We introduce simple nonparametric density estimators that generalize the classical histogram and frequency polygon. The new estimators are expressed as linear combination of density functions that are piecewise polynomials, where the coe cients are optimally chosen in order to minimize the integrated square error of the estimator. We establish the asymptotic behaviour of the proposed estimators...
This paper proposes a new unit root test in the context of a random autoregressive coefficient panel data model, in which the null of a unit root corresponds to the joint restriction that the autoregressive coefficient has unit mean and zero variance. The asymptotic distribution of the test statistic is derived and simulation results are provided to suggest that it performs very well in small s...
A Simple Method to Visualize Results in Nonlinear Regression Models A simple graphical approach to presenting results from nonlinear regression models is described. In the face of multiple covariates, ‘partial mean’ plots may be unattractive. The approach here is portable to a variety of settings and can be tailored to the specific application at hand. A simple four variable nonparametric regre...
abstract: decentralization is a process in which local affairs are administrated by local authorities outside of activities of the central government. today, decentralization policy is considered as one of the ways that most countries adopted to improve public sector performance. in this paper using geometric analysis, innovation that this paper represents, an econometric model is considered to...
A multiperiod model is developed to measure the costs posed to the guaranty fund in a setting that incorporates risk-based capital regulations, interest rate risk and the possibility of catastrophic losses. The guaranty contract is modeled as a put option on the asset of the insurance company with a stochastic strike price and an uncertain maturity. The impacts of the key factors of this model ...
We investigate how borrowers’ corporate governance influences bank loan contracting terms in emerging markets and how this relation varies across countries with different country-level governance. We find that borrowers with stronger corporate governance obtain favorable contracting terms with respect to loan amount, maturity, collateral requirements, and spread. Firm-level and country-level co...
We investigate reactions to sunspots in a bank-run game in a controlled laboratory environment. The sunspot variable is a series of random public announcements predicting withdrawal outcomes. The treatment variable is the coordination parameter, defined as the minimum fraction of depositors required to wait so that waiting entails a higher payoff than withdrawing. We conduct treatments with hig...
Following the 1900 congress in Paris, the beginning of the 20th century saw comparative law emerge as a significant discipline. This paper suggests that the early 21st century is seeing the decline, or maybe even the ‘end’, of comparative law. In contrast to other claims which see the 21st century as the ‘era of comparative law’, there are at least four trends which give rise to pessimism: ‘the...
یکی از نمادهای نوین سازی نظام توزیع کالایی، توسعه فروشگاه های بزرگ و زنجیره ای است که بدون صرف هزینه های بالا و برخورداری از دانش تخصصی میسر نخواهد بود. استفاده از ظرفیت سرمایه گذار خارجی یکی از رویکردهایی است که دستیابی به اهداف توسعه ای در این بخش را تسریع می کند. هدف این مقاله نیز بررسی ظرفیت سرمایه گذاری خارجی به ویژه سرمایه گذاری مشترک در گسترش فروشگاه های بزرگ و زنجیره ای در کشور است. نتا...
با نگرش کلی به وضعیت اقتصادی کشور، اقتصاد تک محصولی، وابستگی شدید به درآمدهای نفتی، پایان پذیر بودن منابع نفت و گاز و نیاز به ارز، لزوم صنعتی شدن را روشن ساخته به ویژه بازارهای مناسبی در سطح مناطق خاورمیانه و آسیای میانه جهت جذب فرآورده های گاز سوز ایران وجود دارد. این مقاله به ارزیابی اقتصادی بخاری گازسوز هوشمند پرداخت و نتایج حاصل از ارزیابی های انجام شده در این تحقیق بوسیله نرم افزار کامفار،...
