Using quarterly call report data from 2000 to 2016, we reexamine the relationship between net interest margins (NIM) and the yield curve for more than 5,500 U.S. commercial banks. In the full sample, yield curve and RGDP growth have positive effects on NIM, while inflation and deposit‐to‐loan ratios (D/L) have negative effects. Splitting the sample around the 2007–2009 crisis, we show the impact of yield curve and RGDP growth on NIM increasing during the “recovery” (2009Q3 to 2016Q4), and inflation and D/L changing signs. Positive effects of yield curve on profits vary with bank size and change over time.  相似文献

We test whether the channel by which the government plays the role of political patron to selected firms influences analysts’ forecast precision in Malaysia. Correcting for analysts’ self-selection bias, we find a negative relation between analysts’ forecast errors and the social dimension of political patronage, as proxied by government-controlled institutional ownership. The reverse is found for the economic dimension of political patronage, as proxied by the percentage shareholding of government-linked corporations. We find no evidence that the personal dimension of political patronage influences analysts’ forecast precision.  相似文献

Organisations increasingly use websites to promote prosocial behaviour such as volunteering, philanthropy, and activism. However, these websites often fail to encourage prosocial behaviours effectively. To address the lack of relevant research, we develop, then refine, a design model that identifies the user experience factors that create intention to engage in prosocial behaviour on websites. We test an initial model developed from the literature, by interviewing forty participants, each of whom visited and compared six volunteering websites. Our analysis of the participants' user experience reveals eighteen elements that interplay to create intention to engage in prosocial behaviour. Our refined design model comprises ten website features (interaction, factual, anecdata, external recognition, organisational expression, value suggestion, explanatory content, visual media, written media and, website design), seven perceptions (ease of use, aesthetics, information quality, trust, negative affect, positive affect, and argument strength), and one motivation (egoism). These findings provide novel insights into how to design Information and Communications Technology (ICT) to encourage prosocial behaviour.  相似文献

This paper studies one‐dimensional Ornstein–Uhlenbeck (OU) processes, with the distinguishing feature that they are reflected on a single boundary (put at level 0) or two boundaries (put at levels 0 and d > 0). In the literature, they are referred to as reflected OU (ROU) and doubly reflected OU (DROU), respectively. For both cases, we explicitly determine the decay rates of the (transient) probability to reach a given extreme level. The methodology relies on sample‐path large deviations, so that we also identify the associated most likely paths. For DROU, we also consider the ‘idleness process’ Lt and the ‘loss process’ Ut, which are the minimal non‐decreasing processes, which make the OU process remain ≥ 0 and ≤ d, respectively. We derive central limit theorems (CLTs) for Ut and Lt, using techniques from stochastic integration and the martingale CLT.  相似文献

Informal Traders and the Battlegrounds of Revanchism in Cusco,Peru   总被引:2,自引:0,他引:2  
Informal trading in the global South, particularly in Latin America, is the subject of revanchist urban policy and yet few studies have examined the longer‐term impacts of such intolerant policies on traders. This article explores the evolution and impacts of revanchist policies directed at informal traders in the Andean city of Cusco. It makes two key contributions. First, it documents a shift from early revanchist policies to a post‐revanchist era where policies have become more tolerant of informal traders. However, contemporary policies fall short of a supportive environment for informal trading, hence the authors recommend changes that will ensure informal traders can access the city's streets and become an accepted part of the urban fabric. Second, given the lack of theoretical attention given to the impacts of revanchism, a battlegrounds framework is developed, consisting of spatial, political, economic and socio‐cultural battlegrounds. This framework provides a comprehensive insight into the complex set of interactions that exist between informal traders and the state. It is hoped that the framework will provide a tool for further research into the highly damaging impacts of revanchism across the globe.  相似文献

In Germany the car tax is derived from the cylinder capacity. Since 2009 the amount of carbon emissions serves as an additional criterion. Taking recent developments into account, cylinder capacity can no longer be justified as a reasonable tax basis. Instead I propose a progressive tax based solely on carbon emissions to achieve much more appropriate results.  相似文献

We investigate the importance of geo‐strategic and commercial motives for the allocation of German aid to 138 countries over the 1973–2010 period. We find that geo‐strategic and commercial motives matter. When we relate them to the political color of the German government in general, and the Ministry for Economic Cooperation and Development and the Federal Foreign Office in particular, we find their importance to be at least as strong under the socialist leadership. Socialist leadership decreases the amount of aid commitments, controlled for other factors.  相似文献
