In this paper we use the property that certainty equivalence, as implied by a first-order approximation to the solution of stochastic discrete-time models, breaks in its equivalent continuous-time version. We study the extent to which a first-order approximated solution built by perturbation...

The quasi-linear quadratic utility model is widely used in economics. The knowledge of its exact origin is less widespread. A first contribution of the paper is to explain the genesis of this model. Next, we review the main properties of the general model, mainly following the previous...

We consolidate alternative ways for identifying stable and stressful scenarios in the S&P 500 market to construct contagion tests for recipient markets vulnerable to disturbances from this source market. The S&P 500 is decomposed into discrete conditions of: (1) Tranquil versus turbulent...

We analyze the effects of optimism and overconfidence when the manager’s compensation package includes severance pay and the CEO has bargaining power. We find that optimism does not affect incentive pay but increases severance pay with a negative effect on profit. Overconfidence, on the...

Can culture explain persistent differences in economic activity among individuals and across regions? A novel measure of cultural origin enables us to contrast the entrepreneurial activity of individuals located in the same municipality but whose ancestors lived just on opposite sides of the...

How effective are “smart” sanctions in imposing costs on an adversary? We consider this question in a model where a targeted regime may choose to “shield” strategically important firms from harm. Using detailed firm and individual data, we estimate the impact on firm performance from...

Using a long-panel dataset of Japanese firms that contains firm-level sales forecasts, we provide evidence on firm-level uncertainty and imperfect information over their life cycle. We find that firms make non-negligible and positively correlated forecast errors. However, they make more precise...

We examine the impact of fintech start-ups on the performance and default risk of traditional financial institutions. We find a positive relationship between fintech start-up formations and incumbent institutions’ performance for the period 2005–2018 and a large sample of financial...

We investigate the relationship between oil prices and stock markets of selected oil importers and oil exporters at the time of the COVID-19 pandemic. We provide evidence in favour of energy contagion, in term of significantly higher correlations between oil and stock markets returns during...
