3.3 Hypotheses Testing

Objective of this study is to look at the relationship between profitability and working capital management, the study uses the same hypotheses as used by Raheman & Nasr(2007)

Hypothesis 1

The first hypothesis of this study is as follows:

H01: There does not exist any relationship between efficient working capital management and profitability of firms.

H11: There is a relationship between efficient working capital management and profitability of firms.

Hypothesis 2

The second hypothesis of the study is as follow.

H02: There is no relationship between liquidity and size and profitability of firms.

H12: There may exist a negative relationship between liquidity and size of Pakistani firms and profitability.

3.4 Model Specifications:

The model used in the Study is similar to that used by Raheman & Nasr (2007) which can be specified as;

NOP it = β0 + β1 (ACP it) + β2 (ITID it) + β3 (APP it) + β4 (CCC it) + β5 (CR it) + β6 (DR it) +

Β7 (LOS it) + β8 (FATA it) + ε (Eq. 3.2)

Where:

NOP: Net Operating Profitability

ACP: Average Collection Period

ITID: Inventory Turnover in Days’

APP: Average Payment Period

CCC: Cash Conversion Cycle

CR: Current Ratio

DR: Debt Ratio

LOS: Natural logarithm of Sales

FATA: Financial Assets to Total Assets

E: The error term.

4. Results and Discussion

Two types of analysis are used, descriptive and quantitative. The results of these analysis are discussed in this section

4.1 Descriptive Analysis

Descriptive analysis is the first step in analysis; it will help to describe relevant aspects of occurrence of cash conversion cycle and provide detailed information about every relevant variable. Research has already been conducted in this area of study and a...

...has a negative coefficient – 0.2237.But it is significant at ά. = 5%. It means that if the firm is able to decrease this time period known as cash conversion cycle, it can increase its profitability.

By analyzing the results it is concluded that if the firm is able to reduce these time periods, then the firm is efficient in managing working capital. This efficiency will lead to increasing its profitability.

Current ratio is a traditional measure of checking liquidity of the firm. In this analysis the current ratio has a significant negative relationship with profitability (measured by net operating profitability). The coefficient is – 0.1357. The result is significant at ά. = 1%. It indicates that the two objectives of liquidity and profitability have inverse relationships. So, the Pakistani firms need to maintain a balance or tradeoff between these two measures.
