This paper analyses the forecasting power of weekly futures prices at Nord Pool. The forecasting power of futures prices is compared to an ARIMAX model of the spot price. The time series model contains lagged external variables such as: temperature, precipitation, reservoir levels and the basis...

This study investigates the citation patterns of theoretical and empirical papers over a period of almost 30 years, while also exploring the determinants of citation success. The results indicate that empirical papers attract more citation success than theoretical studies. However, the pattern...

This paper presents a simple model of optimal sustainable growth in which the environmental stock enters consumers' preferences and production possibilities depend upon the use of produced physical capital and the use of a flow of productive services provided through the exploitation of the...

This paper provides sufficient conditions under which the negotiated wage in unionized oligopolistic industries with centralized negotiations is independent of a number of product market features (such as the number of firms, the degree of product substitutability, or the type of market...

In this paper the climate change effect is an unforeseen earth temperature level above which a negative externality on technology and hence on society's welfare is exerted. We use a dynamic overlapping generations model to develop a positive analysis of the growth path of an economy with the...

This paper presents a micro-econometric model of the female labour market in Italy. The model is derived from a theoretical framework in which the labour market is assumed to be segmented, i.e. firms offer different labour contracts to different types of workers. In this context, female workers...

There are now quite many publications on the construction of an environmentally adjusted net-national product measure. Most of these publications base the discussion on rather ad hoc constructions of the national accounts. In this paper, I try to develop an accounting framework from basic...

We present estimates of inventory models based on firm level panel data and investigate whether over-simplified specification of the production technology may account for the frequent failure to find technological incentives to smooth production in the context of the standard linear-quadratic...
