In this short note, we prove by an appropriate change of variables that the SVI implied volatility parameterization presented in Gatheral's book and the large-time asymptotic of the Heston implied volatility agree algebraically, thus confirming a conjecture from Gatheral as well as providing a...

In many applications common in testing for convergence the number of cross-sectional units is large and the number of time periods are few. In these situations asymptotic tests based on an omnibus null hypothesis are characterised by a number of problems. In this paper we propose a multiple...

We study some measurement issues that arise when analyzing the long run behavior of the jth creative region's time t log output per creative class member (y_j(t)) when this region is part of an aggregate economy of j = 1, …, N creative regions. We focus first (second) on absolute (relative)...

Long-term regional convergence hypothesis is examined for 32 Mexican states in a regional growth model with poverty traps using a new dataset on regional income inequality for the period 1940-2011. Although zero-growth poverty trap hypothesis is rejected for 28 out of 32 states, the evidence...

The literature on economic growth in Latin America still presents mixed results. In the case of Mexico, the main findings show a similar pattern, highlighting the lower capacity of the southern and central states to take advantage of the export-oriented model. The present research analyses the...

Since globalisation accelerated in the early 1990s, income inequality has increased in most developed countries and in some middle-income countries, including China and India. Also, inequality has declined in most countries of Latin America and the Caribbean and in many Sub-Saharan African and...

We estimate the speed of income convergence for a sample of 196 European NUTS 2 regions over the period 1985-1999. So far there is no direct estimator available for dynamic panels with strong spatial dependencies. We propose a two-step procedure, which involves first spatial filtering of the...

Since the early 1990s, there has been a renaissance in the study of regional growth, spurred by new models, methods, and data. We survey a range of modeling traditions, and some formal approaches to the hard problem of regional economics; namely, the joint consideration of agglomeration and...

This paper suggests an empirical framework for analysing income distribution dynamics and cross-region convergence in the European Union of 27 member states, 1995-2003. The framework lies in the research tradition that allows the state income space to be continuous, puts emphasis on both shape...
