Consumption of a good typically diminishes the marginal utility of consuming more, but for how long? This paper adapts a model of consumption capital to allow consumption to have a lasting effect that diminishes the marginal utility of future consumption. Estimates of the model find that it...

The paper presents a revision of the contemporary reductionistic demand theory, replacing the studying object, i.e. an individual, with a fuzzy collection of market buyers, regarded as a “statistical ensemble of consumers”. The new holistic market demand theory formally retains the...

The effects of a transatlantic trade agreement on the global forest sector were assessed with the Global Forest Products Model, conditional on previous macroeconomic impacts predicted with a general equilibrium model. Comprehensive tariff elimination per se had little effect on the forest...

Inventory inaccuracy is common at retailers. At many retailers, a cash register records incoming orders and outgoing sales, but not the demand or the shrinkage. The shrinkage refers to spoilage or pilferage of inventory. The demand differs from the sales in the periodic-review lost-sales...

We consider the production and admission control of a two-stage manufacturing system where intermediate components are produced to stock in the first stage and an end-product is assembled from these components through a second stage assembly operation which may allow backorders. The...

Optimal control theory is employed to derive explicitly the optimal (profit maximizing) price of a durable new product over time. The sales rate dynamics depends on the product price and on the unsold portion of the market. Specifically, the hazard rate (i.e. the probability of a purchase by a...

Due to differences in the effectiveness and side effects of different drugs, uncertainty is an important component of prescription drug choice. This uncertainty can cause patients and doctors to experiment with different drugs until they find a good match. In this paper, we specify and estimate...

Markov-modulated processes have been used in stochastic inventory models with setup costs for modeling demand under the influence of uncertain environmental factors, such as fluctuating economic and market conditions. The analyses of these models have been carried out in the literature only...

Natural and anthropogenic disasters frequently affect both the supply and demand side of an economy. A striking recent example is the COVID-19 pandemic which has created severe industry-specific disruptions to economic output in most countries. Since firms are embedded in production networks,...
