We analyse the optimal location choice of a monopolistic firm that operates two arbitrarily located platforms on a two‐sided market. By extending the traditional Hotelling framework, we show that the optimal platform locations are equivalent to the one‐sided benchmark if both sides are either restricted to single‐ or multi‐homing. In the mixed case (one side single‐homes, the other one multi‐homes), the optimal platform locations are in line with the respective symmetric case. If the monopolist is restricted to choosing the same location on either side of the market, the optimal locations are determined by the relative profitability of the market sides. 相似文献

I provide a brief discussion of the Handelsblatt ranking by focusing on its journal quality weights. I summarize the methodology underlying journals’ prestige measure, which is derived from their citation networks, and discuss its strengths and shortcomings. Although I agree that Handelsblatt ranking provides a great service to the profession, that same profession needs to be rather careful not to overemphasize the journal quality weights. 相似文献

This paper presents a model to explain the official discount rate of the Central Bank of Austria–Hungary from 1876 to 1913.
The discount rate is assumed to depend on the liquidity ratio of the Bank, defined as the ratio of its stock of metals to
banknotes issued, and on changes in foreign discount rates. The paper also presents an equation explaining the liquidity ratio.
We use “not equally spaced chronologically ordered data” referring to the 50 discount rate changes enacted. The regressions
confirm that the liquidity ratio was the main determinant of the discount rate and that Germany (and not Great Britain) played
a significant role in determining the Austro–Hungarian discount rate and the liquidity ratios, supporting the view that the
classical gold standard was a decentralized multipolar system rather than a system fully dominated by London as suggested
by Keynes. The regressions also suggest that, although Austria–Hungary had an inconvertible paper currency (1879–1892) and
fluctuating exchange rates (1876–1895) and formally joined the gold standard only in 1902, it “shadowed” the behaviour of
gold standard Central Banks with such consistency that the stability of the estimated regressions was relatively unaffected
by the frequent institutional changes.

This paper deals with an alternative approach to treating seasonality in error correction models for consumption with a parsimonious
parameterization as proposed by Harvey and Scott. We introduce an unobserved seasonal component into an error correction model
for Austrian consumer expenditures on nondurables and services and compare the results with different approaches. The use
of stochastic seasonal results in a definite improvement of the estimated model.

The foundational international business (IB) scholarship grappled with whether multinational enterprises (MNEs) are largely efficiency‐enhancing or market‐power inducing institutions. Contemporary scholarship, however, often associates foreign direct investment (FDI) with efficiency‐enhancing properties and thus neglects the market‐power interpretation of the MNE. Such an imbalance is problematic given that the theoretical and empirical justifications behind the field's embrace of the efficiency interpretation are not fully evident. Instead, both efficiency and market‐power effects are seemingly present in cross‐border investment activity. Based on a comprehensive sample of up to 4,361 cross‐border investments materializing between 1986 and 2010, we present theoretically‐grounded hypotheses with regard to when market‐power effects will tend to dominate efficiency effects. We find that cross‐border investments undertaken by emerging‐market MNEs in both developed and emerging markets tend to involve substantial efficiency effects and minimal market‐power effects when compared with the cross‐border investments undertaken by developed‐country MNEs in both developed and emerging markets. 相似文献

Past forecast errors are employed frequently in the estimation of the unconditional forecast uncertainty, and several institutions have increased their forecast horizons in recent times. This work addresses the question of how forecast-error-based estimation can be performed if there are very few errors available for the new forecast horizons. It extends the results of Knüppel (2014) in order to relax the condition on the data structure that is required for the SUR estimator to be independent of unknown quantities. It turns out that the SUR estimator of the forecast uncertainty, which estimates the forecast uncertainty for all horizons jointly, tends to deliver large efficiency gains relative to the OLS estimator (i.e., the sample mean of the squared forecast errors for each individual horizon) in the case of increased forecast horizons. The SUR estimator is applied to the forecast errors of the Bank of England, the US Survey of Professional Forecasters, and the FOMC. 相似文献

The predictive likelihood is useful for ranking models in forecast comparison exercises using Bayesian inference. We discuss how it can be estimated, by means of marzginalization, for any subset of the observables in linear Gaussian state‐space models. We compare macroeconomic density forecasts for the euro area of a DSGE model to those of a DSGE‐VAR, a BVAR and a multivariate random walk over 1999:Q1–2011:Q4. While the BVAR generally provides superior forecasts, its performance deteriorates substantially with the onset of the Great Recession. This is particularly notable for longer‐horizon real GDP forecasts, where the DSGE and DSGE‐VAR models perform better. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

We study the rationale for an incumbent to launch a second brand when facing potential entry into a market with quality‐differentiated products and a fringe producer. Depending on market size, the cost of a second brand and a potential entrant's setup cost the incumbent might use a second brand both when deterring and when accommodating entry. For low costs of brand proliferation, the high‐quality firm will prevent entry with limit qualities or multiple brands. The high‐quality incumbent will accommodate entry only if it cannot be prevented. Accommodation is always accompanied by an additional brand safeguarding the premium brand. 相似文献

城市土地空间结构演变及其驱动机制分析 总被引:11,自引:0,他引:11
城市土地利用空间结构及其演变一直是城市地理学、城市经济学、城市规划学、土地利用学等学科研究的核心与热点问题.当前我国城市土地利用正处在快速城市化的开端,在未来近半个多世纪的时期中,将一直处于急剧突变进程之中.加强对我国城市土地空间结构演变及其驱动机制的研究,有助于我们从城市用地结构演变的根源分析问题.本文简要概括了城市土地利用空间结构的相关研究,分析了城市用地空间结构演变在空间上的两种表现形式,并在此基础上分析了城市用地空间结构演变的动力主体、驱动力和驱动机制,以期为更好地促进城市土地利用结构的优化提供相应的参考. 相似文献
