Using the model proposed in Krugman and Taylor’s “Contractionary effects of devaluation” (1978), we examine the macroeconomic effects of shocks to foreign prices. We show that these shocks can be contractionary for two reasons: (i) because they imply a loss of income if an economy has a trade deficit or import prices increase proportionally more than export prices; (ii) because there is a redistribution of income from wages to profits and rent, which leads to a decrease in consumption and output (as the wage earner's propensity to consume is higher than those of profit earners and rentiers). An endogenous reaction of nominal wages to the increase in the price level might lead to even higher increases in prices, but mitigates the negative macroeconomic effects of the foreign price shocks because it reduces their negative distributional effects. If the proportional increase in nominal wages is higher than that of domestic prices, the distributional effect becomes positive. The opposite is the case with markups. If they increase in reaction to higher prices, they contribute to further price increases but they also exacerbate the negative distributional effects. The paper also provides an analytical solution for a general case of the model of Krugman and Taylor.

Since inheriting the Brazilian presidency five months ago, the new Temer administration has successfully ratified a constitutional amendment imposing a radical, two-decades-long public spending freeze, purportedly aimed at sparking an increase in business confidence and investment. In this policy brief, Fernando Cardim de Carvalho explains why this fiscal strategy is based not only on a flawed conception of the drivers of private-sector confidence and investment but also on a mistaken view of the roots of the current Brazilian economic crisis. The hoped-for “expansionary fiscal consolidation” is not likely to be achieved.

A technical analysis shows that the doomsayers who support the euro at all costs and those who naively theorize that a single currency is the root of all evil are both wrong. A euro exit could be a way of getting back to growth, but at the same time it would entail serious risks, especially for wage earners. The most important lesson we can learn from the experience of the past is that the outcome, in terms of growth, distribution, and employment, depends on how a country remains in the euro; or, in the case of a euro exit, on the quality of the economic policies that are put in place once the country regains control of monetary and fiscal matters, rather than on abandoning the old exchange system as such. It all depends on how a country stays in the eurozone, or on how it leaves if need be.
