SIDD: An adaptable framework for analysing the distributional implications of policy alternatives where savings and employment decisions matter

The Simulator of Individual Dynamic Decisions, SIDD, is publicly available software for analysing the distributional effects of policy alternatives. SIDD is a framework, rather than a model, in the sense that it is designed to facilitate adaptation to alternative country and policy contexts. The microsimulation framework can generate panel data describing a wide range of characteristics at annual intervals for each adult in an evolving population cross-section. Structural methods are employed to project savings and employment decisions, making SIDD a suitable tool for exploring the incentive effects of policy alternatives, and how these vary across the population and over time. The framework is also a valuable test-bed for empirical analyses of alternative behavioural assumptions, especially those concerning preferences for risk. In an effort to support good policy design and empirical analysis of savings and labour supply behaviour, SIDD has been made free for download from www.simdynamics.org.     

Private consumption behaviour, liquidity constraints and financial deregulation in France: a nonlinear analysis

This paper examines the effect of financial deregulation on consumption expenditure in France during the period 1970–1993. A nonlinear model for consumption which allows for liquidity constraints through a time-varying parameter dependent on a proxy for financial deregulation is estimated using nonlinear instrumental variables. It is concluded that in France financial deregulation has significantly reduced liquidity constraints faced by consumers, allowing a higher percentage of the population to smooth consumption over time. Evidence is also provided that the intertemporal elasticity of substitution is not significantly different from zero at conventional nominal levels of significance.

Decreasing Impatience: A Criterion for Non‐stationary Time Preference and "Hyperbolic" Discounting

Despite recent interest in hyperbolic discounting, there has been little discussion of exactly what property of time preferences is instantiated by hyperbolic or quasi‐hyperbolic functional forms. The paper revives an earlier proposal in Prelec (1989) that the key property is Pratt–Arrow convexity of the log of the discount function, which corresponds to decreasing impatience(DI) at the level of preferences. DI provides a natural criterion for assessing the severity of departure from stationarity in that greater DI is equivalent to more choices of dominated options in two‐stage decision problems, as well as greater convexity of the log of the discount function. Inefficient choices may arise as intentional precommitments, or as unintended reversals of preference by “naïve” agents.     

要素价格与中国制造业出口技术结构——基于省级动态面板数据的系统GMM估计

文章基于2002-2008年省级面板数据,运用系统广义矩(System GMM)估计法从国家和地区两个层面就劳动力、资本和原材料等要素价格上涨对制造业出口技术结构的影响进行了实证检验。研究结果表明,要素价格上涨在国家层面上对出口技术结构表现出显著的"倒逼"效应,即要素价格上涨有利于我国对外贸易增长方式的转变,但要素价格上涨对我国东、中、西部地区出口技术结构升级的影响不同。从动态视角看,要素价格上涨所体现出的"倒逼"效应越来越小,而其表现出来的"倒退"效应越来越明显,即要素价格上涨越来越成为企业本身发展的成本负担。     

基于随机贴现因子的人民币与新台币汇率定价

基于随机贴现因子定价理论,采用无套利定价法,推导出人民币与新台币的即期汇率与随机贴现因子、远期汇率之间的关系,并利用人民币和新台币的无本金交割远期外汇作为远期汇率,对人民币与新台币的即期汇率进行定价。实证研究结果显示,人民币与新台币的汇率主要受中国大陆地区和台湾地区的股票市场和债券市场波动的影响。用本文模型定价模拟的即期汇率与真实汇率的变动趋势较为一致,这表明本文模型可为人民币与新台币之间的双向直接兑换提供依据,进而有助于建立两岸货币清算机制。     

收入不平等对经济增长的倒U型影响:理论和实证

文章致力于从理论和实证两个维度,探讨收入不平等对长期经济增长"先促进后阻碍"的"倒U型"影响.文章首先基于一个拉姆齐模型,从理论上证明这一"倒U型"关系的存在;其次是构建实证模型,根据跨国横截面数据,分别运用OLS和GMM估计方法从实证的角度检验这一"倒U型"关系的存在.实证结果显示:GMM估计方法要优于OLS估计方法,在其他条件不变情况下,收入不平等有一个合理区间,如果以基尼系数衡量不平等程度,这一数值处于0.37-0.40之间.当一国初始收入不平等程度低于最优值时,可以通过提高收入不平等程度来加快经济增长的速度;反之,则应通过降低收入不平等程度来促进经济的增长.     

