Inflation in Sri Lanka has been one of the country’s major macroeconomic issues, especially since 1977. caused due to various factors. The present study analyses demand-driven factors inflation Lanka. time-series data is used identify such factors, applying ARDL technique determine long-run and short-run relationships during 1977-2019 sampling period. X. were real GDP, fiscal deficit, 91-days t...

We report on recent developments on stochastic chain modelling of inter-dependent network infrastructures. The problem is approached in the spirit of the Leontief tradition within the framework of the Inoperability Input/Output Modelling [6] where, instead of dealing with the sector products, inoperabilities are introduced to describe the status of the global system. A Markov Chain evolution la...

The problem of interval observer design is addressed for a class of descriptor linear systems with time delays. First, an interval observation for any input in the system is provided. Second, the control input is designed together with the observer gains in order to guarantee interval estimation and stabilization simultaneously. Efficiency of the proposed approach is illustrated by numerical ex...

In this paper, we present an interior-point path-following algorithm for computing a Leontief economy equilibrium, that is, an exchange market equilibrium with Leontief utility functions, which is known to be in the complexity class of PPAD-complete. It is known that an equilibrium corresponds to a solution of a system of complementarities, so we construct a homotopy to tackle this system. We p...

The effects of an intercountry transfer of purchasing power were first prominently discussed by Keynes (1929) and Ohlin (1929) in a debate concerning the secondary effects of such a transfer. In subsequent years several economists, including Pigou (1932), Metzler (1942), Samuelson (1952, 1954) and Johnson (1955), joined the debate. Throughout this debate, these writers all agreed that the trans...

Background Performance-based financing (PBF) is often proposed as a way to improve health system performance. In Benin, PBF was launched in 2012 through a World Bank-supported project. The Belgian Development Agency (BTC) followed suit through a health system strengthening (HSS) project. This paper analyses and draws lessons from the experience of BTC-supported PBF alternative approach – especi...

We present a novel approach to a relational database machine for processing knowledge bases. This approach is based on functional programming concepts in order to manage processor resources and memory resources with the theoretical neatness of functional computation. By using demand-driven evaluation as a driving method of functional. computation, parallelism can be exploited in executing relat...

This paper is concerned with a comparison of the treatment of fixed capital in some multisectoral models. First the dynamic Leontief model is investigated. Scrutiny shows that this model suffers from conceptual misconceptions which are due to restrictive assumptions concerning full capacity production and transferability of capital in place and due to the definition of technical coefficients. W...

Several common flexible functional forms are evaluated for Texas agricultural production utilizing three procedures. Nested hypothesis tests indicate that the normalized quadratic is the marginally-preferred functional form followed by the generalized Leontief. Predictive accuracy results are ambiguous between the generalized Leontief and the normalized quadratic. Statistical performance favors...
