An econometric model of tenure choice and demand for housing as a joint decision

This paper models a household's choice of tenure and demand for housing services as a joint decision imposing the restriction that both discrete and continuous decisions are derived from a single preference ordering. The utility index for households is the translog form of the reciprocal indirect utility function allowing for random preferences. Each household chooses between the two main tenures, the owner-occupied and subsidised rental sectors, but households may be rationed in either or both of these sectors and refused admission, in which case they are assumed to enter the third sector, uncontrolled rental. The model is estimated on UK data for 5895 households.     

Localization of a demand for nursing model at the grassroots level

A major obstacle to the development of a usable demand model for nursing is the standardization of the definition for "demand." The lack of standardization of economic terms which are utilized in the state demand models is contributing to the failure of the long-range forecasting process for nursing nationwide. Any state that chooses to utilize U.S. Department of Health and Human Services' Health Resources and Services Administration data has selected a model which is invalid due to failure to include all members of the nursing population since this definition excludes LPNs completely. Likewise, state nursing demand models in California, Pennsylvania, North Dakota, New Jersey, and the District of Columbia have similar disadvantages. Only at a localized county-by-county grassroots level can a nursing demand model be translated into an equation which would actually calculate demand for nursing.     

An analysis of the demand for skill in a growing economy

We construct a trade theoretic model of skill formation with skill as a produced intermediate input. Capital is required for production as well as for education which transforms unskilled labor into skilled. We use this model to reflect analytically on India's rising requirement of skilled manpower. We show that even if growth of capital and supply of skilled manpower match, relative stagnation of unskilled manufacturing sector will magnify the gap between growth in demand and supply of skill. This may happen, for example, if there is a vast pool of workforce who may not have even the basic education to qualify as “unskilled” and excessive capital flows into the skilled sector. Thus a country with lack of education at a very basic level will be forced to import skilled manpower from the rest of the world.     

The Endogenous Sequential Probit model: An application to the demand for hospital utilization

This paper develops the Endogenous Sequential Probit model to analyze the effect of managed care on hospital utilization by adult married US population and finds that managed care gives disincentives to utilize hospital care relative to the standard indemnity plans.     

An analysis of the demand for housing attributes

This paper uses a two-step approach to estimate a system of structural demand equations for housing attributes. Estimation of a hedonic price regression, in the first step, yields implicit prices for housing attributes for the Toronto Metropolitan area in 1978, which are then used to estimate the expenditure share equations derived from the indirect translog utility function. Empirical results indicate that the composite housing attributes (used in the second stage model) are own-price elastic, while an examination of cross price relationships reveals that these attributes are reasonably substitutable.     

The time profile of public expenditure growth in India: An emprical investigation

Empirical tests confirm that the major social upheavals produced interfunctional and intrafunctional ‘displacements’ in government spending and thereby changed the character of public expenditure in India. There was a strong resurgence in the growth of public expenditure on social and development services; the State governments gained a greater role in this area in the post-disturbance period. Perhaps this could be inferred as a disturbance-generated ‘decentralization process’ giving a greater scope for the State governments in dealing with social and development services.     

Dynamic factor demand in a rationing model

In this paper, a dynamic decision model of the firm with a delayed adjustment of employment and investment is developed. Special attention is devoted to dynamic inefficiencies, i.e. underutilizations of the capital stock and labour hoarding. Market disequilibrium is introduced by allowing for a sluggish adjustment of wages and prices. The model of the firm is complemented by explicit aggregation, and the aggregate model is estimated for the FRG for the period 1960 to 1989. The empirical results reveal that dynamic adjustment constraints for employment and capital contributed to the persistence of unemployment in Germany in the 1980s.     

A varying-parameter emprical model of balance of payments determination under fixed exchange rates: results for the UK and West Germany

The post-war period and particularly the 1960s witnessed a marked increase in the degree of international capital mobility due to various factors. Empirical studies of international financial flows during the 1960s generally balance model of the external account is developed which structural instability. A portfolio balance model of the external account is developed which allows a varying level of capital mobility and which nests the pure monetary model (perfect capital mobility). The upshot is a varying-parameter empirical specification. This is estimated for the UK and West Germany using Kalman filtering techniques. The model performs well and indicates an upward trend in capital mobility over the period, particularly after 1968.     

A dynamic model of demand for Mediterranean tourism

A dynamic econometric model was specified in order to estimate tourism consumption changes by Northern European countries and the USA for major Mediterranean destinations. The model employed a flexible framework for modelling short-term dynamics as well as the long run effects of a range of variables of specific interest to the countries considered. The estimated model provided useful information for tourism demand. The income elasticities demonstrated considerable differences in tourism demand preferences between origin countries and between traditional and newly developing destinations. The own and substitute price elasticities indicated the importance of effective prices in determining tourism receipts of the destinations.     

