This article seeks to check the nonlinearity of the Phillips curve in Tunisia for the 1993–2012 period, relying on a hybrid new Keynesian Phillips curve modeled via a Logistic Smooth Transition Regression (LSTR) model with endogenous variables. We estimate this model using the nonlinear...

This study examines whether a debt-to-GDP threshold exists in the public debt and economic growth relationship for 20 Middle East and North Africa (MENA) countries from 1990 to 2016 using the threshold estimation technique. The empirical results reveal that there is a threshold effect in the...

This paper studies the role of the exchange rate regime for trade of new products. It first provides VAR evidence that a rise in external productivity shifts trade away from new products and more so in fixed regimes. Then, it presents a model with firm dynamics in line with this evidence. We...

The purpose of this paper is to evaluate the behavior of monetary authorities in Tunisia and Egypt, in response to changes in macroeconomic variables over time based on LSTR model. In this sense, we estimate Taylor-type equations for short-term interest rate in Tunisia and Egypt using quarterly...

Corruption and inflation are two economic problems with serious social consequences. This paper analyzes the link between these two problems, focusing on the case of 19 prices observed for agricultural products in 90 countries since 2000. Using 'panel data cointegration' techniques, we conclude...

The external financing of fiscal deficit is key to bridging public revenue shortfalls within developing economies. However, the public expenditure responses to the incoming foreign financial assistances, as documented in the existing literature, depict ambiguity with respect to the nature of the...

This paper investigates the impact of the time-varying elasticity of the cyclically adjusted primary balance (CAPB) and fiscal consolidation on government debt. The time-varying parameter structural vector autoregression (TVP-VAR) model is used on a time series of data from 1979 to 2022. The...

Up until the 1980s, studies on corruption were dominated by disciplines of public administration and sociology. In the following years, however, economists have also provided a good amount of research on this issue. According to Transparency International Agency, corruption, which has a negative...

This paper investigates the effect of inflation volatility on private sector credit growth. The results indicate that private sector credit growth is positively linked to the one period lagged inflation volatility. Given that past monetary policy actions continue to affect the targeted variables...

Empirical studies of the global liquidity spillover on Indonesia's economy are still relatively limited. Most of the global contagion literature on Indonesia's economy focuses only on the effects of real shock (on output) due to financial shock. We assert that the effect of global output on...
