Testing Static Trade-off Against Pecking Order Models of Capital Structure

Open access
Shyam-Sunder, Lakshmi, Myers, Stewart·1994·National Bureau of Economic Research

Abstract

This paper tests traditional capital structure models against the alternative of a pecking order model of corporate fmancing.The basic pecking order model, which predicts external debt fmancing driven by the internal fmanciai deficit, has much greater explanatory power than a static trade-off model which predicts that each firm adjusts toward an optimal debt ratio.We show that the power of some usual tests of the trade-off model is virtually nil.We question whether the available empirical evidence supports the notion of an optimal debt ratio.

  • The authors state this as an assumption.

    Real investment is exogenous for the sample firms.

    “In this paper, we take real investment as exogenous, because our sample consists of large, public firms, mostly investment grade, most of which should have easy access to the debt market.”
  • The authors state this as an assumption.

    Both the static trade-off and pecking order views assume shareholder wealth maximization as the corporate objective.

    “Note, however, that both views assume shareholder wealth maximization as the corporate objective.”
  • The paper relies on this without support.

    For instrument (1), there is enough serial correlation in individual firms' deficits that the lagged deficit is not too bad a predictor of the deficits forecasted by managers.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Table 7 reports a different sample size

    Minor

    The paper repeatedly describes the sample as 157 firms, but Table 7 says its results cover 175 firms.

  • Table 7 gives conflicting definitions of parenthesized numbers

    Minor

    The Table 7 heading calls the parenthesized numbers t-statistics and also calls them standard errors. Those are different statistics, so both descriptions cannot be correct.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
