In the wake of the recent currency turmoil, the determinants of financial crises have come to the forefront of academic and policy debates. Applied to the MENA region, the objective of this article is to estimate the likely impact of the dynamics of liberalization on the financial stability. The...

This paper employs a parametric model of persistent (level) shifts in the conditional mean of stock market returns which are endogenously driven by large positive or negative return shocks. These shocks can be taken to reflect important market announcements, monetary policy regime changes and/or...

A class of nonlinear ARCH processes is introduced and studied. The existence of a strictly stationary and β-mixing solution is established under a mild assumption on the density of the underlying independent process. We give sufficient conditions for the existence of moments. The analysis...

The main goal of this study was to analyze the soybean price transmission between different cities of MatoGrosso – MT, Brazil, considering the existence of transaction costs. This state was chosen due to its high production and soybeans processing capacity. In order to capture the...

This article builds on the recent policy diffusion literature and attempts to overcome one of its major problems, namely the lack of a coherent theoretical framework. The literature defines policy diffusion as a process where policy choices are interdependent, and identifies several diffusion...

Asymmetric effects in a monetary policy rule could appear due to asymmetric preferences of the central bank or/and due to nonlinearities in the economic system. It might be suspected that monetary authorities are more aggressive to the inflation rate when it is above its target level than when...

This discussion focuses on threshold nonstationary–nonlinear time series modelling; it raises various issues to do with identifiability and model complexity. It also gives some background history concerning smooth threshold/transition autoregressive models and hidden Markov switching models....

Is the big push hypothesis consistent with capacity constraints in the study of aid effectiveness? Big push hypothesis suggests the existence of a minimum threshold below which aid is not effective, while the constraints referred to by the concept of absorptive capacity suggests the existence of...

A relação entre desigualdade e renda na forma de “U” invertido, conhecida como a hipótese de Kuznets, ainda é bastante controversa. Diversos trabalhos têm analisado os dados brasileiros, mas os resultados não são tão claros quanto a sua validade. Este artigo investiga essa relação...