Empirical and public choice evidence for hyperbolic social discount rates and the implications for intergenerational discounting

The derivation of the correct discount rate for intergenerational projects in Cost Benefit Analysis is particularly contentious. Public choice has resulted in lower discretionary exponential discount rates for many intergenerational projects in Britain and the USA. This is shown to be strong indirect evidence that the true social discount rate may be a hyperbolic (rather than an exponential) function. There is also empirical evidence for this hypothesis. The hyperbolic nature of discounting is also a standard finding in the behavioural sciences. For intergenerational time frames hyperbolic discount rates should be employed together with exponential discount rates in cost-benefit sensitivity analyses.Sincere thanks to Maureen Cropper and Paul Portney for supplying their survey results and to Elaine Barrow and Phillip Judge for graphics assistance.

Keynes's theory of liquidity preference and his debt management and monetary policies

This paper seeks to bolster the view that Keynes was a monetaryeconomist concerned primarily with monetary and not fiscal policy.His most fundamental policy conclusion for national economieswas that the authorities could control the long-term rate ofinterest and should do so to promote investment, growth andemployment. Keynes's theory of liquidity preference is presentedas a theory of money as a store of value that leads to thisfundamental policy conclusion. The theory is then applied toexplain the debt management, monetary and international financialpolicies that were adopted in World War II.

Modelling dynamic storage function in commodity markets: Theory and evidence

In this work, we derive a model to investigate the optimal storage policy in metal commodity markets. From an inter-temporal setting, we carry out a criterion driving the stockholding decisions based on Tobin's q rule in which marginal benefits from holding inventories can be compared with marginal storage costs.We estimate the model for the world copper market by taking into account both spot price and convenience yield equations. In our sample, the estimated models are statistically robust and economically coherent with the theory, even though the patterns of the inventory accumulation process show high sensitivity to the uncertainty about worldwide economic conditions.     

Insights on endogenous money and the liquidity preference theory of interest

It is argued that the debate between “structuralist” and “horizontalist” has long been obscured because of inadequate treatment, in both approaches, of the credit-money supply and of the total money supply. As a result, endogenous money models still have serious limitations today. On the one hand, the bank loan markup and the loan interest rate are exogenous in the horizontalist model, which supposes that they do not depend on the money/liquidity market conditions (as if bank loans did not compete with the existing liquidity). On the other hand, although interest rates are endogenous in the structuralist model, they result from inappropriate treatment of the loan supply and money/liquidity supply. This article aims to remove these shortcomings. It offers a theoretical framework and formal modeling where the creditworthy demand for loans determines the bank loan supply, given the central bank refinancing interest rate, while the total supply and demand for liquidity-money determines the markup and the market rate of interest in accordance with Keynes’s liquidity preference theory. In this framework, the post Keynesian theory of endogenous money and Keynes’s “verticalist” view prove to be analytically complementary.     

Time Inconsistency and the Exchange Rate Channel of Monetary Policy

This paper analyses time–inconsistency problems related to the exchange rate channel of monetary policy. Within a simple open–economy macroeconomic model, where the exchange rate is the only forward–looking variable, we show that a difference emerges between optimal policy under discretion and under commitment. Moreover, the nature of the time–inconsistency problem resembles that resulting from standard New Keynesian models: when cost–push shocks occur, the exchange rate channel gives rise to excessive output stabilisation and insufficient inertia in monetary policy under a discretionary policy.

