Does homeownership promote wealth accumulation?

It is well known that homeowners are richer than renters, even after controlling for observable household characteristics. This is often used as an argument for policies that foster homeownership. However, the causal link between homeownership and wealth is difficult to establish due to many potential sources of endogeneity. Utilizing the Household Finance and Consumption Survey for the Euro area, we correct for endogeneity by using inheriting the household’ s main residence as an instrument. The exclusion restriction is that conditional on the total amount of inheritance, inheriting a home affects the wealth position of the household only through homeownership. For the sample of inheritors we find that the local average treatment effect for households that inherit a home and stay homeowners is negative. Owning a home reduces riches due to sizable reductions in the net holdings of financial and other real wealth of the treated households.     

The dependence structure between the Canadian stock market and the USD/CAD exchange rate: a copula approach

Abstract This paper investigates the dependence structure between the real Canadian stock returns and the real USD/CAD exchange rate returns, using the Symmetrized Joe‐Clayton (SJC) copula function. We estimate the SJC copula with monthly data over the period 1995:1 to 2006:12. Our results show significant asymmetric static and dynamic tail dependence between the real stock returns and the real exchange rate returns, such that the two returns are more dependent in the left than in the right tail of their joint distribution. We explain this asymmetric dependence in terms of an asymmetric interest rate policy by Canadian monetary authorities in response to changes in the real exchange rate during sub‐periods of falling and rising commodity prices.     

On the complementarity of money and credit

I propose a model where agents choose to conduct their business using two payment instruments, money and bilateral credit. A friction in the timing of transactions rationalizes the use of both instruments and makes it optimal for agents to use money as a means of settlement for credit. Money and credit complement each other. With anticipated inflation, complementarity implies that the credit to money ratio decreases with inflation.     

Money, capital, and real liquidity effects with habit formation

Abstract.  The money in utility model is reconsidered in the presence of endogenous labour and habits. With standard assumptions about preferences and a policy rule that sets the nominal interest rate by adjusting the growth rate of money, the model exhibits superneutrality in the steady state. Nevertheless, habits give rise to real liquidity effects in the short run. After an increase in the nominal interest rate, employment falls, resulting in a fall in capital accumulation and in the short‐ and long‐term real interest rates. The adjustment of the capital stock is non‐monotonic. Employment and the short‐ and long‐term real interest rates may also adjust non‐monotonically. JEL classification: E22, E52, E58     

Imperfectly competitive cycles with Keynesian and Walrasian features

We consider a multi-sector overlapping generations model with oligopolistic firms in the output markets and wage-setting trade unions in the labour markets. A coordination problem between firms creates multiple temporary equilibria which are either Walrasian or of the Keynesian unemployment type. There exist many deterministic and stochastic equilibrium cycles fluctuating between Keynesian recession and Walrasian boom periods with arbitrarily long phases in each regime. The cycles are in accordance with certain empirical regularities. Money is neutral and superneutral, but appropriate countercyclical fiscal policies stabilize the cycles in a textbook Keynesian way.     

Service Firms Heterogeneity,International Collaborations and Export Participation

The paper investigates the relationship between service firms’ international collaboration strategies and export decision. It proposes an extension of the recent class of models of firm heterogeneity, intermediation and international trade according to which service firms can engage in a collaboration agreement with a foreign partner in order to favour their market access and distribution activities overseas. The paper analyses the empirical relevance of this model by means of a new survey dataset providing information on the internationalization activities of 814 Norwegian firms in the service sectors for the period 2004–2006. The econometric results point out that international collaboration, both on existing and on innovative services, is indeed an important factor to foster service firms’ decision to enter the export market.
