We analyze the determinants of adolescent motherhood and its effect on high school attendance and completion in a developing country setting. Using eight repeated rounds of Chilean household surveys that span the 1990 – 2006 period, we analyze the role of individual, family and community characteristics in determining teen motherhood. Our regression results reveal that adolescents who were born...

Competition for foreign direct investment (FDI) among developing countries has intensified in recent years. Using a sample of 68 developing countries across dif ferent regions, with data from 1975-2005, this paper investigates whether Latin America and the Caribbean (LAC) dif fers from non-LAC regions in regard to determinants of FDI; the evidence suggests that there are dif ferences. In partic...

the mono-metallic and bi-metallic catalysts have been prepared by impregnating with solutions containing a compound of h2ptcl6,wo3 and 1ml hcl (0.1 mol). it should be noted that the catalysts’ activity and selectivity have been determined under these conditions : 450-5000c ,and 15-25atm by h2. for converting n-heptane , the molar ratio h2/c7h16 is 5 , and lhsv is 1.5ml/h. it has been proved tha...

I study the problem of social learning in a model where agents move sequentially. Each agent receives a private signal about the underlying state of the world, observes the past actions in a neighborhood of individuals, and chooses her action attempting to match the true state. Existing literature shows that with unbounded private beliefs, asymptotic learning occurs if and only if agents observ...

News reports that carry positive or negative sentiment about a firm influence the firm’s stock price performance. This study examines the role of firm controllable marketing factors, namely, advertising spending and marketing capability, in moderating the relationship between news stories and firm stock returns. Drawing on a large panel data sample of over 7000 firmmonth observations, the resul...

This paper empirically explores the determinants of corporate research and development (R&D) intensity in the Canadian context with a sample of 134 TSE companies. Specifically we investigate in cross-section the impact of various governance and firm-specific variables on firms’ R&D intensity. We find that, in the case of governance variables, percentage of inside director, Directors’ ownership,...

In this paper, we consider estimation of a time-varying parameter model for a forwardlooking monetary policy rule, by employing ex-post data. A Heckman-type (1976) two-step procedure is employed in order to deal with endogeneity in the regressors. This allows us to econometrically take into account changing degrees of uncertainty associated with the Fed's forecasts of future in°ation and GDP ga...

This paper asks whether the level of integration of world countries in the international network of temporary human mobility can explain differences in their per-capita income and labor productivity. We disentangle the role played by global country centrality in the network from traditional openness measures, which only account for local, nearestneighbor linkages through which ideas and knowled...

The literature relates human capital costs to firm leverage (Berk, Stanton, and Zechner (2010) and Chemmanur, Cheng, and Zhang (2013)) and mergers and acquisitions (Lee, Mauer, and Xu (2017)). In this paper, we study the relation between a firm’s human capital costs and investment policy. We first present a simple theoretical setting to illustrate the positive effects of risky investment on ave...
