Measurement Bias in the HICP: What do we know and What do we need to know?

Abstract. The Harmonized Index of Consumer Prices (HICP) is the primary measure of inflation in the euro area, and plays a central role in the policy deliberations of the European Central Bank (ECB). The ECB defines its Treaty mandate of price stability as '… a year‐on‐year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%[…] to be maintained over the medium term.' Among the rationales given for defining price stability as prevailing at some positive measured inflation rate is the possibility that the HICP as published incorporates measurement errors of one sort or another that may cause it to systematically overstate the true rate of inflation in the euro area. This paper reviews what currently is known about the scope of measurement error in the HICP. We conclude that given the vague conceptual framework of the HICP, the scant research on price measurement issues in the EU and the ongoing improvements in the HICP, there is very little scientific basis at this time for a point (or even an interval) estimate of a positive bias in the HICP.     

Estimating dynamic demand for airlines

This paper uses an original panel dataset with posted prices and sales to estimate a dynamic demand. We find that consumers become more price sensitive as time to departure nears which is consistent with having lower valuations. This result provides empirical support to a key theoretical implication in Deneckere and Peck (2012)—high-valuation consumers purchase earlier. We also find that the number of active consumers increases closer to departure.     

Semi-parametric estimation of American option prices

We introduce a novel semi-parametric estimator of American option prices in discrete time. The specification is based on a parameterized stochastic discount factor and is nonparametric w.r.t. the historical dynamics of the Markovian state variables. The historical transition density estimator minimizes a distance built on the Kullback–Leibler divergence from a kernel transition density, subject to the no-arbitrage restrictions for a non-defaultable bond, the underlying asset and some American option prices. We use dynamic programming to make explicit the nonlinear restrictions on the Euclidean and functional parameters coming from option data. We study asymptotic and finite sample properties of the estimators.     

Valuation structure in first-price and least-revenue auctions: an experimental investigation

In many auctions the valuation structure involves both private and common value elements. Existing experimental evidence (e.g. Goeree and Offerman in Am. Econ. Rev. 92(3):625–643, 2002) demonstrates that first-price auctions with this valuation structure tend to be inefficient, and inexperienced subjects tend to bid above the break-even bidding threshold. In this paper, we compare first-price auctions with an alternative auction mechanism: the least-revenue auction. This auction mechanism shifts the risk regarding the common value of the good to the auctioneer. Such a shift is desirable when ex post negative payoffs for the winning bidder results in unfulfilled contracts, as is often the case in infrastructure concessions contracts. We directly compare these two auction formats within two valuation structures: (1) pure common value and (2) common value with a private cost. We find that, relative to first-price auctions, bidding above the break-even bidding threshold is significantly less prevalent in least-revenue auctions regardless of valuation structure. As a result, revenue in first-price auctions is higher than in least-revenue auctions, contrary to theory. Further, when there are private and common value components, least-revenue auctions are significantly more efficient than first-price auctions.     

滇中城市群优化发展模式研究

本文以滇中城市群规划为例,结合中外合作编制《云南省滇中城市群规划》实践,采用多情景发展模拟,将GIS工具与传统规划手段紧密耦合,针对离散型、区域型、都市型、网络型四种发展模式进行情景分析,并从中探索适合滇中城市群未来发展的、相对合理的规划方案。最终得出一个阶段性发展方案,即在2030年以前滇中城市群以区域型模式为主导,2030年以后以网络型模式为主的发展模式,推进滇中地区稳步、有序发展,逐步实现生态安全、资源集约、经济繁荣三者高度统一。     

Exploring the Relationship between Sustainability Reporting and Sustainability Management Practices

There has been a dramatic uptake of sustainability reporting (SR) and sustainability management practices over the last two decades, in turn raising questions about the relationship between external disclosure and internal practice of corporate sustainability. Previous literature has emphasized the role of external pressures in driving SR adoption. However, as recent practitioner surveys also identify the existence of internal motives for SR, a more comprehensive analysis of this relationship is needed. In order to address this issue, we develop a framework accounting for four company‐level SR configurations, resulting from different levels of importance of external and internal motives for SR. Then, four exploratory cases serve to illustrate these configurations and to describe the respective roles of SR at the company level. As considerable diversity among these SR practices is found, our findings point to the relevance of both external and internal motives in understanding SR contribution to corporate sustainability.

Bank presence in firm equity: A diversification based approach

This study analyses the possible reasons for banks deciding to invest in firm equity, based on the fundamentals of the strategic diversification literature. Those fundamentals suggest that it may be in response to the negative evolution of other aspects of banking business, namely, credit business, fixed interest business and services, as well as the bank's level of efficiency. The results confirm the hypotheses that the decision to hold equity in other firms is related to the evolution of the bank's other businesses. However, the results for savings banks differed from those for banks.
