The Economy of Expectations

Policymakers must go beyond data to understand how households and businesses shape their future decisions.

The RBI’s recent 0.25 percent repo rate hike reflects concerns over persistent inflation. While higher rates are expected to moderate borrowing and discretionary spending, their effect is typically gradual. With the festive season underway, consumer demand is likely to remain resilient, as purchase decisions are often driven by planning, sentiment, and tradition rather than short-term changes in interest rates. Rather than attempting to suppress demand, the RBI appears to be signalling caution on the inflation outlook.

The impact of a repo rate hike varies across households, influenced by financial circumstances, debt obligations, income stability, and spending priorities. For affluent consumers with strong cash flows and limited borrowings, a modest increase in interest rates is unlikely to materially affect consumption in contrast to salaried borrowers with housing loans. However, consumer behaviour rarely follows a uniform pattern. Families planning major festive purchases may choose to absorb the additional borrowing cost, utilize savings, or adjust repayment strategies rather than defer spending. Ultimately, purchasing decisions are also driven by aspirations, confidence, and financial resilience, making the overall economic response to monetary policy often difficult to predict.

Fundamental Challenge

Governments and central banks face a fundamental challenge that the data they rely on reflects the past, while their policies seek to influence future behaviour. Indicators such as GDP growth, inflation, and industrial output explain what has already happened but do not always predict how people will respond tomorrow. This creates three key challenges. First, spending patterns can shift as individuals anticipate the future impact of current policies. Second, policy actions often shape public perception, sometimes producing outcomes different from those intended. Third, while statistics explain past trends, future economic activity is driven largely by expectations around inflation, taxes, employment, and income.

Managing an economy involves far more than analysing data. Policymakers must also understand how households and businesses interpret policy signals and shape their future decisions.

This challenge lies at the heart of the work of this year’s Economics Nobel laureates, Robert Hall of Stanford University and Michael Woodford of Columbia University, who dedicated much of their research to understanding how expectations influence economic behaviour and policy effectiveness.

To appreciate their contribution, it is important to look back at the evolution of modern macroeconomic thought. In the decades following the Great Depression, Keynesian economics dominated policy, arguing that governments could reduce unemployment through higher public spending and lower interest rates, even at the cost of moderate inflation. This framework was challenged in the 1970s when oil price shocks led to stagflation, an unusual combination of high inflation and rising unemployment. Traditional stimulus measures failed to deliver the expected results, exposing a key weakness in prevailing economic models. They largely overlooked how individuals and businesses adjust their behaviour based on expectations about the future. Recognizing this gap, Robert Hall and Michael Woodford helped transform macroeconomic thinking by placing forward-looking expectations and human behaviour at the center of economic analysis and policymaking.

Before Robert Hall’s landmark 1978 work, economists generally assumed household spending closely tracked current income. Hall challenged this view, arguing that families prefer a stable standard of living and base spending on expected lifetime income rather than current earnings alone. This concept, known as consumption smoothing, suggests people often adjust spending in anticipation of future income. For instance, someone expecting a year-end bonus may gradually increase spending before receiving it. Consequently, consumption tends to change significantly only when households encounter unexpected events such as promotions, job losses, or financial shocks. Hall and Frederic Mishkin later showed that this behaviour varies across households: families with savings and credit access can smooth consumption, while cash-constrained households are more likely to spend additional income immediately.

Reshaping Thought

While Robert Hall transformed our understanding of consumer spending, Michael Woodford reshaped modern thinking on inflation, business behaviour, and central banking. In his influential 2003 framework, Woodford argued that in modern economies driven by credit and digital payments, central banks affect economic activity primarily through interest rates rather than the money supply.

He also emphasized that prices are often “sticky,” as frequent price changes involve costs and operational challenges. Consequently, businesses set prices based on expectations of future costs, demand, and inflation, making economic outcomes inherently forward-looking.

Woodford further highlighted the need to distinguish between demand and supply shocks.

A key insight from their work is that a central bank’s most powerful tool is not money creation but its ability to shape expectations. Economic decisions are influenced as much by what households and businesses anticipate about the future as by current policies. This helps explain why temporary policy measures often have only short-term effects.

Equally important is policy credibility. When institutions consistently follow through on their commitments, their guidance can influence behaviour even before formal action is taken. Conversely, repeated departures from stated objectives can weaken public trust and lead consumers and businesses to act more cautiously. In modern economies, credibility is therefore a critical asset.

The insights of Hall and Woodford continue to influence the decisions of India’s key economic institutions. For the RBI, the priority is maintaining stable inflation expectations through a clear inflation target and consistent communication. The government, meanwhile, can deliver stronger long-term outcomes by focusing on infrastructure investment.

For businesses, strategic decisions should be guided by long-term trends in interest rates and inflation rather than short-term policy shifts.

India’s Viksit Bharat 2047 vision reflects three key principles aligned with Hall and Woodford’s insights. First, long-term prosperity depends on investing in human capital through education, healthcare, and skill development. Second, sustainable growth requires expanding productive capacity through stronger infrastructure, energy security, and efficient logistics. Third, institutional credibility, supported by transparent policies, predictable regulations, and monetary stability, encourages long-term investment and confidence. The challenge of policymaking, after all, lies in understanding the people behind the numbers.
