Nonlinear time series models, especially those with regime-switching and GARCH errors, have become increasingly popular in the economics and finance literature. However, much of the research has concentrated on the empirical applications of various models, with little theoretical or statistical...

Once you allow for persistence in macroeconomic variables, two aspects of exchange rate credibility emerge whose relative importance can vary over time. Hence, the effect of policy measures on interest rate differentials becomes ambiguous. In this paper, a Markov-switching VAR that allows for...

The existing literature on fiscal policy has mainly employed linear models that found a small fiscal multiplier in developing economies. These findings challenge the importance and e↵ectiveness of fiscal policy for these countries. However, linear models are not capable of distinguishing the...

The Fed's policy rule switches during the different phases of the business cycle. This finding is established using a dynamic mixture model to estimate regime-dependent Taylor-type rules on US quarterly data from 1960 to 2021. Instead of exogenously partitioning the data based on tenures of the...

It is commonly known that wholesale spot electricity markets exhibit high price volatility, strong mean-reversion and frequent extreme price spikes. This paper employs a basic stochastic model, a mean-reverting model and a regime-switching model to capture these features in the Australian...

En este trabajo se analiza la dinámica de propagación de las perturbaciones de los ciclos económicos regionales en Europa y se identifican sus principales factores subyacentes. Asimismo, se propone un nuevo método para medir la sincronización variable en el tiempo en muestras pequeñas, que...

Se propone una nueva medida de la inflación subyacente que informa, en tiempo real, sobre los riesgos asimétricos en las previsiones de inflación. Las asimetrías son generadas por no linealidades inducidas por la actividad económica. El nuevo indicador se basa en un modelo multivariante de...

The existing literature on fiscal policy has mainly employed linear models that found a small fiscal multiplier in developing economies. These findings challenge the importance and effectiveness of fiscal policy for these countries. However, linear models are not capable of distinguishing the...

This paper proposes and solves an optimal dividend problem in which a two-state regimeswitching environment affects the dynamics of the company's cash surplus and, as a novel feature, also the bankruptcy level. The aim is to maximize the total expected profits from dividends until bankruptcy....

In this paper, we consider a company that wishes to determine the optimal reinsurance strategy minimising the total expected discounted amount of capital injections needed to prevent the ruin. The company's surplus process is assumed to follow a Brownian motion with drift, and the reinsurance...
