Comovement in international equity markets: A sectoral view

Abstract We investigate shifts in correlation patterns among international equity returns at the market level as well as the industry level. We develop a novel bivariate GARCH model for equity returns with a smoothly time-varying correlation and then derive a Lagrange Multiplier statistic to test the constant correlation hypothesis directly. Applying the test to weekly data from Germany, Japan, the UK and the US in the period 1980–2000, we find that correlations among the German, UK and US stock markets have doubled, whereas Japanese correlations have remained the same. Both dates of change and speeds of adjustment vary widely across countries and sectors.

Bond market and stock market integration in Europe: a smooth transition approach

This article investigates whether there has been a structural increase in financial market integration in nine European countries and the US in the period 1980 to 2003. We employ a GARCH model with a smoothly time-varying correlation to estimate the date of change and the speed of the transition between the low and high correlation regimes. Our test produces strong evidence of greater comovement across the board for both stock markets and government bond markets. Dates of change and speeds of adjustment vary widely across country linkages. Stock market integration is a more gradual process than bond market integration. The impact of European monetary union (EMU) is rather limited, as it has mainly affected the timing of bond market correlation gains (but hardly their size) and has had little discernible effect on stock market integration.

Exchange rate pass-through in the Netherlands: has it changed?

This study assesses whether the degree of exchange rate pass-through in the Netherlands has changed during the run-up to Economic and Monetary Union. VAR models are estimated on rolling sample periods to show that the pass-through of changes in the guilder-mark exchange rate has increased, while the pass-through of changes in the guilder-pound and guilder-dollar have remained more or less stable. This supports the view that the Netherlands and Germany have become increasingly integrated. This is in contrast to Taylors (Economic Review 44, 1384–408, 2000) claim that the decline in inflation has been associated with a significant decline in the degree to which firms pass-through changes in costs.

Does deflation affect household spending? The case of the Netherlands

ABSTRACT This article investigates the impact of deflation on real private consumption and residential investment by Dutch households during the 1980–2013 period. We estimate theoretically founded consumption and investment equations and show that a fall in the general price level significantly negatively affects both growth in real consumption and residential investment. The impact on residential investment is more delayed, but stronger.
