A non-Gaussian multivariate regime switching dynamic correlation model for fi nancial asset returns is proposed. It incorporates the multivariate generalized hyperbolic law for the conditional distribution of returns. All model parameters are estimated consistently using a new two-stage...

Portfolio diversification of firms' controlling owners influences their firms' capital investment. Empirically, the effect of owners' portfolio diversification on their firms' investment levels is positive for publicly-traded firms and tends to be negative for privately-held ones. These findings...

We solve the problem of optimal inventory management for a CARA market-maker who faces proportional transaction costs and marking to market. Our model accommodates inventory shocks following an arbitrary compound Poisson process, and allows us to link the optimal policy to the moment-generating...

A large literature documents a positive correlation between a firm's sustainability or ESG policies and firm value. However, the exact mechanism through which this relation arises remains ambiguous and it is often hard to establish the direction of causation. In this paper we propose and test...

Are firms that are managed and owned by females-only appraised differently than those where genders mix at the top? To answer this question we study an instructive sample of 7,467 firms from 22 countries. We find that – when borrowing from banks – firms that are both managed and owned by...

Economic theories provide conflicting hypotheses on how wealth inequality affects entrepreneurial dynamism. To empirically investigate its impact, we construct local measures of household wealth inequality based on financial rents, home equity, and 1880 farmland. We identify its effects on...

Can local government spending spur entrepreneurial activity? To answer this question we study a setting where, around multiple pre-determined and non-manipulable thresholds, municipalities with lower tax revenues receive direct and different monetary grants from the national budget. Employing a...

Initial Coin Offerings (ICOs) provide a clean opportunity and rich data to study the contribution of analysts to the functioning of capital markets. The assessments of freelancing ICO analysts vary in quality and exhibit biases due to the reciprocal interactions of analysts with ICO team...

The paper proposes a framework for large-scale portfolio optimization which accounts for all the major stylized facts of multivariate financial returns, including volatility clustering, dynamics in the dependency structure, asymmetry, heavy tails, and nonellipticity. It introduces a so-called...

We report strong evidence that changes of momentum, i.e. "acceleration", defined as the first difference of successive returns, provide better performance and higher explanatory power than momentum. The corresponding Γ-factor explains the momentum-sorted portfolios entirely but not the reverse....
