could confound my findings. Specifically, I control for a variety of innate firm
characteristics that prior research has shown to be related to firms’ investment behavior.
These controls include firm size (
SIZE
), tangible fixed assets (
TANGIBILITY
), cash flow
to sales (
CFO_SALE
), length of the operating cycle (
OPERATING_CYCLE
), dividend
payouts (
DIV
), market-to-book ratio (
MTB
), frequency of losses (
LOSS
), capital structure
(
CAP_STRUCTURE
), and bankruptcy risk (
Z_SCORE
). I measure
SIZE
as the
natural
logarithm of end of year market value of equity and
TANGIBILITY
as the ratio of gross
value of
PPE
to total assets.
CFO_SALE
is the ratio of cash flow from operating activities
to net sales.
OPERATING_CYCLE
is the natural logarithm of the sum of receivables to
net sales and inventory to cost of goods sold multiplied by 360.
DIV
is
an indicator
variable that takes the value of one if the firm paid a dividend, and zero otherwise.
MTB
is the ratio of market value of total assets to book value of total assets.
LOSS
is an
indicator variable that takes the value of one if the firm’s net income before extraordinary
items is negative, and zero otherwise.
CAP_STRUCTURE
is the ratio of long-term debt to
the sum of long-term debt and market value of equity.
Z_SCORE
is
a measure of
bankruptcy risk (distress) computed following the methodology in Altman (1968).

Consistent with prior literature (e.g., Biddle and Hilary 2006), I predict that firms that are
larger, more profitable, and have more tangible fixed assets, higher
MTB
ratio, and lower
bankruptcy risk, will have higher
investment in
PPE
(capital expenditures).
Further, I include closely-held shares (
CLOSELY_HELD
) in equation (4). Prior
research (e.g., Berle and Means 1932; Jensen and Meckling 1976; Ang et al. 2000)
suggests that the separation of ownership and control increases the level of agency
conflict between insiders and outside shareholders and, hence, could affect managerial
investment decisions.
CLOSELY_HELD
is measured as percentage of closely-held shares

as reported by WorldScope.

I also include
BIG4_5
,
an indicator variable
equaling one when the firm’s auditor is either one of the big four or five auditors and zero
otherwise, to control for any potential effect this governance variable has on over-
investment (i.e., the interaction between
BIG4_5
and
OVER_INV
in equation (4)).
21
Finally, I include country and industry fixed effects in equation (4) to control for cross-
country differences (e.g., rule of law) and for industry-specific
shocks that could affect
firm’s investment behavior.
In the context of equation (4),
OVER_INV
is increasing in the likelihood of over-
investment. The estimated
β
3
coefficient measures the incremental effect that
OVER_INV
has on investment in
PPE
(
CAPEX
) after
IFRS
mandatory adoption. Therefore, if over-
investment in
PPE
is
lower in the post-
IFRS
period relative to the pre-
IFRS
period as
predicted by hypothesis 1 (H1), I expect a significantly negative
β
3
coefficient.
