Long-term persistence in corporate capital structure: Evidence from India

This study examines the stability of corporate capital structure in a sample of listed Indian firms for the period 1988–2015. In general, the firms do not maintain a stable level of leverage over long durations. The firm specific temporal variations in leverage are large and significant. We find that capital structure models that incorporate time varying firm effects perform better in explaining the variation in leverage than those that employ time invariant firm effects. The cross-sectional distribution of leverage also exhibits considerable variations over time. The quartile decompositions of leverage cross-sections reveal that migrations across leverage quartiles are pervasive. Only the firms with low leverage ratios ratio exhibit some persistence in their leverage ratios. High leverage ratios are not rare but are invariably transient.     

新会计准则实施后营业利润的信息质量研究

以新会计准则实施对营业利润信息质量的影响为研究对象,利用2001～2010年A股上市公司数据,从会计信息的持续性、稳健性和相关性三个方面综合评价新会计准则实施对营业利润信息质量的影响,同时分析了资产减值损失、公允价值变动收益和投资收益的并入对营业利润信息质量的影响。实证结果显示新准则对营业利润的综合影响结果是价值相关性提高,但持续性和稳健性下降。     

The potential harms of goodwill impairment avoidance: Evidence based on future performance and stock prices

The rapidly increasing volume of goodwill assets in the capital market generates potential risks due to the possibility of an untimely recognition of goodwill impairment. In this paper, we investigate the financial consequences of goodwill impairment avoidance based on firms’ future performance and stock prices. Using Chinese A-share listed firms with goodwill balances, we find that avoiding goodwill impairments negatively affects a firm’s performance growth and increases its risk of a future stock price crash. These adverse effects continue for the three years following the goodwill impairment avoidance. Our results indicate that goodwill impairment avoidance has detrimental impacts on a firm’s future performance and stock price and that these impacts are persistent. Our conclusions are helpful for regulators on how to prevent the risks hidden in goodwill impairment recognition and maintain the stable development of the financial market.     

通货膨胀的惯性特征及其货币政策启示

通货膨胀惯性是指通货膨胀在受到随机扰动因素冲击后偏离其长期均衡水平的趋势会持续很久,通常用通胀自回归模型中滞后项系数之和来度量。混合的新凯恩斯主义菲利普斯曲线令人信服地解释了通货膨胀惯性的微观基础,即价格粘性和经济参与人的后视行为。高通货膨胀惯性会削弱货币政策调控的效果,提高中央银行反通胀的社会成本。中央银行承诺在较长时期内钉住一个稳定的名义锚(例如明确或隐性的通货膨胀目标制)则是降低通货膨胀惯性的有效途径。     

Economic policy uncertainty: Persistence and cross-country linkages

This paper provides new evidence on the stochastic behaviour of the EPU (Economic Policy Uncertainty (EPU) index constructed by Baker et al. (2016) in six of the biggest economies (Canada, France, Japan, US, Ireland, and Sweden), and also on cross-country linkages, over the period from January 1985 to October 2019. For this purpose, it uses fractional integration/cointegration methods to measure the degree of persistence of the EPU and whether there exists a long-run equilibrium relationship linking the individual indices. This framework is much more general than the standard approaches based on the I(0)/I(1) dichotomy since it allows for fractional values of the integration/cointegration parameter and therefore does not impose restrictive assumptions on the dynamic behaviour of the individual series and their linkages. EPU is found to be in most cases a non-stationary, mean-reverting series which is characterised by long memory. Several breaks are also detected in each country. Finally, there is very little evidence of cross-country linkages. Our analysis provides fresh insights into the degree of persistence and the transmission of EPU shocks and has implications both for investors having to make risk management decisions and choose investment strategies and policymakers having to design effective macroeconomic policies.     

Tourism in Iceland: Persistence and seasonality

This paper analyses tourism in Iceland using fractional integration and taking into account the seasonality and the degree of persistence in the data. Using annual data, the unit root hypothesis cannot be rejected, implying permanency of shocks. However using, monthly data, a break is found at 2009m7 and the orders of integration are in the interval (0, 0,5) suggesting mean reversion. The conclusion is that exogenous shocks impacting inbound tourism do not persist and tend to disappear relatively fast. The key policy implications thereof are reported at the end of the paper, critiquing the classical response to perceived slumps in inbound tourism that include marketing and promotion instead of developing infrastructure in anticipation of resumed growth in inbound tourism.     

Expectations as a source of macroeconomic persistence: Evidence from survey expectations in a dynamic macro model

Embedding survey expectations in a standard DSGE model helps to identify key slope parameters in standard relationships; dramatically reduces the need for lagged dependent variables, often motivated by price-indexation and habit formation; and obviates the need for autocorrelated structural shocks in the key equations. Formal statistical tests demonstrate that much of the persistence in aggregate data is better accounted for by slow-moving expectations, rather than by habits, indexation and autocorrelated structural shocks.     

Entrepreneurial profitability and persistence: Chile versus the U.S.A.

This article empirically evaluates the main determinants of business performance, focusing on the emergence and sustainability of profits for an emerging economy such as Chile. Furthermore, the paper compares the results obtained with Chilean data to those for the U.S.A. This comparison is interesting because of the recent emergence of some literature that relates geographic location to performance. The results show that the industry effect is more important in Chile than in the U.S.A., that the persistence of rents in Chile is explained more evenly for reasons associated to business-, industry- and corporate-specific effects, and that the path to lower rents is more difficult to revert in Chile than in the U.S.A.     

Technical trading revisited: False discoveries,persistence tests,and transaction costs

We revisit the apparent historical success of technical trading rules on daily prices of the Dow Jones Industrial Average index from 1897 to 2011, and we use the false discovery rate (FDR) as a new approach to data snooping. The advantage of the FDR over existing methods is that it selects more outperforming rules, which allows diversifying against model uncertainty. Persistence tests show that, even with the more powerful FDR technique, an investor would never have been able to select ex ante the future best-performing rules. Moreover, even in-sample, the performance is completely offset by the introduction of low transaction costs. Overall, our results seriously call into question the economic value of technical trading rules that has been reported for early periods.