On the Choice Between the Stocking Rate and Time in Range Management

A long standing question in range management concerns the relative importance of the stocking rate versus the length oftime during which animals graze a particular rangeland. Weaddress this question by analyzing the problem faced by a privaterancher who wishes to minimize the long run expected net unit cost (LRENC) from range operations by choosing either the stocking rate or the length of time during which his animals graze hisrangeland. We construct a renewal-theoretic model and show that,in general, this rancher's LRENC with an optimally chosen stocking rate is lower than his LRENC with an optimally chosen grazing cycle length. From a management perspective, this means that correct stocking of the range is more important than the length of time during which animals graze the range. In addition, our research shows how to address questions concerning the desirability of temporal versus non-temporal controls in managing naturalresources such as fisheries and hunting grounds.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

Nonlinearities in the real exchange rates: new evidence from developed and developing countries

This paper investigates nonlinearities in the dynamics of real exchange rates. We use Monte Carlo simulations to establish the size properties of the Teräsvirta-Anderson test, when the dynamics of the real exchange rate is influenced by an exogenous process. In addition, we show that a modified nonlinearity test, which includes additional right-hand-side variables, performs much better than the original in both Monte Carlo exercises and in the actual data on 1431 bilateral real exchange rate series. Finally, we investigate the dynamics of the real exchange rate for both developed and developing countries using the modified test for the recent floating period. In general, the results find a greater incidence of nonlinear dynamics for developing country real exchange rates.     

Time series analysis of economic growth rate series in Nigeria: structural breaks,non-linearities and reasons behind the recent recession

This article deals with the modelling of growth rate time series in Nigeria with a view of detecting its statistical properties, structural breaks and non-linearities. We employ both fractional integration and structural break time series techniques in modelling the annual growth rate series of the Nigerian GDP growth rate for about 55 years. The data span between 1960 and 2017. The results show that Nigerian growth rate is unstable with non-linearities and long-range dependence structures. We also investigate what might explain these features and conclude that erratic political institutions, associated with poor economic management and insecurity in Nigeria, among others, in the decades after independence are the root causes of non-linearities observed, which have also led to the subsequent recent economic recession in Nigeria.     

The inflationary bias of real uncertainty and the harmonic Fisher equation

Summary. We argue that real uncertainty itself causes long-run nominal inflation. Consider an infinite horizon cash-in-advance economy with a representative agent and real uncertainty, modeled by independent, identically distributed endowments. Suppose the central bank fixes the nominal rate of interest. We show that the equilibrium long-run rate of inflation is strictly higher, on almost every path of endowment realizations, than it would be if the endowments were constant.Indeed, we present an explicit formula for the long-run rate of inflation, based on the famous Fisher equation. The Fisher equation says the short-run rate of inflation should equal the nominal rate of interest less the real rate of interest. The long-run Fisher equation for our stochastic economy is similar, but with the rate of inflation replaced by the harmonic mean of the growth rate of money.Received: 25 February 2005, Revised: 26 May 2005, JEL Classification Numbers: C7, C73, D81, E41, E58.An earlier version of this paper “Inflationary Bias in a Simple Stochastic Economy,” as a 2001 Cowles Foundation Discussion Paper No. 1333.

Exploring radio frequency identification technology's application in international distribution centers and adoption rate forecasting

Radio Frequency Identification Technology's (RFID) application in the global supply chain has seen increased attention, and international distribution centers (IDC) are now playing a more crucial role in the global supply chain operation. This paper adopts structure equation modeling (SEM) to investigate the impact of three factors mainly based on the technology acceptance model (TAM): perceived usefulness, perceived ease of use, and the social norm on the use intention of an IDC. Empirical results indicate that a revised TAM could explain the RFID acceptance behavior. Perceived ease of use, perceived usefulness, and the social norm are demonstrated to have an effect on RFID acceptance intention. The choice of RFID adoption is also impacted by the supply chain's stakeholders. Factors that affect the adoption intention of an IDC thus include customers and partners' request, government policy, and competitors that have already adopted RFID. Furthermore, the study adopts the binary Logit model based on the stated preference method's data to predict the possible adoption rate of the RFID system in the adoption intention of an IDC. This empirical study shows that significant statistical determinants influencing RFID acceptance are: system purchasing fixed cost, variable cost, and perceived usefulness. Our model also predicts that the penetration of RFID application in Taiwan's international distribution centers could hit the 25% adoption rate. The study provides several managerial implications and suggests future research directions.
