Determinants and Consequences of Budget Reallocations*

Abstract

We investigate the determinants and consequences of budget reallocations—that is, corrective changes to the budget made during the year. Using proprietary data from a large consumer goods manufacturer, we analyze the extent to which initial budgeting decisions drive reallocations. Examining this relationship is important because initial budget negotiations are often troubled by power struggles and politicking, which may give rise to the need for reallocations. We hypothesize that one important driver of reallocation decisions is the firm's aim to correct systematic deviations from the optimal initial budget that were driven by lobbying during the initial budgeting process. We find evidence that is consistent with this prediction. In a more exploratory analysis, we show that reallocations do not have the desired effects on market performance. In particular, budget cuts are negatively associated with a product's change in market share. More surprisingly, while budget increases do help product lines achieve their sales targets in the last quarter, they do not boost market share. Our results demonstrate that efficient investment planning is essential to achieve an improvement in market performance.
