Labor market regulation

In many countries, the wage floors and working conditions set in collective contracts negotiated by a subset of employers and unions are subsequently extended to all employees in an industry. Those extensions ensure common working conditions within the industry, mitigate wage inequality, and reduce gender wage gaps. However, little is known about the so-called bite of collective contracts and whether they limit wage adjustments for all workers. Evidence suggests that collective contract benefits come at the cost of reduced employment levels, though typically only for workers earning close to the wage floors.

The micro- and macroeconomic effects of the declining power of trade unions have been hotly debated by economists and policymakers, although the empirical evidence does little to suggest that the impact of union decline on economic aggregates and firm performance is an overwhelming cause for concern. That said, the association of declining union power with rising earnings inequality and the loss of an important source of dialogue between workers and their firms have proven more worrisome if no less contentious. Causality issues dog the former association and while the diminution in representative voice seems indisputable any depiction of the non-union workplace as an authoritarian “bleak house” is more caricature than reality.

Before the great recession of 2008–2009, the “flexicurity” model (with flexibility for firms to adjust their labor force along with income security for workers through the social safety net) attracted attention for its ability to deliver low unemployment. But how did it fare during the recession, especially in Denmark, which has been highlighted as having a well-functioning flexicurity model? Flexible hiring and firing rules are expected to lead to large adjustments in employment in a recession. Did the high rate of job turnover continue or did long-term unemployment rise? And did the social safety net become overburdened?

Economists have long recognized that free trade has the potential to raise countries’ living standards. But what applies to a country as a whole need not apply to all its citizens. Workers displaced by trade cannot change jobs costlessly, and by reshaping skill demands, trade integration is likely to be permanently harmful to some workers and permanently beneficial to others. The “China Shock”—denoting China’s rapid market integration in the 1990s and its accession to the World Trade Organization in 2001—has given new, unwelcome empirical relevance to these theoretical insights.

By supporting aggregate demand, including by easing financial constraints that affect businesses and house­holds, accommodative monetary policy increased employment during the 2008 financial crisis and its aftermath. But, monetary policies that ease financial pressures also reduce necessary restructuring that normally contributes to productivity growth. One reason why productivity growth has been weaker in the aftermath of the crisis is that aggressive monetary policy actions have weakened underlying supply-side performance and labor productivity.

Governments regulate employment to protect workers and improve labor market efficiency. But, regulations, such as minimum wages and job security rules, can be controversial. Thus, decisions on setting employment regulations should be based on empirical evidence of their likely impacts. Research suggests that most countries set regulations in the appropriate range. But this is not always the case and it can be costly when countries over- or underregulate their labor markets. In developing countries, effective regulation also depends on enforcement and education policies that will increase compliance.

The share of workers employed part-time increases substantially in economic downturns. How should this phenomenon be interpreted? One hypothesis is that part-time jobs are more prevalent in sectors that are less sensitive to the business cycle, so that recessionary changes in the sectoral composition of employment explain the increase in part-time employment. The evidence shows, however, that this hypothesis only accounts for a small part of the story. Instead, the growth of part-time work operates mainly through reductions in working hours in existing jobs.
