We analyse the effect of the anonymisation method multiplicative stochastic noise on the within estimation of a linear panel model. In particular, we concentrate on the panel model with serially correlated regressors. In addition to anonymisation as such, the serial correlation in a data set with only few points in time increases the bias of the within estimator and therefore must be taken into...

Consider a linear model setting in which the explanatory variables are specified by time series. To sequentially test for the stability of the regression parameters in time, we introduce a detector which is based on the first excess time of a CUSUM-type statistic over a suitably defined threshold function. The main aim of this paper is to derive the limit distribution of the detector. By provid...

This paper explores the issue of efficiency in English higher education using data envelopment analysis and stochastic frontier analysis to estimate an output distance function (which incorporates measures of both quantity and quality of teaching and research inputs and outputs) over a thirteen-year period. The study compares the efficiency estimates derived from various estimation methods, and...

Beginning in the mid-1980s, the phenomenon of capital flight from developing countries received considerable attention in the economics literature. Capital flight destroys the domestic macroeconomic environment and decreases transparency and accountability. It restricts financial resources when a country is looking for economic growth and development. The purpose of this article is to measure t...

as a result of higher crude oil prices, in one hand, it is expected that alternative energy resources consumption is increased and consumers change their behavior to decline energy intensity too. on the other hand, more alternative energy consumption can leads to a decline of crude oil aggregate demand. therefore, existence of mutual causality between crude oil price and alternative energy cons...

We construct an endogenous growth model and we employ empirical analysis to investigate the link between foreign aid and production inefficiency in the presence of different political orientations in the recipient country. Using a panel of 124 countries from 1971 to 2007 and the production frontier toolbox, controlling for unobserved heterogeneity, time horizons, the sources of aid, and the tim...

Moody’s databases of corporate issuers of long term bonds and structured products are used to estimate asset correlations across a group of sectors, world regions and products. The estimation of a dynamic factor model for default risk is performed using Bayesian methods. Results indicate that a two factor model rather than the one factor model, as proposed by the Basel II framework, better repr...

Abstract. Since 2021, Russia has maintained a list of unfriendly countries. This and the import ban introduced in 2014 are some main economic sanctions uses to influence trading partners. paper attempts quantify effect putting partner on countries compared Russian ban. The study data trade flows between its partners from UN COMTRADE database for select agri-food products. Employing gravity fram...

Achieving the 2030 sustainable development goals (SDGs) in Nigeria requires and inclusive economic growth. There is no consensus among economists on effect of monetary policy The results previous studies growth are mixed. main objective this paper to evaluate order ascertain if can be used achieve SDGs Nigeria. from 1991 2020 was evaluated using ordinary least squares regression model. findings...

Policy Evaluation and Economic Policy Advice Arguably, one of the most important developments in the field of applied economics during the last decades has been the emergence of systematic policy evaluation, with its distinct focus on the establishment of causality. By contrast to the natural sciences, the objects of our scientific interest typically exert some influence on their treatment stat...
