In Blanchard's WS PS Model: An Increase In Labor Militancy

In Blanchards Ws Ps Model An Increase In Labor Militancy Or The M

In Blanchard’s WS-PS model, an increase in labor militancy or the mark-up must result in either a wage-price spiral or a higher rate of unemployment. The WS-PS diagram illustrates this relationship by representing the wage-setting (WS) curve and the price-setting (PS) curve within the context of the labor market and inflation dynamics. The WS curve depicts the relationship between real wages and employment, influenced by workers’ negotiations and militancy levels, whereas the PS curve reflects firms’ pricing strategies based on costs and mark-ups. When labor militancy increases, workers demand higher wages, shifting the WS curve upwards or to the left, signifying higher wage demands at each employment level. Alternatively, an increase in mark-up—reflecting greater market power of firms—raises costs for firms, shifting the PS curve upward or to the left. Both shifts reduce real wages and increase inflation pressure. These shifts can lead to a wage-price spiral, where higher wages fuel inflation, prompting further wage demands, or alternatively, they can cause unemployment to rise if firms cannot sustain higher costs without reducing employment. This framework captures the dilemma faced by policymakers during the 1970s when inflation soared alongside stagnating or rising unemployment—a phenomenon known as stagflation. During this period, the simultaneous occurrence of supply shocks, increased union militancy, and oil crises exemplified the dynamics described by the WS-PS model, where attempts to curb inflation often exacerbated unemployment, illustrating the trade-offs inherent within the model’s predictions.

David Purdy’s essay, “The Wages of Militancy,” proposes a way out of this dilemma by emphasizing the importance of institutional and structural reforms that mitigate the adverse effects of increased militancy. Specifically, Purdy suggests that stronger social safety nets, collective bargaining reforms, and policies aimed at productivity enhancement can break the cycle of wage-price spirals. The logic, grounded in the WS-PS framework, posits that if workers’ demands are anchored by real productivity growth rather than market power alone, then wage increases can be more sustainable without triggering inflation or unemployment cycles. By shifting the WS curve in a manner that reflects genuine productivity gains and institutional protections, the model indicates a more stable equilibrium where real wages and employment can grow concurrently. This approach seeks to reduce the volatility inherent in the traditional WS-PS relationship by fostering a middle ground between workers’ demands and firms’ pricing power, thus providing a pragmatic pathway out of the wage-price inflation trap during tumultuous economic periods.

The Blanchard WS-PS model serves as a vital analytical framework to understand the interplay between wages, prices, and unemployment in the context of labor market dynamics. Central to this model is the notion that shifts in labor militancy or market mark-ups influence the equilibrium within the economy, often leading to either inflationary spirals or increased unemployment. The WS curve, representing wage-setting behavior, reflects workers’ wage demands, which are influenced by their bargaining power and militancy levels. The PS curve, on the other hand, embodies firms’ price-setting behavior, which is affected by factors such as market competition, productivity, and market power or mark-ups.

When workers become more militant, demanding higher wages, or when firms increase their mark-ups, the WS or PS curves shift, respectively. An upward shift in the WS curve manifests as higher wage demands at each level of employment, which, if unaccompanied by increases in productivity, can ignite inflationary pressures—leading to a wage-price spiral. Conversely, a rise in mark-up firms charge or cost structures can cause the PS curve to shift upward, compounding inflationary pressures. These movements can destabilize the economy’s delicate balance, precipitating a scenario where inflation accelerates without a corresponding increase in employment—what was observed notably during the 1970s stagflation. The combined effects of oil shocks, union militancy, and inflation expectations aligned with the WS-PS framework’s predictions, illustrating the complex trade-offs faced by policymakers during that era.

In examining the “way out,” Purdy’s proposal hinges on structural reforms designed to stabilize the relationship between wages and productivity while insulating the economy from inflationary spirals. By promoting policies that enhance productivity growth and strengthen institutional safeguards—such as collective bargaining agreements rooted in productivity rather than sole market power—Purdy suggests that it is possible to shift the WS curve towards a more sustainable path. The aim is to negotiate wage increases that reflect genuine productivity gains, thereby reducing the tendency toward inflation triggered by unrestrained wage demands. This approach leverages the WS-PS model’s logic to illustrate that reforms fostering stable, mutually beneficial wage-setting and price-setting relations can alleviate the long-standing trade-off between inflation and unemployment, especially in turbulent economic environments like the 1970s.

The WS-PS model thus encapsulates a core insight of macroeconomic policy: balancing the demands of labor and the realities of market power is essential to maintaining economic stability. The 1970s exemplified the consequences of neglecting this balance—marked by stagflation and economic uncertainty. Purdy’s recommendation advocates for a paradigm shift—from confrontational, inflationary wage bargains to a cooperative, productivity-based approach—aiming for sustainable growth and stable inflation rates. Such a shift would modify the position and shape of the WS and PS curves, fostering an equilibrium that minimizes the destructive oscillations of the wage-price spiral while promoting full employment and price stability.
