The linear quadratic (LQ) optimal control problem is studied for a partial differential equation model of a time-varying plug flow tubular reactor. First some properties of the linearized model around a specific equilibrium profile are studied. Next, an LQ-control feedback is computed by using the corresponding operator Riccati differential equation, whose solution can be obtained via a related...

We consider a discrete-time two-sector Cobb-Douglas economy with positive sector specific external effects and partial depreciation of capital. We show that local indeterminacy of steady states and cycles can easily arise with constant social returns to scale, and very small market imperfections. However these properties of equilibrium paths become less likely in the case of partial depreciatio...

the equilibrium solubility data of co2 in the various aqueous blends of triisopropanolamine (tipa) + monoethanolamine (mea) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oc and co2 partial pressures below 100 kpa. the experiments were done in an atmospheric gas absorption system and the amount of absorbed co2 was measured wi...

This paper develops and estimates a dynamic general equilibrium overlapping generations model of career decisions. The model is fit to data on life cycle employment, schooling and occupation decisions, and on life cycle labor earnings, within and between cohorts observed in the US between 1968 and 1993. Based on the estimates of the model, the impact of cohort size on skill prices and, conseque...

The acetylcholine receptor (AChR) from vertebrate skeletal muscle initiates voluntary movement, and its kinetics of activation are crucial for maintaining the safety margin for neuromuscular transmission. Furthermore, the kinetic mechanism of the muscle AChR serves as an archetype for understanding activation mechanisms of related receptors from the Cys-loop superfamily. Here we record currents...

In this paper we examine the effect of stochastic volatility on optimal portfolio choice in both partial and general equilibrium settings. In a partial equilibrium setting we derive an analog of the classic Samuelson–Merton optimal portfolio result and define volatility-adjusted risk aversion as the effective risk aversion of an individual investing in an asset with stochastic volatility. We ex...

Oxygen equilibrium curves and the relationships between the partial pressure of CO2 and pH were determined for the haemolymph of the arachnids Eurypelma californicum, Pandinus imperator and Cupiennius salei. A new type of experimental apparatus was constructed, tested and used to make these measurements on small undiluted cell-free haemolymph samples. Most of its components were made in our wor...

In this paper I critically analyse the view that John Hicks sought to establish, according to which Walras’ and Marshall’s approaches to price theory, while differing in scope (that is, general vs. partial analysis), are basically similar in their aims, presuppositions and results. By focusing on a special kind of economy (the pure-exchange, two-commodity economy), which has been formally studi...

Cut games and party affiliation games are well-known classes of potential games. Schaffer and Yannakakis showed that computing pure Nash equilibrium in these games is PLScomplete. In general potential games, even the problem of computing any finite approximation to a pure equilibrium is also PLS-complete. We show that for any є > 0, we design an algorithm to compute in polynomial time a (3 + є)...

The last twenty years has seen an extensive and exhausting debate on how to improve the institutions of African states. But progress has been patchy at best. Many of the problems arise from a ‘partial-reform equilibrium’; initial reforms are undertaken, but then strong resistance is encountered, and reform is not completed. Consequently, although donors may be heartened to find governments spea...
