| Abstract: | The CAPM is the fundamental model for pricing financial securities. Nevertheless, the way it is proved in Finance textbooks can be fairly confusing, and more complicated than necessary; with an excessive use of figures at the expense of equations. In addition, depending on the Finance textbook, the set of assumptions that are supposedly needed to prove the CAPM may actually differ. This paper tries to provide an intuitive and straightforward proof of the CAPM and it also illustrates at which instances of the proof the traditional assumptions are actually needed. The main conclusion is that a much simpler version of the CAPM would possibly be as formidable and ingenious as the traditional one and yet, with a much more intuitive proof and fewer unrealistic assumptions. |

| Abstract: | This study examines the possible data-snooping bias as a competing explanation for the anomalies in the cross-section of stock returns. We posit that the exhaustive standalone searches for profitable strategies could lead to recommending spuriously predictive variables. In order to explore the severity of this problem, we use a multiple testing method to evaluate the profitability of portfolios constructed by these predictors. Our empirical analyses suggest that over half of the findings based on individual testing method are no longer statistically significant after we adjust for data-snooping bias. Excluding the micro-cap stocks before portfolios construction and applying the notion of economic significance in this study further weaken the evidence for predictability.

| Abstract: | We empirically evaluate the predictive power of money growth measured by M2 for stock returns of the S&P 500 index. We use monthly US data and predict multiperiod returns over 1, 3, and 5 years with long-horizon regressions. In-sample regressions show that money growth is useful for predicting returns. Higher recent money growth has a significantly negative effect on subsequent returns of the S&P 500. An out-of-sample analysis shows that a simple model with money growth as a single predictor performs as goods as the constant expected returns model, while models with several predictor variables perform worse than those simple models. |

| Abstract: | We study the factors behind split ratings in sovereign credit ratings from different agencies, for the period 1980-2015. We employ random effects ordered and simple probit approaches to assess the explanatory power of different macroeconomic, government and financial variables. Our results show that structural balances and the existence of a default in the last ten years were the least significant variables whereas the level of net debt, budget balances, GDP per capita and the existence of a default in the last five years were found to be the most relevant variables explaining rating mismatches across agencies. For speculative-grade ratings, we also find that a default in the last two or five years decreases the rating difference between S&P and Fitch. For the positive rating difference between S&P and Moody’s for investment-grade ratings, an increase in external debt leads to a smaller rating gap between the two agencies |

| Abstract: | We study how low interest rates in the United States affect risk taking in the market for cross-border corporate loans. Because banks tend to originate these loans with intent to sell to nonbank investors, we examine risk taking by the broad financial system. To the extent that actions of the Federal Reserve affect U.S. interest rates, our analysis provides evidence of cross-border spillover effects of U.S. monetary policy and highlights the global lending and risk-taking channels. We find that movements in the U.S. interest rates have an important effect on ex-ante credit risk of cross-border corporate loans, though the channels are different in the pre- and post-crisis periods. Before the crisis, banks made ex-ante riskier loans to non-U.S. borrowers in response to a decline in U.S. short-term interest rates, and, after it, banks and nonbanks originated such loans in response to a decline in U.S. longer- term interest rates. Economic uncertainty, risk appetite, and the U.S. dollar exchange rate appear to play a limited role in explaining ex-ante credit risk. Our results highlight the potential policy challenges faced by central banks in affecting credit risk cycles in their own jurisdictions. |

| Abstract: | Chile has a large but relatively illiquid stock market. Global factors such as global risk appetite and monetary policy in advanced economies are key cyclical determinants of liquidity in Chilean equities. Evidence from a cross-section of emerging markets suggests strong protection of minority shareholders can help improve stock market liquitidity. Currently, illiquid in Chilean may have to pay 3½ percent more as cost of equity. Corporate governance should be improved, namely through the adoption of a stewardship code. |
