This paper reviews various approaches to measuring business innovation from the angle of capturing social innovations and offers several methodological and policy conclusions. First, the Innovation Union Scoreboard (IUS) indicators in principle could be useful in settings where the dominant mode...

In the last decade, a number of experiments have stated that spending money on experiences rather than on material goods tends to make people happier. However, the experimental designs used to analyze the relationship between consumption and subjective well-being had several limitations: small...

It was a great surprise to both the Hungarian and the international research community to see how determined and successful were the 2nd and the 3d Orbán-governments in rolling back the results of the post-communist privatizations. In my earlier papers - see Mihályi (2014, 2015a,b) - I showed...

This paper argues that the Phillips curve relationship is not sufficient to trace back the output gap, because the effect of excess demand is not symmetric across tradeable and non-tradeable sectors. In the non-tradeable sector, excess demand creates excess employment and inflation via the...

In Hungary, more than 22% of the FX mortgage portfolio is non-performing and the tendency is worsening. In this paper we propose a solution to effectively reduce the credit and systemic risk inherent to this portfolio, but the proposed model can be applied to other mortgage portfolios in...

We study the adjustment process of a small open economy to a sudden worsening of external conditions. To model the sudden stop, we use a highly non-linear specification that captures credit constraints in a convenient way. The advantage of our approach is that the effects of the shock become...

Optimal power flow (OPF) problems are focussing on the question how a power transmission network can be operated in the most economic way. The general aim in such scenarios is to optimize generator scheduling in order to meet consumption re-quirements, transmission constraints and to minimize...

Let us consider a financially constrained leveraged financial firm having some divisions which have invested into some risky assets. Using coherent measures of risk the sum of the capital requirements of the divisions is larger than the capital requirement of the firm itself, there is some...

To compare the systems of child benefits and of family tax deductions, we create a model with endogenous fertility and a basic income, financed from proportional wage taxes. The deduction's efficiency is presumably lower than the benefit's and may even be lower than that of pure basic income.

We provide a new modus operandi for the computation of the nucleolus in cooperative games with transferable utility. Using the concept of dual game we extend the theory of characterization sets. Dually essential and dually saturated coalitions determine both the core and the nucleolus in...
