In this paper we propose a multivariate GARCH model with a time-varying conditional correlation structure. The new Double Smooth Transition Conditional Correlation GARCH model extends the Smooth Transition Conditional Correlation GARCH model of Silvennoinen and Teräsvirta (2005) by including...

We document a clear increase in Swedish earnings inequality in the early 1990s. Inequality in disposable income and earnings net of taxes and transfers also increased, but much less than the increased inequality in pre-government earnings. These different developments are most likely explained...

Vietnam has witnessed a dynamic restructuring of its non-state enterprises since the initiation of market reforms in the late 1980s. Based on the results of 371 private sector enterprises surveyed in 1991 and 1997, this paper analyses the transformation of one category of resurveyed enterprises...

This paper analyzes how bond option prices are affected by different types of monetary policy. Analytical results from a general equilibrium model with sticky wages show that employment or output targeting typically give lower bond option prices than inflation targeting.

Modelling multivariate failure times in a competing risks setting is often performed by assuming independence between risks. However, by wrongly assuming independence, seriously biased parameter estimates may result. The aim of this paper is to evaluate a test for independence previously...

Using detailed micro data from the Indonesian manufacturing sector, we examine the effect on productivity growth of different regional characteristics and direct foreign investment. The results suggest that a diversified regional industry sector increase productivity growth. Direct foreign...

The Ramsey optimal taxation theory implies that the tax rate on capital income should be zero in the long run. This result holds even if the social planner only cares about workers that do not hold assets, or if the planner only cares about any other group in the economy. This paper demonstrates...

This paper identifies the pertinent institutions governing the structure of payoffs with regard to female career progression. Drawing on recent insights in behavioral economics, we hypothesize that interactions between psychological mechanisms and the institutional setup may be important...

The cost-effectiveness of hormone replacement therapy (HRT) based on a societal perspective is reassessed based on new medical evidence found in the Women’s Health Initiative (WHI). Within a model framework using an individual state transition model the cost-effectiveness of 50-60 year old...

In this article, we derive a set of necessary and sufficient conditions for positivity of the vector conditional variance equation in multivariate GARCH models with explicit modelling of conditional correlation. These models include the constant conditional correlation GARCH model of Bollerslev...
