In this paper we show the benefits of regional connectivity and specialization to growth. Starting with one region we show how welfare measured by utility per head increases as the number of connected regions increase. We assume a common connectivity infrastructure implemented by satellite, through which the ‘Great Connector’ (GC) is able to add new regions to the pool of connected regions by t...

We analyse how the welfare state, i.e., social insurance that works through redistributive taxation, should respond to increases in risks and to increases in the cost of operating the welfare state. With respect to risks, we distinguish between risks that can be insured and such that cannot (background risks). Insurable risks can be reduced by costly individual selfinsurance and by costly socia...

Using a two-good, two-country model, we examine macroeconomic adjustment by allowing for decreasing and increasing marginal impatience (DMI and IMI). In the reference case where both countries have IMI, a negative output shock in one country lowers the interest rate and both countries’ welfare levels in steady state, whereas, when either one country has DMI, the negative income shock raises the...

I develop a tractable growth model that allows me to study analytically transition dynamics and welfare in response to a deficit-financed cut of the tax rate on distributed dividends. I then carry out a quantitative assessment of the Job Growth and Taxpayer Relief Reconciliation Act (JGTRRA) of 2003. I find that the Act produces lower steady-state growth despite the fact that the economy’s savi...

in 1930s, the idea of providing general welfare and welfare state appeared in industrial countries due to the belief in the ability of left forces in solving misfortunes that people entangled in; because of financial crisis in industrialized societies, expanded poverty, starvation and epidemic diseases which led millions of people to the hopelessness. welfare states achieved outstanding success...

Empirical evidence suggests that parents with higher levels of education generally attach a higher importance to the education of their children. This implies an intergenerational chain transmitting the attitude towards the formation of human capital from one generation to the next. We incorporate this intergenerational chain into an OLGmodel with endogenous human capital formation. In absence ...

Due to the importance of longest path analysis in networks of queues, we develop an analytical method for computing the steady-state distribution function of longest path in acyclic networks of queues. We assume the network consists of a number of queuing systems and each one has either one or infinite servers. The distribution function of service time is assumed to be exponential or Erlang. Fu...

In this paper, we introduce non-interest profit/loss sharing (PLS) banks into a three-period overlapping generations model. Two types, (low- and high quality) investments are assumed and capital accumulation and level of output in the steady state is considered. Then, administrative rationing is introduced to the model. It is shown that the level of capital accumulation and output in equilibriu...
