In this paper we integrate heterogeneous inflation expectations into a simple monetary
model. Guided by empirical evidence we assume that boundedly rational agents, selecting
between extrapolative and regressive forecasting rules to predict the future inflation rate,
prefer rules that have produced low prediction errors in the past. We show that integrating
this behavioral expectation formation process into the monetary model leads to the
possibility of endogenous macroeconomic dynamics. For instance, our model replicates
certain empirical regularities such as irregular growth cycles or inflation persistence.
Moreover, we observe multi-stability via a Chenciner bifurcation.
The paper enlightens popular part of the budget policy – deficit finance. In the
process of securing economic conditions to surpass the current economic crises,
the governments all over the world incline towards debt deficit finance. The
intention is to describe the implications such as multiplier effect, crowding out
effect, correlation between budget and trade deficit. One of them are positive, they
increase the aggregate demand and national income, other negative in term that
they crowd out the private sector from the capital market under increased demand
for loanable funds.
Macedonia's economy was not left behind by the global economic crisis as the
country's macroeconomic policymakers had hoped! Certainly, an economy open at
all and with a high degree of direct dependence on European and global economies
in general should not be saved by the crisis in financial top and then the global
economic. Transmission of negative effects but came a little late economic shocks
in the periphery are often stronger than the epicenter. In these circumstances
macroeconomic policymakers should be more proactive, coherent and dynamic
design of the following measures and economic policies increasingly based on
relevant research and analysis (decision making based on research and analysis).
Therefore, this analysis aims to develop and study in detail the measures in terms of
economy, Science and Technology of Macedonia in order to suggest a more
effective policy in accordance with business cycles, always comparing the
economic measures in other states with which the country has advanced reports on
economic but referring to specific local economic conditions. Accordingly the
specific activities recommended for further action.
Assessing students’ competencies (either implicitly or explicitly) is a routine task for teachers, with many decisions – for example, concerning grading, ability grouping, and difficulty level of questions or materials – being based on these teacher judgments. Given this, judgment accuracy (often referred to as diagnostic competence) is regarded as a central element of teacher professionalism and is thought to affect students’ learning outcomes. So far, however, empirical evidence concerning teachers’ diagnostic competence is incomplete and partly contradictory. As argued throughout this paper, these mixed results can be attributed, to some extent, to the fact that judgment purposes and judgment demands are not adequately taken into account in current research literature.
“Students’ academic self-concept is a good predictor of academic achievement and a desirable educational outcome per se. In this study, we take a closer look at the nature of the academic self-concept in the natural sciences by examining its dimensional structure, its relation to achievement, and gender differences. We analyzed data from self-concept measures, grades and standardized achievement tests of 6036 German 10th graders across three science subjects – biology, chemistry, and physics – using structural equation modeling. Results indicate that (a) a 3-dimensional, subject-specific measurement model of the self-concept in science is preferable to a 1-dimensional model, (b) the relations between the self-concept and achievement are substantial and subject-specific when grades are used as achievement indicators, and ( c) female students possess a lower self-concept in chemistry and physics even after controlling for achievement measures. The refore, we recommend conceptualizing the self-concept in science as a multi-dimensional, subject-specific construct both in educational research and in science classes.”
