Purpose This paper explores which fundamental aspects of US insurance firms are significant factors in determining whether a firm will be a target or acquirer firm. Design/methodology/approach By focusing on 251 mergers and acquisitions (M&A) deals (119 target firms and 132 acquirer firms) over...

In the past several decades a new challenge has arisen, and it refers to the rapid demographic ageing of the population in developed and developing countries, quite opposite to the previous understanding of overpopulated planet. Increase in the older population brings its implications to...

Feature selection becomes a prominent method in the big data era. The logistic regression model is a wrapper method that provides better classification or prediction accuracy but it is computationally expensive. In this study, we propose the random subspace logistic regression where features are...

Quantile regression methods are increasingly used to forecast tail risks and uncertainties in macroeconomic outcomes. This paper reconsiders how to construct predictive densities from quantile regressions. We compare a popular two-step approach that fits a specific parametric density to the...

This paper proposes a linear categorical random coefficient model, in which the random coefficients follow parametric categorical distributions. The distributional parameters are identified based on a linear recurrence structure of moments of the random coefficients. A Generalized Method of...

We improve on the Instrumented Principal Component Analysis (IPCA) model developed in Kelly, Pruitt and Su (2019) by providing more efficient Generalized Least Square (GLS) estimators with a closed-form limiting distribution allowing for a more consistent (mis)pricing inference. The IPCA model...

This paper proposes a dynamic regression model that incorporates network effects from a large cross section of units. We consider a functional coefficient to measure these effects that is estimated using Taylor expansions over a partition of disjoint intervals of the compact support of the...
