We consider an incumbent firm and a more efficient entrant, both offering a network good to several asymmetric buyers. The incumbent disposes of an installed base, while the entrant has a network of size zero at the outset, and needs to attract a critical mass of buyers to operate. We analyze...

Indirect assessments of market conduct have become widespread in the New Empirical Industrial Organization-NEIO literature. Recently, Steen and Salvanes (1999) provided a flexible dynamic econometric formulation of the approach advanced by Bresnahan (1982) and Lau (1982). The present paper...

This paper generalizes Benhabib and Farmer [4], by allowing for a strictly positive time-to-build of capital. The introduction of a time-to-build delay yields a system of mixed functional di¤erential equations. We show that the system has a unique steady state. More important, we prove that the...

This paper brings together several important strands of the econometrics literature: errorcorrection, cointegration and dynamic factor models. It introduces the Factor-augmented Error Correction Model (FECM), where the factors estimated from a large set of variables in levels are jointly...

If demand for human services is inelastic or manufactured goods are necessities, labour shifts from manufacturing to services and the budget share of services rises. Higher productivity growth in the market sector pushes up the tax rate and public employment if private goods and public services...

This paper examines the interaction between monetary and budgetary policy. A comparison of the dynamic responses in di.erent exchange rate regimes offers an assessment of the monetary union case. The analysis proceeds on an SVAR-common trends model. In its current specification, we can only...

Domeij and Klein (2005) have shown that the welfare gains of an optimal capital and labor income tax reform decline the longer the reform is pre-announced before its implementation. In other words, pre-announcement is costly in terms of welfare. I reexamine their claim by taking two additional...

This paper develops an asymptotic estimation theory for nonlinear autoregressive models with conditionally heteroskedastic errors. We consider a functional coefficient autoregression of order p (AR(p)) with the conditional variance specified as a general nonlinear first order generalized...

In this paper we propose a new GARCH-in-Mean (GARCH-M) model allowing for conditional skewness. The model is based on the so-called z distribution capable of modeling moderate skewness and kurtosis typically encountered in stock return series. The need to allow for skewness can also be readily...

Existing methods of reconstructing historical Euro-zone data by aggregation of the individual countries' data raises numerous difficulties due to past exchange rate changes. The approach proposed here is designed to avoid such distortions, and aggregate exactly when exchange rates are fixed. In...