Carbon tax simulations using a household demand model

The main objective of this paper is to analyse consumer response and welfare effects due to changes in energy or environmental policy. To achieve this objective we formulate and estimate an econometric model for non-durable consumer demand in Sweden that utilises micro- and macro-data. In the simulations, we consider two revenue neutral scenarios that both imply a doubling of the CO₂ tax; one that returns the revenues in the form of a lower VAT and one that subsidise public transport. One conclusion from the simulations is that the CO₂ tax has regional distribution effects, in the sense that household living in sparsely populated areas carry a larger share of the tax burden.     

R&D activity in a dynamic factor demand model

The focus of this paper is an econometric analysis of the determinants of private firms' R&D activities in the context of a general dynamic factor demand model. Besides the traditional production factors we treat technological knowledge, endogenously determined by R&D expenditures, as a further input factor. While labour and materials are assumed to be variable, capital and know-how are considered as quasi-fixed. The dynamic demand equations for labour, capital investment and R&D which are derived from an intertemporal cost minimisation are estimated for a panel data set of small and medium size German firms. The data covers the period between 1978 and 1982 and includes 408 firms. It turns out that R&D activity depends on the underlying production structure as suggested by neoclassical theory. In addition, by introducing firm specific effects, we can show that firm size and market concentration influence innovative behaviour in accordance with the Schumpeterian hypotheses.Paper presented at the Industrial Organization Conference at the Annual Meeting of the Austrian Economic Association, Vienna, June 24–26, 1992, the 7th Annual Congress of the European Economic Association, Dublin, August 29–31, 1992, and the 19th Annual Conference of the EARIE, Stuttgart, September 4–6, 1992. Helpful suggestions and comments were received from participants of these conferences as well as from seminar participants at Temple University, at the University of Augsburg, and at the fourth DFG workshop Marktstruktur und gesamtwirtschaftliche Entwicklung in Munich. We are particularly indebted to an anonymous referee for very helpful specific comments. Finally, we would like to thank Horst Albach for providing us with the panel data set. Financial support of the DFG is gratefully acknowledged.     

Sun,sand and September 11: a model of tourism demand for the Maldives

Tourism is a key source of income for many small island economies, and so it is important to understand its determinants in such countries. We estimate a tourism demand model for the Maldives’ five main source markets and find that, in addition to the usual foreign income and own price variables, the cost of travel and of visiting alternative destinations (often missing from studies of this nature) almost always have a significant role. In addition, the country’s own marketing efforts prove effective at influencing demand. Finally, we find evidence the War on Terror has persistently depressed demand from some markets.     

The supply and demand for imports and exports in a simultaneous model

Previous studies on the behaviour of aggregate exports and imports have tended to ignore the simultaneous relationship between quantity and price. This paper investigates the price responsiveness of export and import demand and supply in eight African countries. The results indicate that export demand price elasticities are smaller when the sample is African. The import supply and demand elasticities were found to be generally large. The Marshall–Lerner condition of balance of payment stability is found to be easily satisfied. A positively sloped function of export supply is found to exist for a majority of countries in the sample. The average time lag of export supply is found to be about a year. The disequilibrium model is found to be more appropriate for import demand, import supply and export supply.     

Determinants of demand for green products: An application to eco-label demand for fish in Europe

In this paper, we confront the theoretical motivations of the consumption of eco-friendly products and the factors influencing the European perceptions regarding the fact that “fish caught using an environmentally friendly technique may carry a special label”. We take advantage of the recent integration of non-economic elements in the microeconomic analysis of consumers' behavior in order to highlight the factors leading to their demand for green products. Thanks to an original European survey on seafood product carried out on more than 5000 consumers, we test the influence of intrinsic motivation, information, localization and socio-economic factors on the demand for an eco-label for fish.Our results show a significant connection between the desire for eco-labeling and seafood features, especially the freshness of the fish, the geographical origin of the fish and the wild vs farmed origin of the fish. Moreover, we prove the major role played by the fish price. We also demonstrate that the ecological issue regarding fisheries is highly connected to consumer information, intrinsic motivation and socio-economic status: the typical “green fish consumer” is a young woman, well educated, well informed on the state of marine resources and not very trusting of the regulation of the fisheries. Consumers who are aware of the importance of marine resource preservation have the same profile.     

Factor demand explanation in the COMET model

The COMET model is an interconnected set of 13 econometric country models, one for each member country of the European Economic Community and for some other countries as well. Within each country model demand for production factors, including energy, is explained by a multi-output/multi-input national production structure resulting in an internally coherent subset of four input equations, which allows for reasonably realistic dynamics and involves only a limited number of unknown coefficients, which are internationally comparable. The estimates display considerable similarity across countries, rather weak price responses, but relatively strong substitution between labour and capital.     

GMM estimation of a structural demand model for yogurt and the effects of the introduction of new brands

The demand structure for yogurt is assumed to be properly described by a one level nested logit model that is applied to aggregate market data. Given the presence of endogenous regressors, suitably lagged endogenous variables (Arellano and Bover in J Econom 68:29–51, 1995; Blundell and Bond in J Econom 87:115–143, 1998) are proposed as instrumental variables. The validity of this set of instruments is discussed and price elasticities and marginal costs are recovered from the demand estimates. Total welfare gains associated to the introduction of two new brands by the same manufacturer are finally computed. Prices and profits decreased and total welfare increased.
