiting the differences in the timing of leaving the parental home among peers, the individual‐specific nature of the peer groups that are based on friendship nominations, and by including network and cohort fixed effects. Our results indicate that there are statistically significant peer effects on young adults’ decisions to leave the parental home. We discuss various mechanisms and confirm the robustness of our results through a placebo exercise.     

Development Aid to Agriculture and Economic Growth

The link between foreign aid and economic growth has been a controversial issue with no strong consensus so far. This paper argues that a possible reason why some studies may conclude that aid is ineffective in promoting economic growth might be that not all aid is given for development purposes (i.e. aid given for strategic considerations, humanitarian reasons or emergency relief). This study classifies foreign aid into four subcategories: agricultural aid, social infrastructure aid, investment aid, and non‐investment aid. Using the generalized method of moments (GMM) estimation technique on a Barro type growth regression with panel data from the aid recipient economies, this paper finds that when aid is directed to the agricultural sector of the developing countries, it is positively and significantly related to growth and can affect economic growth in the short run.     

Understanding the institutional challenges and impacts of higher education reforms in Indonesia

ABSTRACT

This paper contributes to the academic literature on policy-making at the global level by empirically showing the nature and institutional challenges of higher education reforms under NPM principles. The authors explain the key strategies adopted by Indonesia’s government and the problems it faced in reforming its higher education system. The overall result was negative. The Indonesian reforms will not bring about meaningful outcomes unless the existing institutions, and the environment in which they operate, are also reformed.     

To liberalize or not to liberalize: Political and economic determinants of financial liberalization

Using a sample of 70 emerging market and developing countries, we examine the political and economic factors which affect the government's decision to liberalize the domestic equity markets. We document that the levels of industrialization and financial development, the quality of investor protection, and the level of the government's involvement in the economy are closely associated with the stock market liberalization decision. Furthermore, we find a positive and significant relation between the amount of foreign financial aid received by the governments in emerging market countries and the probability of stock market liberalization.     

The Inherited Inequality: How Demographic Aging and Pension Reforms can Change the Intergenerational Transmission of Wealth

The role of inherited wealth in modern economies has increasingly come under scrutiny. This study presents one of the first attempts to shed light on how demographic aging could shape this role. It shows that, in the absence of retirement annuities, or for a given level of annuitization, both increasing longevity and decreasing fertility should reduce the inherited share of total wealth in a given economy. Thus, aging is not likely to explain a recent surge in this share in some advanced economies. Shrinking retirement annuities, however, could offset and potentially reverse these effects. The paper also shows that individual bequests will be more unequally distributed if aging is driven by a drop in fertility. In comparison, the effect of increasing longevity on their distribution is non‐monotonic.
