This paper establishes a `turnpike theorem' for a closed linear model of production with a primitive input requirement matrix. Optimal programs of resource allocation have a `turnpike property' if the growth factor of every sector in the economy converges, in the long run, to a common value. The...

What is the origin of Strategic Management leading towards national Welfare planning, development and optimisation all over the World? This question opens a "Pandora's Box". It is significant that it is a key question to open up the knowledge of a world of ignorance, with some believing that...

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,...

One of the major changes in european electricity markets is - besides the increasing share of renewable infeed - the fact that previously independent market areas have been connected. Day-Ahead auctions are no longer done separately and available interconnector capacity are not always auctioned...

To address the need for a better understanding of cooperation, coordination and competition among transportation modes identified by various research studies, this paper sets out to analyze port-railroad relations of cooperation and coordination in the Brazilian case and the possible existence...

In this paper we present a method for calculating the entire hedge surface of a derivative who’s future underlying asset has been simulated by a market simulator for example with the Monte Carlo method. Our method is built from work on penalized filtering techniques and is applied on a grid of...

Neoclassical growth accounting is a methodology used to measure the contribution of different production factors to economic growth and to indirectly compute the rate of technological progress. This model assumes constant returns to scale and perfectly competitive factor markets, which implies...

A data processing procedure, DEA (Data Envelopment Analysis) is described as as an analytical tool in audit engagement. DEA receives data inputs from from financial statements of a plurality of clients, constructs efficiency frontiers and evaluates relative income efficiencies. DEA can be used...

The effective management of uncertainty and complexity in premium pricing and reserve accumulation processes provide new challenges to the decision- and policy- makers. In this regard, the implementation of complex mathematical tools and advanced statistical techniques is highly acquired. Over...
