Regime-shifts and post-float inflation dynamics of Australia

Australia's inflation rate and inflation uncertainty during the post-float era 1983Q3-2006Q4 have acted as important barometers of Australia's macroeconomic performance. The conceptualization and measurement of the nexus between inflation and inflation uncertainty is subject to complex dynamics. We use the Markov regime switching heteroscedasticity (MRSH) model to capture long-run stochastic trend and short-run noisy components. This allows us to conclude that in post-float Australia the results deviate significantly from the mainstream Friedman paradigm on inflation and its uncertainty. We also critically review the plausibility of rival paradigms e.g. Keynesian-Mundell-Fleming, Friedman-Ball, Cukierman-Meltzer and Holland, explaining this paradoxical behavior. The analyses presented here provide valuable insights to policymakers grappling with the challenge of designing monetary policy to combat the adverse effects of inflation and inflation uncertainty for Australia emerging out of the global financial crisis.     

新见李塨的一篇重要佚文

《五公山人王先生行略》为新见李塨的一篇佚文,作于康熙二十七年（1688）,《恕谷后集》未收。佚文为明末清初北学派学者王余佑的传记,篇幅较长,其中不少细节为其他文献所不道,对于了解北学派的师承关系以及明末清初遗民社会生活具有重要学术价值。     

关于马克思《数学手稿》的再认识

马克思关于求导数的运算结果应该是严格的0／0的观点是正确的，因为微积分运算不同于初等数学的运算。唯物辩证法认为一切真理都是相对真理，所以不应该把初等数学中的不允许0／0的规定绝对化。但是它应该只是一个突破口，我们应该运用唯物辩证法重新建立微积分的基础。

Satisficing behavior, Brouwer’s Fixed Point Theorem and Nash Equilibrium

Summary. We show that Nash Equilibrium points can be obtained by using response maps or reply functions that simply use better responses rather than best responses. We demonstrate the existence of a Nash Equilibrium as the fixed point of a better response map and since the better response map is continuous the fixed point can be established by simply using Brouwers fixed point theorem. The proof applies to games with a finite number of strategies as well as to games with a continuum of strategies. In case the games have a continuum of strategies the payoff functions have to be continuous on the action sets and quasi concave on the players action set.Received: 22 September 2003, Revised: 31 March 2004, JEL Classification Numbers: C72, D00, D40.

On the Mechanics of Economic Convergence

Abstract. The speed at which an economy converges to its steady state is investigated by using a general non-scale R&D-based growth model. To accomplish this task, an analytical decomposition formula for the instantaneous rate of convergence is developed. By applying this decomposition to the model under study, the driving forces behind the convergence process are identified. Two convergence mechanisms are distinguished: the accumulation–decumulation mechanism and the resource–reallocation mechanism. The relative importance of the different convergence mechanisms is assessed using numerical techniques. Moreover, it is shown that the specific shock being considered might be crucial for the instantaneous rate of convergence.     

考虑延迟交货的C2M订单接受决策

The Economic Convergence Performance of Central and Eastern European Countries

A critical discussion of a comparative growth analysis about Central and Eastern European (CEE) countries is performed. The main conclusion is that there was economic convergence for most CEE accession candidates, but not between them and Western Europe. Results do justify a separation into first and second-wave accession countries, but also undermine differences in Central and Eastern Europe between accession and non-accession countries.This paper critically examines theories and empirical studies for three types of convergence, namely , and club convergence. Each can be in absolute terms or conditional to the long-term equilibrium (steady state) for each country.Empirical results are provided for all types of convergence from 1996 to 2000, both with population-weighted and non-weighted data. The analysis is performed for differently framed country subgroups considering even Western Europe for better comparability. Once absolute convergence is found through a unit root test about a standard deviation time series of cross-sectional income per capita, the regression coefficient for initial income per capita with the average growth over the sample period as dependent variable ( convergence) establishes the speed of this process. The same method applies to the conditional version by using the distance of the income from the corresponding steady state instead of the level of GDP. Then Markov chain probability matrixes (club convergence) provide information about the past behaviour of the whole cross-sectional income distribution over time, but also about intra-mobility of single countries.
