We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium interim Pareto optimality is equivalent to intergenerational exchange e¢ciency, which in turn implies dy...

The role of the dairy cow is to help provide high-quality protein and other nutrients for humans. We must select and manage cows with the goal of reaching the greatest possible effi ciency for any given environment. We have increased effi ciency tremendously over the years, yet the variation in productive and reproductive effi ciency among animals is still quite large. In part this is because o...

In this paper I compare inter-thread communication methods: blocking queue and LMAX Disruptor without synchronization according to a number of threads (CPU cores) and consumer rate. The research is carried out using a multiprocessor machine with Non Uniformed Memory and Oracle Java Runtime Environment. I determine if processing on many multi-core CPUs with NUMA is faster than on single multicor...

During the last years, the concept of input congestion and technical ineff-ciency in data envelopment analysis (DEA), have been investigated by manyresearchers. The motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. More-over, we extend the models to estimate input congestion, technical ineciencyand output reduct...

The utilization of networked, shared, heterogeneous workstations as an inexpensive parallel computation platform is an appealing concept that has received quite a bit of attention in the literature. However, most e ciency measures for parallel computation are oriented towards the use of tightly-coupled, dedicated, homogeneous processors. We propose a new e ciency measure for parallel computatio...

This paper addresses a fundamental, yet unresolved, question: is statistical discrimination a market failure? I contrast a competitive model of statistical discrimination with the allocation chosen by a social planner who must respect the same informational and technological constraints as the rms in the decentralized model. Equilibria are always contrained ine cient due to \free riding" in hum...

—Recently it was shown that Shannon entropy is more Bahadur ef cient than any Rényi entropy of order > 1: In this paper we shall show that relative Bahadur ef ciency between any two Rényi entropies of orders 2 ]0; 1] is 1 when the relative Bahadur ef ciency is de ned according to [1]. Despite the fact that the relative Bahadur ef ciency is 1 it is shown that in a certain sense Shannon entropy i...

The thesis comprises two parts: the rst part presents channel-adaptive techniques to achieve high spectral e ciency in a single user multiple-input multiple-output (MIMO) system; the second part exhibits a programmable and recon gurable software-de ned-radio workbench (SDR-WB) in the Matlab/Octave environment that accommodates a variety of wireless applications. In an attempt to achieve high sp...
