    Description: The goal of this paper is to evaluate the impact of the innovation promotion programs carried by the National Research and Innovation Agency (ANII). A combination of non-experimental methods was used to quantify the effects of public support to innovation in three dimensions of the firms' behavior: innova - tion investment, innovation results and economic performance. The results show evidence of crowding-in of public support to innovation. Also, beneficiaries of the programs show larger probability of successfully introducing new products and processes. We do not find impact in the economic performance indicators of the firms.

    Description: It is known that, when in the linear regression model there is a high degree of multicollinearity, the results obtained by using the Ordinary Least Squares (OLS) method are unstable. As a solution to this situation, in this paper we present the raised method, the ridge method and the orthogonal variables method as an alternative to the estimate by OLS. It is also shown that regression with orthogonal variables makes sense regardless of the existence of serious multicollinearity because it allows to answer questions which are not accessible when using the original model. These methodologies are applied to a data set of yields of treasury bills.

    Description: This paper introduces the use of graphs in the analysis of the determinants of tourists' expenditure, providing an alternative approach to the methods usually employed. Graph-based analysis is applied to study the behavior of cruise passengers arriving at the ports of Montevideo and Punta del Este in Uruguay. The graphical representation allows to synthesize and visualize the relationships between the set of variables that characterize tourists or tourist groups and the determinants of their level of spending. The graph-based methodology is particularly suitable to represent the dependency relationships among variables (between adjacent nodes) and conditional independence (between non-adjacent nodes). For the empirical application, individual data from the surveys of cruise passengers corresponding to the cruise season between November 2014 and April 2015 in Uruguay are considered. The existence of dependencies between spending variables and other variables that may be of interest (sociodemographic, contextual, etc.) is studied. The exercise shows that the variables that better explain visitors' behavior are linked to the port of disembarkation and the expenditure. The results also show that socioeconomic variables are not directly linked to spending.

    Description: The present paper estimates the effect over participation outcomes of the new reform to the pension system made in Chile in 2008, using a difference in difference matching estimation. The main results found that the treated group shows a higher withdrawal from the labor market and that they worked an average of 8 percentage points (pp) fewer months than the control group in 2009. The treated group also contributed 18 pp fewer months than the control group, and they have, on average, 6 pp more months in inactive status. Looking at the difference in per capita income, the treated group has an average of US$34 more per month than the control group in 2009.
