We present a hierarchical architecture based on recurrent neural networks for predicting disaggregated inflation components of the Consumer Price Index (CPI). While the majority of existing research is focused on predicting headline inflation, many economic and financial institutions are interested in its partial disaggregated components. To this end, we developed the novel Hierarchical Recurrent Neural Network (HRNN) model, which utilizes information from higher levels in the CPI hierarchy to improve predictions at the more volatile lower levels. Based on a large dataset from the US CPI-U index, our evaluations indicate that the HRNN model significantly outperforms a vast array of well-known inflation prediction baselines. Our methodology and results provide additional forecasting measures and possibilities to policy and market makers on sectoral and component-specific price changes. 相似文献

The term premium has become increasingly important in discussions of monetary policy formulation. This paper reviews two approaches to embedding a variable term premium into an otherwise standard modern DSGE model. The first approach maintains frictionless asset trade but alters preferences so that agents are more averse to the risk in long bonds. The second approach uses traditional preferences, but segments asset trade between long and short bonds. Policy issues are also discussed. 相似文献

Sovereigns mainly issue inflation-linked bonds (ILB) in order to save money. More than 15 years’ experience with this financial instrument in the United States has led to the conclusion that these bonds are characterized by low liquidity issues. Recently, various papers have started to analyze the impact of liquidity on ILB yields. This paper develops a new strategy for estimating the liquidity premium based on Campbell and Shiller's (1996) hypothetical ILB yields. We find significant effects of ILB-specific liquidity measures for the United States, the United Kingdom and Canada. Based on these findings, we derive the liquidity premium in ILB yields, liquidity-adjusted estimates for the break-even inflation rate and the inflation risk premium. In the United States, for instance, the average of the liquidity premium is 0.56%-points, and the average liquidity-adjusted break-even inflation rate and inflation risk premium amount to 2.67%-points and 0.22%-points, respectively. 相似文献

The Sydney housing market peaked in 2003. The period 2001–2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in broad agreement regarding the timing of the turning point in the housing market, some important differences also emerge. In particular, we find evidence of sample selection bias in our hedonic and repeat-sales data sets (with the former focusing more on better quality dwellings and the latter more on lower quality dwellings). These sample selection biases could in turn cause bias (in opposite directions) in our hedonic and repeat-sales indexes. Median indexes may likewise be biased as a result of an apparent decline in the average quality of dwellings sold in the latter part of the sample. We also find evidence of convergence in prices across regions during the boom and divergence in the subsequent bust. 相似文献

股票市场中股票价格的波动是相互影响的,但不同的股票其价格波动时对其他股票价格行为的影响能力是不同的。本文通过对我国上海A股市场的实证分析表明,有少数股票其价格波动时对其他股票价格行为有很强的影响能力,而大多数股票的这种影响能力很小。此外,单个股票价格波动时引起其他股票价格涨、跌的能力一般都有显著差异。 相似文献

This paper decomposes the break-even inflation rates derived from inflation-indexed bonds into inflation risk premia, liquidity risk premia, and inflation expectations. I estimate a common factor model with autoregressive conditionally heteroscedastic (ARCH) errors that extracts co-movements from twenty-two monthly and quarterly indicators to identify these three components. The results indicate that the sharp declines in the 10-year and 5-year break-even inflation rates in 2009 reflect a substantial increase in liquidity risk rather than a decrease in inflation expectations. Break-even inflation rates underestimate inflation expectations over nearly the entire sample due to the liquidity risk premia carried by the inflation indexed bond yields. Also, the model-implied inflation expectations show better forecast performance for the average annual inflation rates than raw break-even inflation rates, the Survey of Professional Forecasters, and the Surveys of Consumers inflation forecasts. 相似文献

财政分权、政府竞争与土地价格结构性偏离 总被引:3,自引:0,他引:3
财政分权背景下地方政府的财政约束和政府竞争是导致土地价格结构性偏离的根本原因。地方政府存在拉升商业用地和居住用地出让价格的倾向,金融宽松环境和投机行为盛行会使这两种土地出让价格存在正向偏离其理论地价的可能;而地方政府对流动性税基的争夺过程会导致工业用地出让价格低于其理论价格。工业用地价格与商业和居住用地价格正是在政府这两种反作用力量的作用下出现结构性偏离。 相似文献

运用CAPM理论中的边际风险价格的概念,通过分析一个包含了黄金市场和股票市场在内的市场资产组合,定量给出了黄金的风险溢价。同时检验了黄金收益是否在CAPM框架内有效。在与我国股市进行比较之后,得出投资者可将黄金包括到投资组合中去,以取得更好的风险收益比。 相似文献

We analyze history-based price discrimination in an asymmetric industry, where an incumbent, protected by switching costs, faces an entrant who does not have access to information about consumers’ purchase histories. We demonstrate that consumer surplus is higher with uniform pricing than with history-based price discrimination. We find that the entry decision is invariant to whether the incumbent implements history-based pricing or uniform pricing. This implies that the potential abuse of market dominance imposed by history-based price discrimination is exploitation, not exclusion. Finally, we establish that the profit gain to the incumbent from history-based pricing exceeds the associated loss to consumers. 相似文献
