This paper investigates the welfare and economic stabilization properties of a fiscal transfers scheme between members of a monetary union subject to sovereign spread shocks. The scheme, which consists of cross-country transfer rules triggered when sovereign spreads widen, is incorporated in a two-country model with financial frictions. In particular, banks hold government bonds in their portfolios, being exposed to sovereign risk. When this increases, a drop bank’s equity value forces them to contract credit and to raise lending rates at the same time as they retain funds to build up their net worth. I show that, when domestic fiscal policy is not distortionary, fiscal transfers improve welfare and macroeconomic stability. This is because fiscal transfers can reduce banks’ exposure to government debt, freeing credit supply to the private sector. On the contrary, when domestic fiscal policy is distortionary, fiscal transfers cause welfare losses, despite stabilizing the economy. This result arises because the distortions caused by funding the scheme outweigh the positive effects of fiscal transfers in smoothing the adjustment of the economy hit by the shock.

Cool paper that shows that such an automatic balancing mechanism across countries may not be a good idea due to the distortionary nature of taxes. That said, I do not understand the European obsession with avoiding sovereign spreads. They reflect risk differentials and sovereign should be sensitive to such price signals. If they are not, they should pay for the consequences of their policies.

Monetary theory reversed: Virtual currency issuance and miners’ remuneration

This study analyzes the macroeconomic implications of virtual currency issuance. It builds on a standard cash-in-advance model extended with (i) ‘virtual’ goods, sold against virtual currency, and (ii) miners, the agents providing payment services. The main finding is that virtual currency growth may have effects opposite to those predicted by monetary theory when miners are rewarded with newly created coins. Declining currency issuance, as in Bitcoin, raises the price of virtual goods, which counteracts the traditional impact of a reduced inflation tax. The paper also shows how fiat money growth affects the welfare effects of virtual currency creation.

What this paper is saying is that there is a sweet spot for virtual currencies where they have been accepted for transactions but are not yet too close to the supply limit. Once supply is too limited to reasonably reward miners, the later start charging higher transaction fees and the cost of the goods bought with virtual currency increases, leading to a net welfare loss. In other words, virtual currencies are cool for a while but are not there to stay.


Are Consumers’ Spending Decisions in Line With an Euler Equation?

Evaluating two new survey datasets of German consumers, we test whether individual consumption spending decisions are formed according to an Euler equation derived from consumption life-cycle models. Measured in qualitative individual changes, our results suggest that current and planned spending are positively correlated, thus supporting the hypothesis of consumption smoothing. Also, current spending is positively correlated with inflation expectations, and negatively with nominal interest rate expectations. Interestingly, the effect of perceived real interest rates is only significant for financial market participants, financially unconstrained households and those with high financial literacy, implying that these are important conditions for the ability to smooth consumption over time. Moreover, these households are better positioned in the wealth and income distributions. In that sense, the ability to smooth consumption may be a channel through which distributional effects of policy shocks may occur. Finally, news on inflation and monetary policy observed by the consumer strengthen the effect of their inflation expectations on current spending, suggesting that imperfect information may also influence the Euler equation relationship.

There are many papers estimating Euler equations, but they usually do it on aggregate data. This paper uses two German surveys and it is with great relief that we learn that the consumption Euler equation is still working well.

Unemployment Insurance Take-up Rates in an Equilibrium Search Model

By Stéphane Auray, David Fuller and Lkhagvasuren Damba

From 1989-2012, on average 23% of those eligible for unemployment insurance (UI) benefits in the US did not collect them. In a search model with matching frictions, asymmetric information associated with the UI non-collectors implies an inefficiency in non-collector outcomes. This inefficiency is characterized along with the key features of collector vs. non-collector allocations. Specifically, the inefficiency implies that noncollectors transition to employment at a faster rate and a lower wage than the efficient levels. Quantitatively, the inefficiency amounts to 1.71% welfare loss in consumption equivalent terms for the average worker, with a 3.85% loss conditional on non-collection. With an endogenous take-up rate, the unemployment rate and average duration of unemployment respond significantly slower to changes in the UI benefit level, relative to the standard model with a 100% take-up rate.

Social Insurance and Occupational Mobility

By German Cubas and Pedro Silos

http://d.repec.org/n?u=RePEc:tem:wpaper:1802&r=dge

This paper studies how insurance from progressive taxation improves the matching of workers to occupations. We propose an equilibrium dynamic assignment model to illustrate how social insurance encourages mobility. Workers experiment to find their best occupational fit in a process filled with uncertainty. Risk aversion and limited earnings insurance induce workers to remain in unfitting occupations. We estimate the model using microdata from the United States and Germany. Higher earnings uncertainty explains the U.S. higher mobility rate. When workers in the United States enjoy Germany’s higher progressivity, mobility rises. Output and welfare gains are large.

By chance, there a two papers with a similar message about unemployment insurance in this week’s issue of NEP-DGE. Both argue that UI is essential in getting good fits on the labor market. This is especially true as the jobs and the labor market become more and more specialized.
