Equity-premium prediction: Attention is all you need

Predictions of stock returns are greatly improved relative to low-dimensional forecasting regressions when the forecasts are based on the estimated factor of large data sets, also known as the diffusion index (DI) model. However, when applied to text data, DI models do not perform well. This paper shows that by simply using text data in a DI model does not improve equity-premium forecasts over the naive historical-average model, but substantial gains are obtained when one selects the most predictive words before computing the factors and allows the dictionary to be updated over time.

The measurement of unemployment when unemployment is high

Are jobless persons who want work but are not actively searching, unemployed or out of the labour force? Previous research on this issue has focused on North America and used as the test whether the probability of transition to employment is similar for searching and non-searching jobless persons. This paper develops three new tests as to whether those not searching but wanting work are distinct from the searching unemployed. It asks: are non-searching persons richer, happier, and do they have a lesser impact on local wages, than the searchers? These tests are implemented using data from South Africa, a country in which unemployment is very high and where the treatment of non-searchers really matters for the understanding of poverty and labour market issues. The results favour the ‘discouraged worker’ view of the non-searching unemployed and the use of the broad, inclusive, measure of unemployment.

The first-order approach when the cost of effort is money

We provide sufficient conditions for the first-order approach in the principal-agent problem when the agent’s utility has the nonseparable form u(y−c(a))$u(y-c\left(a\right))$ where y$y$ is the contractual payoff and c(a)$c\left(a\right)$ is the money cost of effort. We first consider a decision-maker facing prospects which cost c(a)$c\left(a\right)$ and with distributions of returns y$y$ that depend on a$a$. The decision problem is shown to be concave if the primitive of the cdf of returns is jointly convex in a$a$ and y$y$, a condition we call Concavity of the Cumulative Quantile (CCQ) and which is satisfied by many common distributions. Next we apply CCQ to the distribution of outcomes (or their likelihood-ratio transforms) in the principal-agent problem and derive restrictions on the utility function that validate the first-order approach. We also discuss another condition, log-convexity of the distribution, and show that it allows binding limited liability constraints, which CCQ does not.     

罗凡：政策应更加公开、透明

我本人有近20年在外资企业工作的经验。我将20年前的外企称为“老式外企”,因为当时大多数外企进入中国的时间还很短,都没能实现本土化。当时的外企基本上没有实现本土化的可能性。因为当时中国人和外国人之间的文化差异非常大,中国人长期受计划经济的熏陶,无法理解市场是怎么一回事。在企业经营管理方面,与外国人很难沟通。
