非线性古诺模型下的供应链协调问题研究

针对市场需求与资源投入并不一定呈线性增长的特点,在完全信息静态古诺模型的基础上,当面对共同的供应商时,分析在独立市场与竞争市场下的销售商与供应商的利润函数,并在利润驱动导向的前提下,研究其市场进入决策问题。研究发现:当进入成本低于某一阈值,企业应选择进入市场,并且在竞争市场中会降低在位企业的最优定价,减少其市场份额。

增值税改革的负效应及其对策研究——以江苏省为例

在我国进行增值税改革试点的背景下,本文以江苏省的实际情况为例,分析了增值税改革对财政收入、投资和就业等方面可能产生的负效应,认为增值税改革短期内会导致财政收入减少,引发投资需求过旺,增加劳动就业的压力。文章提出,增值税转型改革应分步实施,以减轻财政压力,控制过度投资;慎重对待增值税征税范围的扩大,降低财政对增值税的依赖;规范增值税的税收优惠,积极推行配套改革,完善分税制管理体制,适当扩大地方税权;加强税收征管,缓解增值税转型的财政压力。

Understanding pastoralists’ dynamic insurance uptake decisions: Evidence from four-year panel data in Ethiopia

Despite the demonstrated benefits of index insurance, its adoption rate remains low in many developing countries. While a growing literature explores the factors associated with insurance uptake, we still know little about its dynamic patterns. Using a unique data set covering four years and six semi-annual sales periods of an index-based livestock insurance (IBLI) product in southern Ethiopia, we examine the dynamics of pastoralists’ demand for IBLI. We find that reduced insurance premiums induce households to purchase IBLI. While a one-shot subsidy can create a price reference point that may reduce the subsequent uptake, we do not find such price-anchoring effects. We also find that overall uptake decision is positively correlated intertemporally, although there is no strong evidence for learning by doing or learning from others. Finally, we show that pastoralists are more likely to purchase IBLI when drought risk is high, consistent with the existence of spatiotemporal adverse selection. We discuss the potential of distributing discount coupons to trigger initial uptake and adjusting premium rates dynamically to avoid spatiotemporal adverse selection as effective policy tools toward sustainable livestock insurance. Overall, our study signifies the importance of an empirical analysis that considers the dynamic demand structure.     

Does Money Have a Role in Monetary Policy for Price Stability under Inflation Targeting in Thailand?

This paper deploys Thai quarterly data for the study period 1999q1–2014q4 to econometrically investigate the proposition that money growth is an important, if not the sole, determinant of inflation under inflation targeting and that the money growth-inflation relation is not conditional on the stability of the money-demand function. The autoregressive distributed-lag (ARDL) bounds-testing results suggest that, across the study period, the Thai money stock (narrow or broad), real output, prices, interest rates and exchange rates maintained a long-run equilibrium relationship. The associated error-correction model of inflation confirms the cointegral relationship among money (narrow or broad), real output, prices, interest rates and exchange rates. It also suggests that money growth has a significant distributed-lag impact on inflation. The presence of this money growth-inflation relationship was associated with a stable narrow money-demand function, whereas the broad money-demand function remained unstable. These results for the study period are consistent with the view that the causal relationship between money growth and inflation holds in Thailand under inflation targeting when the Bank of Thailand deploys a short-term policy interest rate, rather than a monetary aggregate, as the instrument of monetary policy and that this relationship is not conditional on the stability of the money-demand function.
